Wearable, Feminine, Organic, & Ethical Jewelry

I received my formal training at the University of Vermont, where I studied metalsmithing, drawing, and painting. I always loved the arts, but figured it wouldn’t become a career beyond college. I began creating a line of jewelry as a side business while working as a bench jeweler for other renowned jewelry artists in Vermont and later in California. Since selling my first designs in 2007, Kristin Coffin Jewelry has evolved from a one-woman show in a tiny apartment studio, to a team of talented artisans. It’s now a family affair – including even my husband, Drew, and brother, Nick, and my adorable rescue pup, Pica. We’re based in sunny Denver, Colorado, which provides never-ending inspiration and adventures. 

Natural forms in the local landscape inspire the balance between structured and organic elements found in our jewelry. Each piece is individually crafted in the US by our team of metalsmiths, using traditional metalsmithing techniques complemented by the hippest technology in the industry. I still spends days at the bench each week and has a large hand in the production of every single piece. Using only recycled metals and conflict-free gemstones, our jewelry forms a unique relationship between the earth’s designs, its resources, and its inhabitants. I prefer not to follow trends, but rather to design pieces that are sustainable and versatile, rooted in originality and a connection to the environment and community.

I'm the luckiest lady on earth: translating my passion in a way that resonates with others. I'm so thankful for my clients for their support and inspiration.

▶ RUSH ORDERS: Thanks for your patience; handcrafted jewelry takes time to fabricate but is well-worth the wait! If you need a piece rush-ordered, please contact me with your specific request BEFORE placing your order. I can sometimes accommodate a rush request but not always, and not with all pieces. If it is possible to accommodate, rush fees may be applied to cover shipping fees from vendors, overtime labor, etc. Fees depend on the piece and turnaround time requested, so please be specific with your item request and exact deadline when inquiring. (Link to the item, and also provide the finger size, metal color, and deadline needed.)

▶ Please take a moment to read through all of the following Policies and FAQ's before ordering. If you don't see an answer to your question, please contact me directly and I'll respond to your message as soon as possible.

Returns and exchanges
Everything I craft is made with the utmost care, using the finest materials. If you are somehow dissatisfied with your order, please contact me as soon as possible. Items may be returned/exchanged with a postmark date within 7 days of receipt of item. Pieces must be in the same condition as when they were received, and must be in original packaging with all cards, boxes, ribbon, packing, etc. included. Item must be sent via FedEx or UPS overnight or 2-day, or via USPS Express. It must be fully insured and with a Delivery Confirmation (tracking and proof of shipping). Customer pays return shipping costs. Customer will be refunded the full amount, less shipping and a small 8% restocking fee to cover labor for refurbishing/resizing/processing. If a ring was made-to-order, or is a sale or one-of-a-kind ring, it will incur a greater 10% restocking fee. Any rush fees paid when placing the order are non-refundable. Any cancelled orders will result in a 10% restocking fee. Custom orders are final sale; they are non-returnable and non-exchangeable.

Happiness with your jewelry is my top priority. I pride myself not only on exceptional jewelry, but the best customer service as well. Please contact me with any questions or concerns as soon as possible after receiving your order.

It's very important to find out the correct finger size before ordering, since sizing is the first step in making a ring. Many pieces cannot be resized, and would require a complete remaking of the piece. It is the buyer's responsibility to indicate the correct size upon purchasing. If a ring is able to be sized after checking with me, I would be happy to size it for $75 (plus any cost of additional gold needed), and shipping both ways. Due to the high volume of orders I have each week, I ask for 4 weeks to complete a resizing after I receive the ring.

Thanks for understanding!

Buyers can pay by using any major credit or debit card, or through PayPal's safe payment platform. Just follow the simple steps at Etsy's checkout to complete your payment. Made-to-order items will not be started until full payment is made. *For orders shipping within Colorado, 7.62% sales tax will automatically be added at checkout.
Shipping rates and carrier are determined by the final price of your order:

• $0 to $200 – USPS Priority Mail; includes tracking, but does not include insurance
• $201 to $499 – USPS Priority Mail; includes insurance, tracking, signature required at delivery
• $500 to $3,499 – UPS Two Day Service; includes insurance, tracking, signature required at delivery
• $3,500+ – UPS Standard Overnight Service; includes insurance, tracking, signature required at delivery

If you would like to add insurance to a shipment valued under $200, please let me know ahead of time and I can update the listing prior to checkout. Similarly, please contact me if you wish to upgrade to UPS Two Day or Overnight shipping. If shipping via UPS, a small additional amount will be invoiced for items sent to Alaska and Hawaii.

It is your responsibility to make arrangements to sign for and receive your package. If you're at work all day and have a package shipped to your home, that means you'll have to make arrangements to be home to receive it that day. All insured items will require a signature, and cannot be left at the door. If you're at work, perhaps shipping to your work address is better so you can be there to sign for it. Or a friend or family member who is around during the day to sign. Feel free to send me a message with the shipping address that works best for you.

