7.12 ct Unheated Blue Sapphire — Collector Grade
A gem for the connoisseur — a 7.12-carat unheated sapphire of exceptional pedigree and commanding presence. This cushion-cut stone displays a luminous interplay of midnight and cornflower blues, with flashes of steel and silver that shift effortlessly beneath light. Its color is entirely natural — no heat, no enhancement — the result of profound metamorphic forces deep within the Earth’s crust, crystallized over millions of years under immense pressure and temperature.
Certified by AIGS (Report GF25090137) as Natural Sapphire — No Indication of Heat Treatment, this piece ranks among the rarest of fine gemstones. Fewer than one in a thousand gem-quality sapphires remain in this pristine, untreated state — a level of authenticity sought only by the most discerning collectors and investors.
Every facet has been precision-cut to maximize brilliance and depth, balancing geometry and fire in a way few sapphires achieve. Its transparency, saturation, and polish reveal a perfect harmony of nature and craftsmanship — the hallmarks of a world-class specimen.
This sapphire embodies permanence — a tangible store of beauty, rarity, and value destined for fine bespoke jewelry or long-term private collection.
