0.84 Ct. Alexandrite from Brazil

This alexandrite is a transparent, 0.84 carat, oval shape gemstone, with precise dimensions of 6.02 by 4.74 by 3.98 millimeters, cut in a faceted style with a mixed brilliant arrangement to balance scintillation and color saturation. The clarity has been evaluated at eye level as very slightly included, a grade that permits clean visual appeal while preserving natural character. Color intensity is described as intense, exhibiting a classic alexandrite color change from a greenish hue under cooler, fluorescent daylight to a purplish tone under warmer, incandescent illumination, a response that is readily observed in photographs and in hand. The polish is excellent, which enhances the stone’s surface luster and facet definition, and there are no enhancements, a condition that confirms the gem’s natural state and supports its long term value and stability.

Geologically, this specimen is a true alexandrite from Brazil, with the chromium driven color change that defines the variety, and it is a member of the chrysoberyl family, known for its compact crystal structure and lasting resilience. Alexandrite typically rates 8.5 on the Mohs hardness scale, which provides strong resistance to wear and abrasion compared to many other gem materials, a property that supports frequent wear when properly set and cared for. The mixed brilliant cut used on this stone has been chosen to reconcile color depth with light return, preserving the gem’s color change while providing lively facet play, and the excellent polish ensures minimal light scattering at the surface, which keeps the perceived color and brilliance true.

As a generational heirloom, this alexandrite has multiple attributes that support long term retention and transferability, beginning with its natural color change, which is both an aesthetic signature and a marker of authenticity that is difficult to replicate. The absence of enhancements increases collector confidence, because untreated gemstones are preferred in heirloom contexts for their verifiable provenance and predictable behavior over time. The stone’s size and mixed brilliant cut make it adaptable to a variety of classic settings that emphasize protection as well as aesthetic longevity, for example a low profile bezel or a high quality four prong mounting in a durable metal such as platinum or 18 karat gold, which together minimize exposure to physical stress and maintain the stone’s condition for future generations. The origin from Brazil is an additional provenance note that can be recorded with accompanying documentation, and that provenance can be included in family records to support a story of origin that enhances emotional and monetary value.

To preserve this alexandrite as an heirloom, sensible care and documentation are essential, including a professional appraisal and periodic inspections of the mounting by a qualified jeweler, gentle cleaning with warm soapy water and a soft brush, and avoidance of harsh chemicals or extreme thermal shocks. Design decisions should prioritize structural security, for example choosing a mounting that protects the girdle and pavilion from knocks while allowing the gem’s color change to remain visible during wear, and selecting a setting style that can be reworked by future jewelers if tastes change. The Natural Gemstone Company can provide certification level documentation on request, and we recommend that the gem be accompanied by a written record of its specifications, origin, and treatment status, stored with estate papers. With its intense color change, durable chrysoberyl composition, and unenhanced condition, this 0.84 carat Brazilian alexandrite is well suited to become a meaningful, wearable, and verifiable heirloom that can be responsibly passed from one generation to the next.
