Certification: GIA 1493351237

The wide 18K gold band features bold architectural construction with three parallel rows of channel-set diamonds flanking the center ruby. Yellow gold prongs secure the oval cabochon ruby while white gold head and diamond rows create striking color contrast. The substantial 13.82-gram weight delivers impressive heft appropriate for statement jewelry while the wide band provides stability and presence on the finger. High-polish finish on the yellow gold creates lustrous surfaces that complement the ruby's smooth cabochon dome. Six yellow gold prongs hold the ruby securely while allowing light to penetrate the translucent stone. The white gold diamond rows sit flush with the yellow gold band, creating clean geometric lines and Art Deco inspired symmetry.

This 3.93 carat ruby represents exceptional rarity with GIA confirmation of no heat treatment, as over 95 percent of rubies in the market receive heat enhancement. The purplish red color combines the classic ruby hue with violet undertones that add depth and richness to the stone's appearance. Oval double cabochon cutting features smooth domed surfaces on both crown and pavilion, maximizing the ruby's color saturation and translucent quality while creating larger apparent size. Measuring nearly 10mm in length, this ruby delivers substantial visual presence on the finger. The translucent clarity allows light to pass through the stone while natural inclusions create the characteristic appearance of fine rubies. GIA certification confirms natural origin and absence of heat treatment, significantly enhancing the stone's value and collectability. Unheated rubies command premium prices due to their scarcity and natural beauty. For serious colored gemstone collectors, unheated rubies represent the pinnacle of corundum collecting, combining natural rarity with timeless appeal.
