Gia Certified 1 Carat For Sale on 1stDibs
You are likely to find exactly the gia certified 1 carat you’re looking for on 1stDibs, as there is a broad range for sale. Every item for sale was constructed with extraordinary care, often using Gold, 18k Gold and White Gold. In our selection of items, you can find a vintage example as well as a contemporary version. Making the right choice when shopping for a gia certified 1 carat 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. For this particular piece, .5 Carat and 1 Carat are consistently popular carat weights. A gia certified 1 carat from Antinori Fine Jewels, Roman Malakov and Peter Suchy — each of whom created a beautiful version of this treasured accessory — is worth considering. A round cut version of this piece has appeal, but there are also oval cut and cushion cut versions for sale. When shopping for a gia certified 1 carat, you’ll find that there are less available pieces for unisex or men today than there are for women.
How Much is a Gia Certified 1 Carat?
On average, a gia certified 1 carat at 1stDibs sells for $23,202, while they’re typically $100 on the low end and $475,940,000 for the highest priced versions of this item.
