4.52 Ct. Blue Sapphire from Madagascar

You have been searching for a sapphire that balances rarity, beauty, and wearable size, and this cushion shape blue sapphire answers that search with quiet confidence. We present a transparent 4.52 carat cushion shape sapphire measuring 9.44 by 7.42 by 6.45 mm, cut in a refined mixed brilliant cut that brings together classic cushion proportions and modern faceting precision, vivid color intensity and an excellent polish that together create a gem ready to become the focal point of an engagement ring, a statement pendant, or a treasured collecting piece. The stone is heat treated, a widely accepted enhancement that stabilizes and intensifies the rich blue hue, and it originates from Madagascar, a source increasingly prized for sapphires with clarity and color that rival the finest historical examples. At eye level this sapphire is graded as very slightly included, a clarity tier that assures you of a clean, luminous appearance in everyday wear while preserving the natural character that collectors value. The overall presentation is one of immediate impact paired with refined detail, a gem that looks larger and more luminous than its carat weight might suggest, ideal for anyone who wants a sapphire that serves as both a symbol and an heirloom.

The geometric faceting of this mixed brilliant cut is the heart of its visual magic, crafted to allow maximum light play across every facet, every plane, and through every curve of the cushion outline. The pavilion facets work in concert with the crown arrangement to capture light and return it as deep blue flashes, lively scintillation, and the kind of even tone that keeps the eye moving, revealing different layers of blue from cornflower to royal depending on angle and light source. The cushion silhouette softens the geometry and gives the mixed brilliant cut room to breathe, while the precision of the facet junctions and the excellent polish ensure that light travels unimpeded, creating a lively interplay between brilliance and depth. Because the cutter has balanced the size of the table, the depth, and the facet angles, the result is a gem that balances bright returns with saturated color, a sapphire that glows from within when viewed face up, and that displays an elegant pattern of light when tilted. For those who appreciate the science behind beauty, this is a stone where optical design and artisanal skill meet, producing a performance that rewards close inspection and that shines unmistakably from across the room.