*UPS will only attempt delivery 3 times before the package is sent back to me. If it's sent back to me, re-shipping will be at the cost of the customer. If you know you'll be out-of-town at any point, please send me a message with the dates you'll be traveling. I'll make sure not to ship during those dates. Keep in mind packages sometimes ship early, so notify me of any dates you are traveling, even early ones.

All orders ship via FedEx Priority International service. Prices vary by country. Please contact me with your postal code for a shipping quote before placing your order.

The buyer is responsible for any additional taxes, duties, or brokerage fees. You can check with your country's local Customs office or on your postal website to estimate what you can expect to pay in fees. It is the customer's responsibility to know the customs laws in their country and to alert me if there are restrictions or other issues that I need to be aware of.

Every so often a package can get held up in Customs. I cannot be responsible for any delays in delivery due to Customs. Buyer agrees to take FULL responsibility for the risks involved in international shipping (delayed delivery, payment of duties, etc.). That being said, I ship internationally a few times each week, and have yet to encounter a lost package in all my years. I use only the safest, insured, trackable method with FedEx.
Additional policies and FAQs
A: Unfortunately, I'm unable to take on custom work. If you like an item, but would prefer a different stone or metal, please contact me, since a slight variation might be possible. Link to the specific listing(s) to let me know which item you have in mind. I do not make any custom orders/variations in silver. Customizations can only be in gold (or sometimes platinum or palladium).

A: Unfortunately, I'm just so busy with orders from my collection that I'm unable to set client-supplied stones, or sell empty mountings. I'm only able to keep my business small and personal by narrowing the scope of what I take on, which means only selling completed rings from my collection.

A: Unfortunately, no. Although I use recycled metals, that means that I purchase them from refineries who supply only refined metals that come from previously-mined sources. The metals may have come from old jewelry at one point in their life, but then they went through a very long and expensive process to reconstitute the molecular structure of the metal to make it usable as if it were new again. I cannot melt down or re-work your old jewelry. If the piece isn't sentimental, I recommend sending it to a trusted refinery to get the trade-in value for your old jewelry. You can then use that money toward buying your new Twig ring. (A great way to keep the recycling process going!)

A: No, the jewelry is all solid metal with no twig inside. Real twigs are used to create a mold that contains all of the original details of the twig's surface. Molten metal fills that mold, creating a solid casting with the exact surface texture of the real twig used. The ancient process is called "lost-wax casting," and dates back nearly 5,000 years.

A: Unfortunately, I cannot make my gold designs in sterling silver because its not economical. The labor involved in some pieces would drive the cost of a silver piece up too high to be reasonable. I strongly recommend considering white or yellow gold. Although sterling can last with extra care, it is not as well-suited for years of everyday wear or for people who work with their hands. Golds will hold up better to everyday wear, and will require less maintenance over time.

A: I do not keep all finger sizes and colors of each piece in stock. Instead, I'll begin making your jewelry especially for you after an order is placed. This is referred to as "made-to-order" since pieces are made to specifications after ordered. Handcrafted jewelry takes time to make, so your piece may take from 4-9 weeks to craft before it ships. (*The current turnaround time on all pieces can be found at the top of this Policies page.)

A: The Rose Cut is a historic cut first used on diamonds in the early 1500's. It was meant to resemble an opening rose-bud when used on a transparent diamond. The actual characteristics of the Rose is that the bottom of the diamond is flat, and forms a hemisphere or low pyramid above, covered with small facets. This is unlike the contemporary Round Brilliant Cut used commonly used today, which has a pointy cone bottom, and flat top. Rose cuts can be any shape, like oval, marquise, pear, oblong, or freeform--as long as they're flat on the bottom, and gently faceted all along the top. The Rose has a subtle, earthy, romantic feel.

A: Until fairly recently, diamonds that weren't clear, or some other fancy color like blue, canary yellow, or pink, were thought inferior by society's standards. Recent artists (only since the late 70's/early 80's) questioned the notion of "value" and the social norms associated with the white diamond. The once thrown away diamonds with inclusions, color variations, opacity, and ranging colors are now celebrated as unique, rare, and bold and daring in the art jewelry world. Now these diamonds are called "rustic," "raw," or "natural" diamonds. They're gaining a bit more popularity with independent artists, but are still slow to catch on in the commercial world of mass-produced jewelry. These diamonds are graded differently than traditional white diamonds. The Four C's don't apply in the traditional sense. Rustic Cuts have their own standards, and different levels of value based on their rarity. Size/carat weight still matter, as does the quality of the cut and polish on the stone. Some colors are also rarer than others, and so will be more costly. What I love most about them is that each is entirely unique. You can always find two VS1/H diamonds, but finding two of the exact same rustic Rose Cuts can be almost impossible. This makes each and every diamond one-of-a-kind, and entirely unique. I love pairing the Roses with my Twig bands, because the facets play nicely with the branch's soft texture.

