Untreated Gemstone Jewelry For Sale on 1stDibs
On 1stDibs, you can find the most appropriate piece of untreated gemstone jewelry for your needs in our varied inventory. Every item for sale was constructed with extraordinary care, often using Platinum, 18k Gold and Gold. You can easily find a 1 antique edition and 13 modern creations to choose from as well. Making the right choice when shopping for an item from our selection of untreated gemstone jewelry may mean carefully reviewing examples of this item dating from different eras — you can find an early iteration of this piece from the 20th Century and a newer version made as recently as the 21st Century, both of which have proven very popular over the years. A choice in our collection of untreated gemstone jewelry from Merkaba, Fine Jewels UK and AB Jewelry NYC — each of whom created a beautiful version of this treasured accessory — is worth considering. While most can agree that any object in our assortment of untreated gemstone jewelry from our collection can easily elevate most outfits, but the choice of a Beryl version from the 8 available is guaranteed to add a special touch to your ensemble. An emerald cut version of this piece has appeal, but there are also heart cut and cushion cut versions for sale. When shopping for an option in this array of untreated gemstone jewelry, you’ll find that there are less available pieces for unisex or men today than there are for women.
How Much is a Untreated Gemstone Jewelry?
Prices for a piece of untreated gemstone jewelry can differ depending upon size, time period and other attributes — at 1stDibs, these accessories begin at $390 and can go as high as $260,000, while this accessory, on average, fetches $12,500.
