Estate GIA-Certified No-Heat Cabochon Ruby & Diamond Ring | 10.00ct Ruby | 18k Yellow Gold | Size 7

A 10.00-carat natural cabochon ruby takes center stage in this exceptional ring, its smooth domed surface allowing the stone’s natural color and saturation to speak with quiet authority. GIA certified as untreated with no heat or enhancement, this ruby carries the documented rarity that serious colored-gemstone collectors seek.

A luminous halo of 22 natural round brilliant-cut diamonds swirls around the ruby, adding flashes of contrast and light while preserving the center stone’s commanding presence. The balanced halo design gives the ring a refined finish without competing with the ruby’s organic cabochon character.

Set in 18k yellow gold and weighing 17.3 grams, the ring has the substantial construction this remarkable gemstone deserves. In pre-owned, very good condition and finished in a classic size 7, it is a distinctive statement jewel with enduring collector appeal.
