0.93 Ct. Alexandrite from Ceylon (Sri Lanka)

This Other certified, color change alexandrite weighs 0.93 carat, with precise dimensions of 10.13 x 5.03 x 1.75 mm, presented in a deliberate fancy outline and executed as a step cut. The pavilion and crown planes are broad and controlled, designed to emphasize large color fields rather than scintillation, which suits alexandrite where color change is the primary attribute. Under fluorescent or daylight balanced lighting the stone exhibits a yellowish green tone, while under incandescent lighting it shifts to a brownish orange, demonstrating an intense color intensity that reads consistently across the table and facets. Clarity is graded as very very slightly included when evaluated at eye level, inclusions are minimal and well positioned, they do not interrupt the color zoning or the overall transparency, and the excellent polish delivers clean facet junctions and crisp facet reflections. Origin is Ceylon, Sri Lanka, enhancement none, and the gem has been certified for its color change properties, a combination that speaks to both provenance and natural integrity. The geometric step faceting reduces light leakage, stabilizes the visible color effect, and allows a lapidary to present a larger apparent surface area, which is particularly valuable for a subcarat alexandrite where optical presence is paramount.

For a buyer seeking an heirloom quality piece, this alexandrite has the technical characteristics that support longevity and intergenerational desirability. Alexandrite is a hard gem with excellent structural stability, and with no treatments, the stone retains original material properties, which simplifies conservation for future custodians. The combination of a durable step cut, an excellent polish, and a documented Ceylon origin ensures resilience against wear and ease of maintenance, provided conventional care is observed. A protective mounting, such as a bezel or a low profile gallery, will preserve the unique facet edges and minimize prong impact, while allowing the color change to be read in everyday lighting conditions. The distinctive fancy shape and measured dimensions make this gem ideal as a bespoke center stone for a signet, a classic right hand ring, or a pendant intended to be handed down, because its visual personality will remain unmistakable across generations. The Natural Gemstone Company provides the accompanying certification and condition documentation, which enhances traceability and estate value, making this alexandrite not only a rare optical phenomenon, but a technically sound candidate for a true family heirloom.
