1.59 Ct. Blue Sapphire from Australia

One beautiful transparent 1.59 carat marquise shape blue sapphire from The Natural Sapphire Company presents an opportunity to own a truly rare jewel, a stone whose elongated silhouette and mixed brilliant cut have been fashioned to maximize depth and fire. This particular gem measures 13.73 x 4.73 x 2.97 mm, and its dark color intensity is a dramatic, velvety blue that reads as both regal and modern, an ideal centerpiece for a bespoke commission or an exclusive limited edition piece. The clarity is graded as very slightly included when evaluated at eye level, ensuring a clean face up appearance with character that confirms natural origin, while the excellent polish allows light to glide across the facets for a silky, luminous finish. Originating from Australia and enhanced by traditional heat treatment, this sapphire benefits from a stable and industry accepted enhancement that deepens its tone without compromising its integrity, making it a jewel that wears like a treasure and lives like an heirloom.

Durability is at the heart of what makes this marquise sapphire perfect for daily wear, corundum ranks at nine on the Mohs scale, second only to diamond, which gives it exceptional resistance to scratching and everyday abrasion. The marquise form does present delicate points, and our craftsmen recommend protective settings such as low bezels or reinforced prongs to preserve the sharp terminations and to avoid catching during active wear, guidance we provide with every bespoke commission. Heat treatment is permanent under normal conditions, and the excellent polish and stable crystal structure mean the stone will retain its brilliance through years of daily use, provided it receives routine care and periodic setting inspection. When set thoughtfully, this Australian marquise sapphire becomes an effortless daily companion, a discreet signal of curated taste and membership in an exclusive circle of collectors who value rarity and resilience, a promise of enduring beauty from The Natural Sapphire Company.
