We use the finest diamond simulant available on the market, especially made for our products. Our diamond simulants are not natural diamonds, but are made specifically to replicate the beauty and sparkle of a perfect D color flawless natural diamond and are cut exactly the same way. They are not synthetic lab diamonds and will not test as real with any diamond tester, but will last a lifetime when properly cared for.

The materials and formula used to create our simulants are a trade secret. We searched far and wide all around the globe to find the perfect stones for our customers and we stand behind them with our 100% Happiness Guarantee.

We use the same sizing scale as the fine jewelry stores in a local mall and they will size you for free. Please do not use online sizers or purchase a mandrel from a online retailer. We have frequently seen them give inaccurate results.

It is important to properly care for Sterling Silver jewelry to keep it looking brilliant for years to come.

Remove your jewelry when doing housework, working out, or any activity that may damage your ring.

Remove your jewelry when showering or bathing.

Remove your jewelry when applying lotions, using hairspray, makeup or chemicals.

As a rule of thumb, it’s always best to put on your jewelry last when getting dressed.

Clean your sterling silver jewelry with a silver polish, a baking soda paste, or a silver dip/foam, such as Goddard's silver polishing foam.
