3.64 Ct. Blue Sapphire from Madagascar

This 3.64 carat oval blue sapphire is an exceptional example of Madagascar origin material, with precise dimensions of 9.93 by 8.51 by 5.46 mm, a mixed brilliant cut, and a face up presentation that speaks to both depth of color and fine cutting skill. The stone is transparent and graded eye clean at typical viewing distance, meaning no inclusions are visible to the unaided eye, a quality highly prized by discerning buyers. Its vivid color intensity is classic for premium blue sapphires, exhibiting a saturated yet balanced blue that reads richly in both daylight and artificial lighting. The excellent polish ensures that each facet boundary is crisp, allowing for strong light return and crisp facet contrast. This sapphire has been heat treated, a widely accepted and stable enhancement for sapphires that improves color and clarity while being fully disclosed, and its combination of natural origin, professional treatment, and superior finishing places it solidly in the market for collectors and fine jewelry commissions.

From every angle this sapphire shows why flawless presentation matters, the eye clean clarity allows unfettered light travel through the gem, producing strong scintillation from the mixed brilliant faceting and a velvety, deep blue when viewed face up. The mixed brilliant cut balances large crown facets to showcase color, with pavilion facets that deliver lively brilliance and controlled light leakage, so the stone appears larger and more vivid than its carat weight alone might suggest. The excellent polish enhances facet brightness and overall sparkle, so the gem catches and returns light consistently as it is turned, making it an ideal centerpiece for a ring or bespoke setting that will be seen in motion. For the educated buyer considering longevity and value, this sapphire combines reliable provenance from Madagascar, meticulous cutting, and full disclosure of heat treatment, qualities that The Natural Sapphire Company documents and stands behind. If you are planning a custom mounting or an investment grade purchase, this sapphire offers immediate visual impact, a strong profile for resale or upgrade, and the sort of classic beauty that rewards both daily wear and long term appreciation.
