Product description

Before you is a single extraordinary gemstone, a transparent, natural Russian alexandrite weighing 10.09 carat, with elegant cushion proportions of 13.53 x 10.88 x 7.73 mm, cut in a mixed brilliant style to marry scintillation and depth. This gem displays the legendary alexandrite color change, shifting from a bluish green in cool or fluorescent light, to a rich reddish purple in warmer illumination, a phenomenon that has captivated collectors for more than a century. Its intense color intensity is complemented by a clarity that is eye clean when examined at eye level, allowing the color change to read with purity and drama without distraction. The excellent polish maximizes light return and the mixed brilliant faceting pattern brings alive both the stone of its present moment and the mystery of its moods as light alters its face. Importantly this gem is entirely natural, with no enhancement, a quality that elevates its desirability and its suitability as a legacy piece. The Natural Gemstone Company is proud to present such an austere and rare alexandrite, a piece that will serve as a signature acquisition for a discerning connoisseur.

Possessing this alexandrite is to own a story that began deep within Russian deposits renowned for producing some of the finest examples of the species, and to join an exclusive circle of collectors who value provenance as much as perfection. Russian alexandrite of this size and purity is exceptionally scarce, and a 10.09 carat stone that is eye clean and untreated is rarer still. At The Natural Gemstone Company we approach each sale not as a transaction, but as an invitation to bespoke ownership, offering curated suggestions for settings that will protect this gem while showcasing its dramatic color tunability. Consider a classic, low bezel for everyday protection, or a bespoke palladium or platinum ring with hand engraved shoulders to frame the cushion shape without competing with its chromatic display. For those who favor a more modern aesthetic, a minimal prong setting with a custom gallery will allow light to flood the pavilion to accentuate the transition from bluish green to reddish purple, ensuring the stone performs at every opportunity.

A gemstone of this stature is an ideal candidate to become a generational heirloom, a centerpiece that will be cherished and entrusted across decades. Alexandrite belongs to the chrysoberyl family, celebrated for durability and resistance to wear, attributes that make it suitable for frequent wear when set thoughtfully, thereby allowing it to accompany celebrations and daily life alike. Because this stone has not been subjected to any enhancements, its natural state preserves both beauty and integrity, ensuring that future generations receive the gem exactly as nature created it. Passing this alexandrite to heirs becomes an event, complete with provenance, a detailed record of origin from Russia, and the recommendation from The Natural Gemstone Company for independent gemological documentation and appraisal, an important step to formalize its role as a documented family treasure. A well chosen setting, periodic professional inspections, and discreet cleaning with gentle, non abrasive care will maintain the excellent polish and keep the color change vivid for children and grandchildren to discover.

Owning this 10.09 carat Russian alexandrite is to claim a place within a small and select community of custodians who prize rarity and authenticity, a choice that resonates beyond fashion into legacy. The Natural Gemstone Company offers personalized assistance to design the setting, coordinate certification, and prepare a complementary appraisal and secure shipping, creating a seamless path from acquisition to presentation as an heirloom. Opportunities to acquire such unenhanced, intensely colored, eye clean alexandrite in this weight and cut are infrequent, and when pieces of this caliber enter the market they are rapidly absorbed by collectors and families intent on preserving their exceptional character. If you seek a singular jewel that will be recognized and loved for generations, this alexandrite stands ready to begin a lineage, to be worn with confidence, and to be passed forward as a luminous emblem of taste, history, and enduring value. Contact The Natural Gemstone Company to begin a confidential conversation about commissioning the perfect setting and securing this rare gem for your family.
