1.59 Ct. Alexandrite from Madagascar

This 1.59 carat cushion shaped alexandrite from Madagascar is presented by The Natural Gemstone Company with precise cutting and documentation, dimensions measure 7.15 by 5.62 by 4.17 millimeters, the gem is fashioned in a mixed brilliant cut combining a faceted crown with a modified pavilion to balance color change performance and light return, the cushion outline with slightly rounded corners yields an elegant face up area that maximizes perceived size for its carat weight, the color shift ranges from yellowish green under certain light sources to reddish green under incandescent or warmer light, the stone exhibits medium color intensity, clarity is evaluated as slightly included at eye level which preserves strong transparency, polish is graded excellent, and there are no enhancements reported.

The mixed brilliant faceting strategy applied to this piece emphasizes small star and kite facets on the crown paired with step influenced pavilion facets to increase internal reflection and support the alexandrite effect, crown angles are optimized to produce scintillation without washing out the subtle color change, pavilion depth and girdle proportions are balanced to avoid windowing while maintaining a lively return of light, the medium color intensity ensures clear dichroism between greenish and warm tones which is desirable in collector grade material, the slightly included clarity grade indicates natural growth features that are visible to a trained eye but do not significantly interrupt the gem s optical flow, these internal characteristics authenticate the natural origin from Madagascar and are consistent with unenhanced alexandrite crystallization.

On the Mohs hardness scale alexandrite sits at approximately 8.5 which places it well above quartz and topaz and slightly below corundum and diamond, to provide perspective diamond rates 10, corundum rates 9, topaz rates 8, and quartz rates 7, this relative hardness indicates excellent resistance to scratching for daily wear in rings and bracelets when properly set, however toughness varies and care should be taken against sharp blows, we recommend secure prong or partial bezel settings to protect the girdle and corners, routine cleaning with warm soapy water and a soft brush is advisable, avoid prolonged exposure to harsh acids or extreme thermal shock, The Natural Gemstone Company stands behind the documented origin and natural, non enhanced status of this alexandrite and can provide additional imaging or mounting recommendations to suit both collectors and bespoke jewelry projects.
