20 Ct For Sale on 1stDibs
On 1stDibs, you can find the most appropriate 20 ct for your needs in our varied inventory. Frequently made of Gold, Yellow Gold and 18k Gold, this item was constructed with great care. Our collection of these items for sale includes 1068 vintage editions and 187 modern creations to choose from as well. Making the right choice when shopping for a 20 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. 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. Creating a 20 ct has been a part of the legacy of many jewelers, but those produced by Tiffany & Co., LB Exclusive and Natkina are consistently popular. While most can agree that any 20 ct from our collection can easily elevate most outfits, but the choice of a Diamond version from the 976 available is guaranteed to add a special touch to your ensemble. A round cut version of this piece has appeal, but there are also oval cut and emerald cut versions for sale. When shopping for a 20 ct, you’ll find that there are less available pieces for unisex or men today than there are for women.
How Much is a 20 Ct?
The price for a 20 ct starts at $50 and tops out at $4,450,000 with these rings, on average, selling for $3,987.
