7.47 Ct. Ametrine from Ceylon (Sri Lanka)

If you have been searching for a single stone that answers both the heart and the eye, this exquisite transparent 7.47 carat oval bi color ametrine may be the answer you have been waiting for. Carefully cut to an elegant oval shape with measurements of 14.91 by 11.69 by 7.22 millimeters, this gem combines the warm golden honey of citrine with the soft violet of amethyst in a single crystal. The mixed brilliant cut was chosen to maximize scintillation and to showcase the natural color zoning without sacrificing face up brilliance. Evaluated at eye level as eye clean, the gem offers exceptional clarity for its size, and the excellent polish ensures each facet returns light with clean, lively flashes. Enhanced by a stable heat treatment and sourced from Ceylon, Sri Lanka, this ametrine arrives as a dependable and striking option for collectors and for those planning a meaningful piece of jewelry.

When you see this ametrine in hand, what stands out first is the seamless conversation between color and light. The mixed brilliant layout balances larger facets on the crown with precision pavillion facets, creating a play of light that emphasizes both color contrast and scintillation. The medium color intensity has been preserved so that neither the yellow nor the violet overwhelms the other, allowing each hue to appear distinct yet harmonious as the stone moves. Because the stone is eye clean, light passes through without obstruction, giving the colors a luminous, glasslike quality that is especially compelling when mounted in open settings where light can penetrate from multiple angles. In photographs and in person the gem reads as both delicate and bold, making it an ideal centerpiece for an engagement ring that will feel unique and personal, or a collector piece that demonstrates the best qualities of ametrine.

Comparing reflective qualities to other gemstones in its category helps explain why collectors and connoisseurs are drawn to fine ametrine. As a quartz variety, ametrine has a refractive index that produces a softer brilliance than higher index gems such as topaz or sapphire, and it shows less fire than gemstones with higher dispersion values. Where amethyst and citrine separately offer strong color and reasonable brilliance, ametrine’s real advantage is the internal juxtaposition of two complementary colors within a single crystal. This color zoning creates a dynamic internal contrast that can appear as flashes of warm gold against cool violet as the stone moves, a visual effect that many find more captivating than simple high dispersion sparkle. Compared to tourmaline, which often displays stronger pleochroism and deeper saturated tones, this ametrine offers a lighter, more pastel palette and a more transparent window to the interplay of hues. Against topaz, ametrine will show subtler fire, but the mixed brilliant cut and superb polish of this example compensate by producing lively facet contrast and crisp reflections that emphasize color transitions rather than spectral fire. In short, if you seek a stone whose reflective character is defined by color play and refinement rather than by overt brilliance or fire, this ametrine stands apart.

For customers looking for the ideal engagement ring stone or a rare addition to a curated collection, this ametrine answers several practical needs as well as aesthetic desires. With a Mohs hardness of about 7, quartz is durable enough for many types of jewelry when set thoughtfully and cared for properly, and the generous size of 7.47 carats gives ample presence to serve as a signature piece. The eye clean clarity and excellent polish mean fewer worries about hidden inclusions or dull facet junctions, and the medium color intensity provides a versatile look that complements both warm and cool metals. The heat treatment noted is a common and stable enhancement that improves color consistency and is disclosed for full transparency, a commitment to integrity that you can expect from The Natural Gemstone Company. Origin Ceylon, Sri Lanka imparts a provenance that many collectors favor for the quality of its stones, and the measured dimensions make this gem suitable for classic solitaire settings, halo designs that amplify contrast, and bespoke creations where the cutter and setter work together to orient the color zones to best effect.
