12 Ct Ruby For Sale on 1stDibs

On 1stDibs, you can find the most appropriate 12 ct ruby for your needs in our varied inventory. Each design created in this style — which was crafted with great care and often made from gold, 18k gold and yellow gold — can elevate any look. In our selection of items, you can find a vintage example as well as a contemporary version. If you’re looking for a 12 ct ruby from a specific time period, our collection is diverse and broad-ranging, and you’ll find at least one that dates back to the 18th Century while another version may have been produced as recently as the 21st Century. A 12 ct ruby from LB Exclusive, Daizy Jewellery and VR Jewels — each of whom created a beautiful version of this treasured accessory — is worth considering. A 12 ct ruby of any era or style can lend versatility to your look, but a version featuring diamond, from our inventory of 278, is particularly popular. A round cut version of this piece has appeal, but there are also oval cut and mixed cut versions for sale. When shopping for a 12 ct ruby, you’ll find that there are less available pieces for unisex or men today than there are for women.

How Much is a 12 Ct Ruby?

On average, a 12 ct ruby at 1stDibs sells for $2,475, while they’re typically $1 on the low end and $4,968,880 for the highest priced versions of this item.
