2.54 Ct. Alexandrite from Tanzania

This 2.54 carat cushion shape alexandrite from Tanzania is presented by The Natural Gemstone Company with exacting technical specifications for the discerning buyer. The gem measures 8.64 by 7.18 by 4.16 mm, and it is cut in a mixed brilliant style, combining a brilliant facet configuration on the crown with carefully modified pavilion faceting to balance scintillation and color saturation. The mixed brilliant approach concentrates light return into the table and crown facets while preserving internal color zoning, which is critical for alexandrite to exhibit its characteristic color change. This specimen shows a clear transition from green in daylight to purplish red under incandescent lighting, with an intense color intensity in both states, and the change is well defined across the stone. Clarity is graded as very slightly included at eye level, with minute internal features that do not materially interrupt the clean visual planes or the gem’s transparency. The polish is excellent, the facet junctions are crisp, and the overall symmetry and pavilion angles are executed to optimize both brilliance and chromatic response, making this alexandrite an exceptional candidate for a ring or pendant where light interaction will be dynamic.

Ethical sourcing is central to the value proposition of this alexandrite, and The Natural Gemstone Company maintains a documented chain of custody from Tanzania to our workshops, with sourcing partners who follow responsible mining practices and community supportive measures. No enhancement has been applied to this stone, the color and clarity are entirely natural, and the absence of treatments preserves both the gem’s integrity and long term stability. For the conscious consumer, this alexandrite represents a convergence of technical quality and ethical consideration, it provides a rare color change in a market where untreated material of this size is uncommon, and its traceable origin and partner relationships reduce the risk of opaque supply chains. This gem suits a collection focused on natural, investment quality gemstones that combine demonstrable craftsmanship in cutting, proven optical performance, and a sourcing story that aligns with sustainable and fair practice principles.
