1.87 Ct. Alexandrite from Ceylon (Sri Lanka)

If you have been searching for a gemstone that ends the quest for a one of a kind engagement stone or a rare addition to a collector cabinet, this transparent 1.87 carat trillion shape alexandrite from Ceylon is the answer. Sourced and presented by The Natural Gemstone Company, this gem measures 6.39 x 7.14 x 5.55 mm, carries a clarity grade of slightly included at eye level, and displays an intense color intensity with an excellent polish. The trillion cut gives the piece a modern triangular silhouette that catches light in a lively, multifaceted way, while the natural, unenhanced state ensures that what you see is the gem itself, not a laboratory treatment. For someone seeking a personal and meaningful center stone, the color changing personality of this alexandrite, moving from yellowish green to reddish green under different lights, makes every moment a scene of discovery and delight.

The visual performance of this Ceylon alexandrite is a daily theater of color and reflection, with fluorescent and daylight leaning to a clear yellowish green, and incandescent or warm light revealing the richer reddish green notes. The intense color intensity is supported by excellent polish and well executed facets, which together maximize the return of light to the eye, giving a lively sparkle despite natural inclusions that are visible only upon close inspection. The trillion cut amplifies the color play along its three corners, producing flashes of warm and cool tones with each turn. For engagement pieces where the wearer moves through varied lighting situations, or for collectors who prize dynamic specimens, this gem provides a continual reminder of craftsmanship and nature working in concert.

In comparing reflective qualities to other gemstones in its category, this alexandrite stands out for a few key reasons. Alexandrite, a gem variety of chrysoberyl, typically shows an adamantine to subadamantine luster that yields strong light return and a crisp appearance, and this stone follows that pattern while offering the added intrigue of a true color change. Compared with sapphire, which usually offers a deep, vitreous brilliance with strong saturation in single colors, alexandrite adds the unique ability to present two moods in one gem, green in cool light and reddish green in warm light. Compared with emerald, which can present lush green color but often exhibits significant inclusions that soften brilliance, this alexandrite maintains lively sparkle despite its slightly included clarity grade, because chrysoberyl structure transmits light with more lively reflection. Spinel and garnet can offer intense single tone colors and pleasing brilliance, but they rarely provide the same degree of color change and the same adamantine luster that chrysoberyl variety alexandrite delivers. Even compared with other alexandrites, this Ceylon example is notable for its intense color intensity and the balance of transparency and polish, meaning that its reflective qualities favor crisp facets and defined flashes of color rather than a more muted or hazy glow.

Choosing this alexandrite from The Natural Gemstone Company is an invitation to own an heirloom that answers both the emotional need for a meaningful symbol and the practical desire for a durable, wearable gem. At 1.87 carats and with a hardness that allows for daily wear, this trillion cut stone sits beautifully in bezel, three prong, or custom modern settings that showcase the triangular form and allow light to animate the color shift.
