Untreated Gems For Sale on 1stDibs

There is a broad range of untreated gems for sale on 1stDibs. These distinct designs — crafted with great care and often made from gold, silver and 18k gold — can elevate any look. Find a collection of 76 vintage versions or 658 modern creations for a more contemporary example of these cherished accessories. Our collection is diverse and broad-ranging, and pieces in stock date back to the 18th Century while others were produced as recently as the 21st Century. Pieces in our collection of untreated gems made by Art Deco jewelers — as well as those associated with contemporary — are very popular. Versions of these items have been a part of the life’s work for many jewelers, but those produced by Gems and Jewels UK, Polya Medvedeva Jewellery and Merkaba are consistently popular. Lovers of these pieces agree that it’s a versatile accessory, but a selection from our variety of 290 sapphire versions can add an especially stylish touch. A selection of oval cut, round cut and cushion cut can be found today on these pages. When shopping our range of untreated gems, you’ll find that there are less available pieces for men today than there are for women.
