40 Ct For Sale on 1stDibs

Find the exact 40 ct you’re shopping for in the variety available on 1stDibs. Frequently made of Gold, 18k Gold and White Gold, this item was constructed with great care. Our collection of these items for sale includes 67 vintage editions and 60 modern creations to choose from as well. Making the right choice when shopping for a 40 ct 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. For this particular piece, .5 Carat and 1 Carat are consistently popular carat weights. Finding an appealing 40 ct — no matter the origin — is easy, but LB Exclusive, Sarosi By Timeless Gems and Bvlgari each produced a popular version that is worth a look. A 40 ct of any era or style can lend versatility to your look, but a version featuring Diamond, from our inventory of 89, is particularly popular. Today, if you’re looking for a round cut version of this piece and are unable to find the perfect match, our selection also includes oval cut and emerald cut alternatives. When shopping for a 40 ct, you’ll find that there are less available pieces for unisex or men today than there are for women.

How Much is a 40 Ct?

The price for a 40 ct starts at $144 and tops out at $109,500 with these rings, on average, selling for $3,650.
