Art Deco Harlequin Precious Black Opal Baguette Diamond Engagement Ring Platinum

About the Item

Art Deco Australian Lightning Ridge Harlequin precious black opal and baguette-cut diamond engagement or cocktail ring in platinum, circa 1930, probably American. This ring features a rare natural and solid precious black opal which exuberates rarity and brilliance: its symmetrical oval shape and dark bodycolor set the stage for it to display every color of the rainbow, red being the rarest and the most evident one in this jewel, in a desirable mix of harlequin and pinfire patterns. This gemstone is claw-set to the center and accented with two baguette-cut diamonds on each shoulder, flowing through to a solid D-shape platinum shank. Central black opal: estimated 5.0ct (approximately 15.32 x 11.35 x 5.14 mm); harlequin and pinfire play-of-color phenomenal pattern. Diamonds: 4 baguette-cut; estimated 0.30ct in total. Shanked marked “PLAT” for platinum. Finger size: 51 (EU), but it can be sized up or down. Gross weight: 4.15g. The central gemstone is an Australian fine black opal from Lightning Ridge in New South Wales, Australia. Their distinctive quality is their "play of color," a phenomenon which manifests in opals' colors, shifting and changing as the gems move. Australian opals, in general, are the quality benchmark in the world family of opals owing to their durability and beauty. This particular opal is outstanding for its particularly broad range of the rainbow colors it exhibits (from vivid red to intense yellow, orange, green, blue, violet, purple and pink), the defined patterns exhibited (this opal is particularly unusual for its large, rolling flashes of red, which is the rarest color in opal, and also for the patchwork pattern in which these different colors of the rainbow appear, reminiscent of the most highly-valued Harlequin opals) and its brightness. Given the rarity of gathering all these factors in a single opal, this could be easily defined as a one-of-a-kind piece of jewelry with unique beauty. This item is in good condition, with marks and scratches consistent with general age and wear. Antique, period and vintage pieces, both signed and unsigned, are being offered as worn.
