Hello! I'm Tatiana & welcome to my Etsy store!

SIEFF is my new venture & full time job. On this website, you'll be able to shop all sorts of handcrafted jewellery & loose gemstones using top quality precious metals and gemstones. It is absolutely imperative to me that all my materials are sourced as ethically as possible.

After finishing my undergraduate degree in Geography, I immediately threw myself into diamonds. I studied at the Gemological Institute of America (GIA), completing the Graduate Gemology, Pearl Graduate & Accredited Jewellery Professional diplomas. I spent two years working at a well-known high end Bond Street jeweller and then moved into a small firm in Hatton Garden where I was given a great position in diamond buying. I have accomplished a lot, and for that I am very grateful & proud of myself.

Aside from jewellery and gemology, I am also a lover of books, yoga, language learning, Japanese culture, horror films & ghosty things, travelling, comedy & cacti.