A: Go into a trusted local jewelry store that's known for having capable sales staff. They'll size your finger free of charge--I swear, this isn't strange to do at all! All jewelry stores across the country will help you for free, without you even needing to pretend to want to buy anything there. Try to go in on a day when you feel most "normal" in size. Our fingers fluctuate a lot from hour to hour, day to day, and season to season. Some people's fingers will change an entire size from winter to summer, while other people's may not even differ noticeably. Try to avoid going to get sized right after a workout, or on a sweltering hot day, or right after waking up (all of which will cause swollen fingers). Alternately, if it's snowing and freezing outside, you'll want to try to warm up your body enough that your fingers aren't unusually small when being sized. Our bodies are moving, changing things, while a metal ring is static. The goal is to find a size that fits the best *most* of the time. Try to figure out your average size by going on an average day. Also, be sure that the sizers the jewelry store uses are similar in width and feel as the ring you plan on purchasing. For example, a thin little 1.5mm sizing ring will feel much looser than a 5mm wide band of the same finger size will fit. The wider the ring, the more skin it must displace, and therefore the tighter it will feel. This is also true if you plan on wearing multiple stackable rings on a finger, or a wedding and engagement ring next to each other. They'll act and feel like one wider ring, so you may need to order a slightly larger size for each. Make sure the sales staff knows how wide the actual ring(s) is that you plan on ordering. They can compensate for the width by using a sizing band of the appropriate size, or stacking multiple thin bands to simulate stackables.

It's absolutely crucial that you find out your correct size before ordering. Many styles cannot be resized, or will cost extra to be sized again. It is your responsibility to determine your correct size. If you're concerned about which size to order for a particular style, I am happy to advise you as best I can. Just write me with your inquiry.

A: I completely understand wanting to see pieces in person. Unfortunately, I don't have a public showroom, just a private studio. I do get many, many requests to meet in person, but at this time I'm not able to do so. I love how my business is small and personal, but I'm only able to keep it that way by being strict about spending lots of time in the studio. Unfortunately, meeting in person means an afternoon spent away from it. With all the requests I receive each week, I wouldn't be able to complete all orders or keep this business running smoothly.

Additionally, my rings are made-to-order with the lead time posted on my shop's home page, or at the top of these Policies. That means that I don't keep a large inventory of pieces since items are made as they're purchased according to a client's color preferences, finger size, etc. Of course, I'm more than happy to answer any questions via Etsy's messaging system or through email.

A: Polished means a high-shine, mirror-like finish. (Think shiny gold!) It's the finish most often seen on commercially-made jewelry. A matte finish is not as shiny, with a duller overall look. A matte finish is often referred to as "brushed" or "satin." These finishes are used more frequently by artisans with handmade jewelry. I use the matte satin finish on nearly all of my bezel settings in rings. The matte satin is a nice contrast to a sparkling diamond or gemstone, and gives the jewelry a contemporary feel.

A: I use the words "emerald" and "radiant" for the same radiant faceting style in many of my ring descriptions and titles on Etsy. I use both words since I have to anticipate the search terms clients type in to Google, Etsy, etc. If I only used "radiant," and a shopper searches for "emerald," they'd never find my website, Etsy shop, or rings. The purpose of using both words is for SEO (search engine optimization). That's why you'll often see "emerald" rings, as well as "radiant" rings in my shop, even though both stone cuts are the same. Each title you create is another chance to be found online. By varying the titles, there are more chances floating around out there online, and a better chance of being seen by shoppers who may not be typing in the exact same language while searching.

As for what they are technically, radiant is a type of faceting style, but is also an emerald/octagon shape. "Emerald" is the more commonly-used term, encompassing both the stepped-cut and radiant cut faceting styles. Step cuts are just as they sound: more linear, stepped facets, as opposed to the triangular facets seen in radiant cuts. Typically the type of gemstone dictates whether it will be cut in a radiant or stepped style. For example, actual green emerald gemstones are usually in the more traditional step cut style, since their ocular properties don't really reflect much light back up to the eye anyhow. For minerals with superior refractive properties, such as Moissanite or diamond, optimizing the facets will create much better sparkle. Step cut emerald-shaped diamonds are not nearly as sparkly as radiant-cut emerald-shaped diamonds. The triangular facets and particular angles of radiant cutting are optimal for fire and brilliance.

In summary, radiant cuts and emerald cuts are both an overall emerald/octagon/rectangular shape. Because the shapes are the same, they're often interchanged frequently in jewelry stores and in common conversation (even though they're technically different faceting styles). Using both words in titles/descriptions on my Etsy page likely further confuses the issue. But the varying titles help me to be found by clients who have never even heard the term "radiant" before, and wouldn't know to search for it.

The term of "emerald" is so much more popular in our society, and is the search term used much more often by shoppers. It makes sense to use that word in titles and descriptions, even though the faceting style is radiant. I'm even able to look at the search stats for my shop, and see exactly how shoppers find me. For example, the search term "emerald cut engagement ring" is the #2 most searched term on Etsy by my clients. The term "radiant cut engagement ring" ranks at around #30. In summary, shoppers search everything else imaginable before they type in "radiant" when shopping for their ring. Although they may be searching "emerald," they come upon my radiant cut rings and find what they're looking for. If all of my rings were titled, "radiant," shoppers would never find the rings they're truly looking for.
