Vintage 10K Gold Natural Blue Star Sapphire & Diamond Gentleman’s Ring 

A striking and collectible vintage star sapphire ring with substantial presence, classic craftsmanship, and authentic natural gemstone character

Bold and substantial, this vintage 10K gold gentleman’s ring showcases a natural blue star sapphire cabochon displaying a visible six-ray asterism. The sapphire measures approximately 8 x 10mm, has a dome shape, and is estimated to weigh approximately 4–6 carats. Due to the closed back setting, an exact weight is unable to be determined. Its richly saturated deep blue color and luminous moving star effect create striking visual presence under direct light. 

The sculptural mounting is accented by two natural round brilliant-cut diamonds recessed into geometric yellow and white gold shoulder settings, adding subtle brilliance and refined contrast. Crafted with impressive weight and strong architectural styling, this ring embodies classic late-20th-century masculine luxury design.
