Diamond Platinum Ring Cushion For Sale on 1stDibs

You are likely to find exactly the diamond platinum ring cushion you’re looking for on 1stDibs, as there is a broad range for sale. Frequently made of Platinum, Gold and 18k Gold, this item was constructed with great care. Our collection of these items for sale includes 909 vintage editions and 1440 modern creations to choose from as well. Making the right choice when shopping for a diamond platinum ring cushion may mean carefully reviewing examples of this item dating from different eras — you can find an early iteration of this piece from the 18th Century and a newer version made as recently as the 21st Century, both of which have proven very popular over the years. As it relates to this specific piece, our collection includes designs that are universally popular, but .5 Carat and 1 Carat carat weights, specifically, are sought with frequency. Finding an appealing diamond platinum ring cushion — no matter the origin — is easy, but J. Birnbach, Tiffany & Co. and Roman Malakov each produced a popular version that is worth a look. A cushion cut version of this piece has appeal, but there are also antique cushion cut and old mine cut versions for sale. When shopping for a diamond platinum ring cushion, you’ll find that there are less available pieces for unisex or men today than there are for women.

How Much is a Diamond Platinum Ring Cushion?

Prices for a diamond platinum ring cushion can differ depending upon size, time period and other attributes — at 1stDibs, these accessories begin at $250 and can go as high as $3,200,000, while this accessory, on average, fetches $21,127.
