At 6.65 carats this sapphire offers a substantial and collectible weight, matched by precise proportions of 10.10 by 10.09 by 7.11 millimeters, dimensions that provide a commanding yet elegant profile for both display and wear. The stone is transparent, with an eye clean clarity when evaluated at eye level, allowing uninterrupted appreciation of its vivid color intensity. The Asscher cut, with its stepped facets and octagonal silhouette, lends this sapphire a composed brilliance, directing light inward to produce a luminous inner glow rather than fleeting surface sparkle. An excellent polish ensures the facets fall away crisply, accentuating the stones architecture and creating mirror like planes that draw the eye into the heart of the gem. Heat treatment has been applied, a respected and widely accepted enhancement that deepens the stones natural hue and stabilizes its visual balance, revealing the most compelling expression of its greenish blue character.

For the discerning buyer, the applied heat treatment is transparent, documented, and consistent with long standing lapidary practice, allowing the sapphire to present its most arresting hue while retaining its natural structure and character. Whether set into a classic solitaire, framed by a halo of diamonds in a period inspired mount, or kept as a standalone specimen within a curated cabinet, this gem adapts gracefully to designs that emphasize heritage, restraint, and architectural beauty.
