Opal 18ct For Sale on 1stDibs
On 1stDibs, you can find the most appropriate opal 18ct for your needs in our varied inventory. Every item for sale was constructed with extraordinary care, often using gold, 18k gold and yellow gold. You can easily find a 93 antique edition and 405 modern creations to choose from as well. Making the right choice when shopping for an opal 18ct may mean carefully reviewing examples of this item dating from different eras — you can find an early iteration of this piece from the 19th Century and a newer version made as recently as the 21st Century, both of which have proven very popular over the years. Finding an appealing opal 18ct — no matter the origin — is easy, but Renata Bernard, Giulians and Fei Liu each produced a popular version that is worth a look. A cabochon version of this piece has appeal, but there are also oval cut and round cut versions for sale. When shopping for an opal 18ct, you’ll find that there are less available pieces for unisex or men today than there are for women.
How Much is a Opal 18ct?
On average, an opal 18ct at 1stDibs sells for $5,932, while they’re typically $585 on the low end and $175,000 for the highest priced versions of this item.
