0.68 Ct. Alexandrite from Brazil

This 0.68 carat oval alexandrite from Brazil presents an exceptional combination of natural rarity and gemological quality, offered by The Natural Gemstone Company. Measuring 5.23 x 4.19 x 3.19 mm, the stone is faceted in a mixed brilliant cut that balances scintillation with a broad color face, and it displays intense color change from green in fluorescent and daylight to purple under incandescent lighting. Evaluated as eye clean at eye level, with excellent polish and no enhancements, this specimen meets the criteria sought by educated buyers who prioritize natural origin and optical performance. The intense color change is the primary driver of value in alexandrite, and in this example the chromatic shift is pronounced and even across the table, which indicates well distributed chromium and minimal masking inclusions. The mixed brilliant cut was chosen to optimize both light return and the depth of color apparent face up, and the excellent polish enhances facet crispness and lively scintillation. Brazilian alexandrite is respected for producing clear material with attractive color change, and the combination of eye clean clarity, strong change, and no treatments places this gem in a premium category for collectors and connoisseurs.

When set in jewelry, the green to purple play of color allows versatile and flattering combinations for a range of skin tones. In its green state the stone reads as a cool, verdant hue that pairs exceptionally well with white gold or platinum, enhancing contrast on fair complexions and complementing cool undertones, while yellow gold can introduce warm contrast that makes the green appear more vibrant against warm or olive skin tones. In incandescent light the purple phase becomes dominant and warmer, creating a rich, almost burgundy purple that harmonizes beautifully with rose gold and yellow gold, and provides a dramatic, luminous contrast on medium to deep skin tones. Neutral undertones will find the gem universally flattering, as the color change offers two complementary looks within a single setting. For practical design choices, a well proportioned prong setting will maximize color visibility and sparkle, while a low profile bezel offers security without significantly diminishing the color change. At 0.68 carat the gem is ideal as a refined center in a ring or as a striking pendant, and as a natural, untreated alexandrite from Brazil it represents a durable investment in both aesthetic versatility and rarity, available through The Natural Gemstone Company.
