10.17 Ct. Ametrine from Brazil

From the moment light finds its way into this remarkable specimen, the eye is drawn to a story that reaches back through centuries of gem lore, a story of contrast and harmony, of endings and beginnings. This one of a kind transparent bi color ametrine carries the quiet authority of the quartz family while expressing a unique personality all its own. We present a radiant shape stone weighing 10.17 carats, measuring 15.94 x 11.89 x 7.80 mm, cut in a precise radiant style that bridges classical proportions and modern brilliance. Originating from Brazil, and offered with the careful curation that defines The Natural Gemstone Company, this ametrine embodies a timeless aesthetic that will resonate with collectors and connoisseurs who favor enduring beauty over passing trends. The very very slightly included clarity, evaluated at eye level, allows the gem to remain transparent and luminous, while the excellent polish ensures every facet interacts with light in a pleasurable and refined way.

The color in this ametrine is its anthem of presence, a bold duality that reads as a single statement of personal power and distinction. One half carries a warm, golden citrine tone, the other a deep, royal amethyst hue, and the boundary between them holds a soft and purposeful dialogue rather than a harsh divide. The medium intense color intensity gives the stone undeniable saturation without overpowering elegance, preserving both depth and subtlety. The radiant cut enhances the bi color phenomenon by balancing light return and color governance, so that the purple and golden hues appear to shift and settle in response to movement and viewing angle. Worn as the center of a ring or a pendant, the color contrast becomes a language, a visual metaphor for dual strength, and a declaration that the wearer values a legacy of character over mere fashion.

Beyond its surface beauty, this ametrine speaks to a lineage of lapidary tradition that values proportion, polish, and the human hand that brings a rough crystal to its luminous potential. Heat treatment has been applied to stabilize and accentuate the gem's tones, a common and accepted enhancement that preserves the integrity of color while allowing the stone to reach an ideal state for fine jewelry. The excellent polish and the considered radiant faceting reflect a lapidary intent to honor the stone's natural zoning while maximizing brilliance and face up appeal. At 10.17 carats this is a substantial gem, a scale that invites a classic and enduring setting, a bezel with clean lines or a four prong mount that showcases the rectangular form. The dimensions of 15.94 x 11.89 x 7.80 mm make this piece versatile enough to command attention as a solitaire, and restrained enough to sit comfortably as part of an heirloom composition.

The Natural Gemstone Company sources pieces with an eye toward provenance and character, and this Brazilian ametrine is selected for its balance of hue, weight, and workmanship, all documented in its description.
