0.61 Ct. Alexandrite from Brazil

Presented here by The Natural Gemstone Company is a transparent oval alexandrite weighing 0.61 carat, a gem that embodies premium quality through its measured weight, precise proportions, and vivid color change. The gem measures 6.30 x 4.56 x 2.87 mm, dimensions that deliver a balanced face up presence and efficient use of material, attributes that are particularly important for alexandrite where scarcity and color quality are defining factors. This piece exhibits a clear and distinct transition from green under fluorescent lighting to purple under incandescent lighting, a hallmark of classic alexandrite behavior with vivid color intensity that remains saturated across viewing conditions. Originating from Brazil, the stone is natural and has no enhancement, which preserves its intrinsic characteristics and long term stability. At 0.61 carat this alexandrite occupies a noteworthy position in the market, where per carat rarity can escalate quickly for well colored material, making this size attractive for clients seeking a premium color change specimen that remains wearable and versatile.

The cutting style is a mixed brilliant cut, combining faceting techniques that enhance scintillation while preserving internal color depth, and the cutting execution is reflected in an excellent polish that promotes crisp facet definition and efficient light return. Measured depth of 2.87 mm relative to the average diameter of 5.43 mm produces an overall depth proportion of approximately 53 percent, a proportion that supports both face up spread and internal color saturation rather than a shallow appearance that would dilute color. Clarity is graded as slightly included at eye level, indicating small natural inclusions that do not detract from overall appearance and that often serve as indicators of natural origin during professional assessment. The combination of a well executed mixed brilliant cut, excellent polish, and eye level clarity produces strong optical performance and a vivid display of color change, attributes that define premium alexandrite quality beyond simple weight alone.

From a practical perspective this 0.61 carat alexandrite is well suited to refined jewelry applications where color change and optical distinctiveness are priorities. The oval outline works effectively for solitaire rings, pendants, and bespoke settings, and the stone can be secured in a bezel or a minimal prong setting to protect the girdle while allowing for optimal light interaction. Given the gem is natural and untreated, a formal gemological report is recommended for documentation, insurance, and future appraisal, and The Natural Gemstone Company can advise on laboratory options and appropriate mounting specifications. Care recommendations include routine cleaning with mild soap and water, avoidance of harsh chemicals and unadvised ultrasonic cleaning, and periodic inspection of the setting to prevent impact related damage. The 0.61 carat weight, combined with vivid color change, a balanced mixed brilliant cut, and excellent polish, establishes this alexandrite as a premium quality gem, suitable for collectors and designers seeking a stable, natural color change stone with proven visual appeal.
