0.64 Ct. Bluish Green Sapphire from Madagascar

If you are searching for the perfect stone to end your quest for an engagement ring that feels both timeless and unmistakably personal, this sapphire from The Natural Sapphire Company answers that need. This transparent bluish green sapphire weighs 0.64 carat, and measures 4.94 x 4.93 x 3.37 mm, offering a compact yet meaningful presence that sits beautifully in a variety of settings. Its round shape and mixed brilliant cut honor classic form while introducing modern fire, and its clarity grade slightly included evaluated at eye level ensures that the gem is both natural and luminous. The color reads as medium intense bluish green, a tone that is distinct without overwhelming, and it has received a heat treatment enhancement to stabilize and enrich the hue, a common and accepted practice that elevates the stone without diminishing its natural character. Finished with an excellent polish, this sapphire presents a refined surface that interacts with light in a way few stones can match.

What truly sets this gem apart is how its structure creates a sparkle that feels uniquely alive. The mixed brilliant cut blends small, precise crown facets with a finely proportioned pavilion, a combination that is engineered to maximize light return and internal reflection. As white light enters the crown, it meets alternating planes of brilliance and contrast that break the light into flashes and pinpoints. The gem refracts and disperses light according to its high refractive index, while subtle pleochroic behavior allows bluish and green tones to appear differently as the stone moves, giving a dynamic, shifting color story. The depth of 3.37 mm and the near round symmetry at 4.94 x 4.93 mm create the right balance between table size and pavilion depth, so that much of the entering light is bent back through the crown rather than lost through the pavilion. Slight inclusions, visible at eye level but not distracting, can act like tiny mirrors, catching light and adding scintillation rather than dulling it, which results in a lively, multifaceted sparkle that changes with the smallest motion.

For collectors who treasure origin and story, and for couples seeking a singular engagement gem, this Madagascar sapphire occupies the sweet spot of rarity, wearability, and beauty. Madagascar is known for producing sapphires with finely nuanced color, and this stone carries that provenance in its tone and character. The excellent polish ensures that every facet edge is crisp, maximizing the starburst of light and minimizing surface haze, which is essential for daily wear and for settings that frame the sapphire closely. Because it is heat treated, the color is more stable and wearable over time, and because of its moderate size and round form, it adapts gracefully to solitaire, halo, three stone, or bezel settings. At The Natural Sapphire Company we understand that your search is about more than measurements and clarity grades, it is about the feeling a stone evokes when held up to light, and this sapphire answers that call with confidence. If your aim is to find a gem that settles the search and becomes a story you return to every day, this Madagascar bluish green sapphire is an exceptional choice.
