We do not work with semi-things of any kind, synthetics, fusion, imitations, baths, veneers, , zirconia, moissanite, plastics, resins, glass, paraguayite, etc... Synthetic here is a dirty word. The internet is full of this. All the stones are ours, legitimate, often purchased rough and cut according to our criteria. We only work with 925 silver and 18K gold, white or yellow, often by order & this is the reason of our sucees & growth. We have a stock of jewelry with natural stones, mounted in sterling silver. Gold jewels only by order All of our jewelry comes with a Gemological Certificate of Authenticity, numbered for future reference.
