Certified Opal For Sale on 1stDibs

On 1stDibs, you can find the most appropriate certified opal for your needs in our varied inventory. Frequently made of Gold, Platinum and 18k Gold, this item was constructed with great care. You can easily find a 22 antique edition and 44 modern creations to choose from as well. Making the right choice when shopping for a certified opal 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. There have been many well-made iterations of the classic certified opal over the years, but those made by Malpani Jewels, Merkaba and Tamir are often thought to be among the most beautiful. While most can agree that any certified opal from our collection can easily elevate most outfits, but the choice of a Diamond version from the 50 available is guaranteed to add a special touch to your ensemble. See these pages for an oval cut iteration of this accessory, while there are also cabochon cut and round cut cut versions available here, too. There aren’t many items for men if you’re seeking a certified opal, as most of the options available are for women and unisex.

How Much is a Certified Opal?

Prices for a certified opal can differ depending upon size, time period and other attributes — at 1stDibs, these accessories begin at $599 and can go as high as $120,000, while this accessory, on average, fetches $10,000.
