2.12 Ct. Alexandrite from Ceylon (Sri Lanka)

This 2.12 carat cushion shape alexandrite measures 8.17 x 7.54 x 3.82 mm, and presents a transparent body with an intense color intensity and a mixed brilliant cut. The gem is graded as very very slightly included at eye level, indicating exceptional apparent clarity for its size, and it has been given an excellent polish that enhances facet definition and surface luster. Originating from Ceylon Sri Lanka, this stone carries the geological character associated with that locality, and it is offered in its natural state with no enhancement. The cushion shape coupled with the mixed brilliant faceting balances broad color display and scintillation, producing a substantial presence in both mounted and loose settings. The Natural Gemstone Company offers this piece with full disclosure of its physical and optical properties, emphasizing the gemological attributes rather than speculative descriptors.

Under daylight and natural northern light the stone leans toward a greenish tone, exhibiting a saturated, intense green that reads as cool and verdant, while the mixed brilliant cut returns crisp, white brilliance across the table and crown facets. Under incandescent and warm tungsten sources the alexandrite shifts toward orangish hues, the body color warming to rich, saturated tones, and the stone displays increased red and orange responses that complement its cushion outline. Under LED sources the reaction depends on the LED color temperature, with cooler white LEDs maintaining more greenish aspects, and warmer LEDs promoting the orangish side, while the strong polish sustains scintillation. In fluorescent lighting the stone can appear intermediate between the two states, with balanced green to orangish tones and steady brilliance. In low ambient light and candlelight the gem intensifies its color change effect, the orangish tones becoming pronounced and the mixed brilliant cut producing lively flashes and localized fire. The very very slightly included clarity grade means that inclusions remain minimal to the unaided eye, allowing light to travel through the pavilion and crown with limited interruption, preserving both color change and facet sparkle. This alexandrite combines provenance, natural untreated status, fine polish, and robust optical performance, qualities documented and presented by The Natural Gemstone Company.
