0.66 Ct. Bluish Green Sapphire from Madagascar

This exquisite example from The Natural Sapphire Company is a 0.66 carat round bluish green sapphire, a gem whose weight alone announces its premium quality and enduring presence. At 4.84 x 4.78 x 3.80 mm, this stone occupies the ideal intersection of wearable elegance and visible impact, offering a face up presence that belies its modest dimensions while delivering the substance that connoisseurs prize. The mixed brilliant cut has been executed with discipline and eye to light performance, resulting in a lively play of scintillation across the table and crown, while the excellent polish ensures that every facet edge returns light with clarity and precision. Transparency is superb, and the clarity grade is described as very very slightly included when evaluated at eye level, a statement that means the stone reads clean to the beholder and carries the kind of internal whisper of character that true collectors appreciate. Color sits in the medium intense range, a rare and refined bluish green that reads sophisticated rather than loud, a hue that will harmonize with precious metals and bespoke settings alike. Heat treatment has been applied, a standard and stable enhancement that brings out the best in naturally occurring color, and the sapphire hails from Madagascar, a region celebrated for producing stones with distinct personality and minerality.

The 0.66 carat weight gives this round mixed brilliant sapphire an authoritative presence on the hand, the kind of presence that signals discerning taste without ostentation. Carat weight is not merely a number, it is a measure of substance, of rarity, and of the emotional weight a gem will carry through a lifetime, and at two thirds of a carat this sapphire finds an arresting balance. The mixed brilliant cut maximizes return of light from the pavilion while preserving a generous table, a combination that allows the bluish green color to breathe, to reveal undertones and depth as the gem moves. The eye level clarity assessment of very very slightly included means that the inclusions are delicate and do not interrupt the visual symphony of color and fire, while the excellent polish soothes every transition between facets, producing reflections that are crisp and layered. In practical terms this weight and cut make the sapphire an exceptional choice for an engagement jewel that will be admired for its elegance, for a bespoke ring where proportion and light are as important as carat count, and for a collector who values a gem with refined presence rather than mere size.
