6.38 Ct. Bi Color Ametrine from Brazil

Ametrine has long carried the aura of myth and the weight of centuries, a stone whose very name whispers of duality, balance, and the marriage of two of the earths most beloved colors, violet and golden yellow. This particular example offered by The Natural Gemstone Company is a beautiful transparent 6.38 carat oval bi color ametrine whose form and finish speak to both nature and the hands of the cutter, a mixed brilliant faceted style that brings out clarity and sparkle. At 13.15 by 10.42 by 8.37 millimeters the gem is substantial enough to command the center of a ring or pendants, yet its proportions remain classic and timeless. Historically ametrine is celebrated for its Bolivian Anahi mine provenance, where dramatic purple and yellow zoning became famous, while the traditions of gem cutters from older European workshops often favored cuts that preserve the clear division of color. This Brazilian origin specimen follows that same lineage of reverence for the natural dichroism, while offering a unique tonal personality of its own, warmer in the yellow, and richer in the amber transitions than the sharply contrasted Bolivian material.

Technically the gem is notable for its intense color intensity, and for a clarity grade described as very very slightly included when evaluated at eye level, a combination that gives it both presence and purity. The mixed brilliant cut works in harmony with the bi color character, creating scintillation in the golden zones and a velvety depth in the violet flashes. The excellent polish reveals the internal landscape with exceptional transparency, and the heat treatment enhancement has been applied to stabilize and intensify the hue, a common and accepted practice that maximizes the gemstones visual potential while retaining natural integrity. When comparing its hue and tone to gemstones from other famous locations, one can see that the golden field leans toward the warm citrus and honey notes often seen in Brazilian citrine, yet the violet areas carry a cooler, noble purple akin to high quality amethyst from Uruguay, though without the deep bluish saturation of some Zambian amethysts. This balance gives the stone a more classical and wearable warmth than some of the more saturated foreign specimens, and yet it preserves the regal purple that evokes centuries of royal jewelry.

To place this gem in the broader history of fine stones, consider how jewelers in the past have prized pieces that can tell a story through color alone, stones that bridge the light between the warm and the cool, the sunlit and the shadowed. The oval shape and mixed brilliant faceting of this piece align with design language from both Victorian and Art Deco eras, where emphasis on proportion and light was paramount. In use the tones of this ametrine will pair beautifully with warm yellow gold for a historically resonant appearance, or with soft platinum tones for a more modern, restrained contrast. When comparing its hue and tone to gemstones from other famous locations, the ametrine shows a unique temperament, not the sharp dichroic split of Anahi Bolivian stones, nor the singular deep purple of classic Uruguayan amethysts, but a sophisticated middle ground. This middle ground offers collectors and connoisseurs a gem that reads as antique elegance, yet is fresh enough to carry contemporary design.

Owning this piece through The Natural Gemstone Company means adding to a collection not only a well cut and well finished gem, but also a link to generations of gem lore and craftsmanship. A 6.38 carat oval bi color ametrine of this quality is rare enough to be an heirloom, and its Brazilian origin brings its own narrative of New World deposits and the modern lapidary traditions that have refined raw beauty into wearable art. We disclose the heat treatment openly, as transparency has long been a cornerstone of lasting relationships between dealer and client, and the stones very very slightly included clarity assures you of both natural origin and enduring beauty. For a bespoke commission, settings that honor the historical resonance of the piece will preserve its legacy, while modern minimal settings will show off the intense color intensity and excellent polish for daily admiration.
