Part of $2.8 Million McLean Mansion Luxury Downsizing Auction (timed auction by Prime Auction Solutions)

Status: Sold

Opal 4cts; diamond .20cts; tourmaline .50cts; 14kt ring; 10.5 grams A bold, modernist cocktail ring centering an oval cabochon opal of approximately 4.00 carats, displaying the milky-white body with shifting flashes of green, pink, and golden play-of-color that defines fine precious opal. The stone is bezel-set in a heavy gold collar that protects its delicate edges while showcasing the ever-changing fire across the dome. Flanking the central opal are two cabochon pink tourmalines totaling approximately 0.50 carats, set horizontally on the shoulders to create a striking lateral axis of color. Between the opal and each tourmaline, vertical bars of pavé-set round diamonds — totaling approximately 0.20 carats — bridge the stones with crisp white sparkle, framing the central gem with architectural precision. Combined gemstone weight is approximately 4.70 carats. Crafted in solid 14-karat yellow gold and weighing a substantial 10.5 grams, the ring has a sculptural East-West orientation with a high, squared bezel and a smooth, rounded shank that tapers comfortably to the finger. The geometry is distinctly modernist — clean lines, strong proportions, and a confident use of color contrast that recalls the artist-jeweler designs of the 1980s and 1990s. A wearable conversation piece for collectors who favor distinctive, gallery-worthy jewelry. Center stone: Oval cabochon opal, approx. 4.00 cts.
