0.67 Ct. Alexandrite from Russia

This is a beautiful, transparent alexandrite weighing 0.67 carat, cut to a pear shape with dimensions of 6.90 x 4.33 x 3.00 millimeters, and presented by The Natural Gemstone Company. The gem shows a classic and much admired greenish to purplish color change, with the green tones visible in fluorescent lighting and the richer purplish hues appearing under incandescent lighting. It has a mixed brilliant cut that balances sparkle with color saturation, a clarity grade of slightly included evaluated at eye level which gives the stone personality without distracting from its beauty, a medium color intensity that makes the change evident in varied light sources, and an excellent polish that enhances surface brilliance. This alexandrite is natural and untreated, no enhancement, and its origin is Russia, which places it among the most historically respected sources for this rare species of chrysoberyl.

When compared to other alexandrites and color changing gemstones on the market, this piece stands out for several reasons. Russian alexandrite has a reputation for clean color separation and strong change, and while top examples can command steep premiums, this 0.67 carat pear offers a compelling balance of optical character and value. Many stones offered online are heat treated, diffused, or synthetically created to boost color, but this gem is unenhanced, preserving its natural chemistry and provenance. The mixed brilliant cut is a modern approach that keeps light return lively while preserving enough depth for color change, unlike shallow cuts that can wash out hue, or deep cuts that can mute sparkle. The slightly included clarity at eye level is typical for natural alexandrite and in many cases remains invisible once set, especially when framed with complementary stones. Relative to other market offerings in the same weight class, this alexandrite provides superior polish and a pleasing pear silhouette that reads larger than its weight suggests, making it an excellent choice for someone seeking an authentic, wearable color change gem without the extreme rarity price of larger Russian stones.

For a custom design, this alexandrite pairs wonderfully with a variety of complementary gemstones to emphasize either its greenish identity or its purplish persona. A halo of small, well matched white diamonds will amplify brightness and create a striking contrast, making the green tones pop in daylight and the purple glow sing by lamplight, especially when set in platinum or white gold. For a warmer presentation that accentuates the purple side, consider pairing with small rose gold accent beads or tiny pink sapphires, which will harmonize with incandescent tones and lend an elegant, romantic cast. For a bolder, colored frame, deep green tsavorites or teal sapphires will reinforce the green view and create a jewel like, vintage feel, while violet spinels or well matched purple sapphires will dramatize the purple face under warm light. Pearls can give a soft, classic counterpoint and are ideal for pendants where the color change becomes an intriguing secret shared with the wearer. Each of these combinations allows the alexandrite to be the focal point while creating a living interplay of hues as lighting changes throughout the day.

Design choices and setting methods influence how the color change reads and how the gem performs in everyday wear. A prong setting with minimal metal over the table keeps light flowing through the stone and maximizes the color shift, while a low bezel will protect the pavilion and edges for a more active wearer, slightly modifying how boldly the color change presents. Orienting the pear with the point down in a pendant creates a fluid drop that catches different light angles, whereas a ring design with the pear set point toward or away from the finger can alter perceived size and presence. A halo of melee diamonds or colored accent stones will both protect and highlight, making small inclusions less noticeable and creating a luminous frame that toggles between cool and warm complements. Metal choice is a powerful tool, white metals enhance the greenish cool side and give a modern aesthetic, yellow gold will warm the presentation and often deepens the purple tendency, and rose gold will feel very feminine and elevate the purple glow under lamp light. For custom work we recommend keeping side stone colors and metal tones in dialogue with the dominant color you wish to emphasize, and placing the gem so that natural light can reach the table directly to show off the most dramatic change.
