0.43 Ct. Green Sapphire from Madagascar

You have a clear vision for the perfect gemstone, whether you are imagining an engagement ring that speaks of individuality and enduring love, or you are a collector seeking a rare tone and quality to add to a curated collection, and this 0.43 carat green sapphire answers that need with quiet confidence. This oval shaped gem measures 5.30 by 3.70 by 2.62 millimeters, and its mixed brilliant cut delivers lively scintillation while preserving a flattering outline that sits beautifully in both classic and contemporary settings. At eye level the clarity reads very very slightly included, which means the stone appears transparent and clean to the viewer, and its medium color intensity gives it a fresh, natural green that adapts to different lighting without becoming flat or overpowering. The polish is excellent, so the facets catch light with crisp reflections, and the heat treatment enhancement is a standard, stable process that enriches the color and clarity while keeping the sapphire natural at its core. When you seek a gemstone that combines wearability, refinement, and a story of origin, this Madagascar sapphire is an elegant solution.

Imagine the first chapter of this stone in the highlands and riverbeds of Madagascar, where mineral rich formations yield sapphires that often surprise with uncommon hues. Local miners, working with a mix of traditional knowledge and careful modern methods, recovered this rough crystal from alluvial deposits, recognizing its promise in a parcel that mixed everyday material with jewels of distinction. Early sorting is crucial, and the rough was evaluated for color potential, clarity, and crystal form. That initial judgment guided the choice to move this piece into a selective faceting program rather than into mass production. Responsible sourcing matters to you, and to us at The Natural Sapphire Company, so we trace the path of each gem from the field to ensure that the people and the environment involved are respected, and that the rough selected has the best potential to become a gem you will cherish.

The journey from rough to polished gem is where character and value are truly shaped, and for this oval green sapphire the decision to employ a mixed brilliant cut was deliberate. A mixed brilliant cut gives you the flash associated with brilliant facets on the crown, while the pavilion facets are arranged to enhance depth and color dispersion, resulting in a gem that reads lively face up yet retains a graceful profile when set in jewelry. The cutter calibrated the pavilion angles and table size to balance light return and color strength, mindful of the sapphire’s medium color intensity so that the green remains fresh and not overly deep. The stone underwent a controlled heat treatment to improve color uniformity and reduce the visibility of minor inclusions, and then an exacting polish delivered the excellent surface finish you see. The very very slightly included clarity grade evaluated at eye level means that inclusions are minimal and do not distract from the gem’s presence, making this sapphire suitable for both an intimate everyday ring and a treasured collectible piece. The precise dimensions, 5.30 by 3.70 by 2.62 millimeters, make it versatile for a variety of mounting styles, from a delicate vintage halo to a modern bezel that showcases its pure oval silhouette.
