1.59 Ct. Greenish Blue Sapphire from Madagascar

This 1.59 carat oval shape greenish blue sapphire measures 7.49 x 6.41 x 4.21 mm, offering a classic oval profile that flatters most finger shapes and settings. The mixed brilliant cut balances the pavilion and crown faceting to create lively scintillation, with an excellent polish that enhances surface reflection and provides a smooth, satiny finish. Color is one of the defining attributes of this stone, displaying vivid color intensity that sits in the attractive zone between green and blue, a hue that reads as sophisticated and contemporary while retaining the traditional appeal of sapphire. The transparency is excellent, and the clarity has been assessed as slightly included evaluated at eye level, meaning minor natural inclusions are present but do not detract from the gem when set, and they often help to confirm natural origin.

From a gemological perspective this sapphire presents a strong value proposition for an informed buyer. It originates from Madagascar, a source known for producing strong, saturated sapphires with appealing regional character, and the stone has been heat treated, a widely accepted and stable enhancement that improves color and clarity without compromising durability. The mixed brilliant cut maximizes brilliance and distributes color evenly across the table, and the 1.59 carat weight in this size range offers an excellent balance of presence and wearability. Polishing quality is excellent, which contributes to the stone sitting prominently in a setting and reflecting light cleanly. The clarity of slightly included evaluated at eye level means that while microscopic and some minor visible inclusions exist, they do not significantly impact light performance or the overall visual appeal for an engagement piece.

For an engagement ring this sapphire is an outstanding option for someone seeking durability, beauty, and a more distinctive hue than traditional blue alone. Sapphires score high on the Mohs hardness scale, making them suitable for daily wear, and the vivid greenish blue color provides a unique, modern look that still reads as classic and timeless. The dimensions and oval outline make it versatile for solitaire, halo, or three stone settings, and the mixed brilliant cut ensures lively sparkle that complements diamond accents. At The Natural Sapphire Company we emphasize accurate grading, honest disclosure of treatments, and careful selection of gemstones for engagement use, and this 1.59 carat Madagascar sapphire exemplifies those priorities, offering a combination of color, cut, and clarity that will serve as a meaningful and enduring symbol of commitment.
