14.19 Ct. Ametrine from Bolivia

There are few gemstones whose very existence reads like a page from antiquity, and yet speaks with a fresh voice to the modern collector, and this Bolivian ametrine is one such treasure. Ametrine has been celebrated since the discovery of the famed deposits of Bolivia, where nature conspired to produce a single crystal that carries both the regal violet of amethyst and the warm gold of citrine. At The Natural Gemstone Company we present this 14.19 carat cushion shaped bi color ametrine as an heirloom quality stone, born of geological time and human admiration. Its size alone places it among the rarest examples one will encounter on the market, because most ametrines of fine color are found in considerably smaller dimensions. To hold a stone measuring 15.03 x 14.91 x 10.94 mm is to hold a compact history of the earth, a visible record of heat and pressure and mineral chemistry shaped into a form that has captured the fancy of jewelers and connoisseurs for generations. The checkerboard cut that crowns the table is a modern nod to classic lapidary art, a faceting approach that invites light to travel across the dividing line of color, creating a subtle dance of violet and golden tones that feels as timeless as it is rare.

From a gemological perspective this specimen is exceptional in both proportion and purity, qualities that are especially uncommon in bi color stones of this scale. At 14.19 carats the ametrine exceeds the carat weight of most competitive stones, while its medium intense color intensity provides a balanced saturation that reads as vivid without overwhelming the eye. The bi color zoning is distinctly visible and crisply presented across its cushion plane, showing a harmonious transition rather than a muddled blend, a trait that collectors prize when evaluating rarity. The checkerboard cut amplifies this rare color interplay by producing a tapestry of small, reflective facets that break and rejoin the color fields with every tilt of the gem. Clarity is rated eye clean when evaluated at eye level, which means that the gem offers an unobstructed visual experience to the naked eye, free from inclusions that might distract from its dual coloration. The excellent polish completed by our master cutters further ensures that each facet edge is crisp and reflective, maximizing brilliance and satiny luster. Enhancement has been performed by heat treatment, a common and stable practice that refines color while preserving the natural origin and structural integrity of the crystal. Origin is Bolivia, the historic and principal source of genuine ametrine, a provenance that adds both narrative and value to the piece.

Collectors and designers who value tradition will recognize in this ametrine the attributes that make a gem worthy of legacy status, attributes that are increasingly scarce in today s market. Because large, well colored, eye clean ametrines are seldom encountered, every opportunity to acquire such a stone is significant for those building a collection intended to endure. This example lends itself to settings that honor its classic silhouette and bi color personality, whether as a solitary center stone in a three stone ring that plays with light and shadow, as a statement pendant that turns with the wearer to reveal alternating color moods, or as the focal point in an heirloom brooch that will carry stories across generations. Our team at The Natural Gemstone Company treats each stone as both a scientific specimen and an artistic medium, and we are pleased to offer bespoke mounting consultations to ensure the metal, cut orientation, and design support the gem s natural dialogue between violet and gold. For the buyer who seeks rarity in size and color, coupled with a provenance rooted in the storied mines of Bolivia, this 14.19 carat cushion ametrine represents a singular opportunity to own a gemstone that is at once ancient in origin and timeless in its appeal.
