6.60 Ct. Ametrine from Brazil

This exceptional bi color ametrine from Brazil is presented as a transparent, emerald cut gemstone weighing 6.60 carats, with dimensions 13.71 x 9.70 x 6.31 mm. The emerald cut is an ideal choice for a stone with strong bicolor zoning, because its long, rectangular facets and broad table emphasize the distinct purple and golden yellow hues that define ametrine. The gem displays intense color intensity, with an elegant balance between the amethyst purple and the citrine golden tones. The cut and proportions create clean step facets that produce a calm, sophisticated flash, and the excellent polish enhances surface luster and the crispness of the color separation. This level of polish and cutting precision is particularly important in larger stones, where any surface irregularity can become obvious, and it ensures that the gem reads beautifully in a variety of settings and lighting conditions.

Clarity and transparency are fundamental attributes that determine both the aesthetic presence and the practical value of a gemstone, and this ametrine is graded as very very slightly included, evaluated at eye level. In practical terms this means that under normal viewing conditions the stone appears clean, with only minimal internal characteristics that do not detract from the visual impact or structural integrity. The transparency and low inclusion profile allow light to travel through the stone with minimal obstruction, which maximizes color saturation and visual depth. Heat treatment has been applied, which is a common and accepted enhancement for ametrine to stabilize and intensify color zoning, and this treatment is disclosed to maintain full transparency for buyers. The origin of this piece is Brazil, a renowned source for high quality natural ametrine, and the geographic provenance contributes to the gemological identity and market desirability of the stone.

For an engaged buyer who values both uniqueness and enduring wearability, this bi color ametrine represents a compelling alternative to traditional engagement stones. As a variety of quartz, ametrine generally has a hardness of about seven on the Mohs scale, which offers reasonable durability for everyday wear, while also being more forgiving and affordable than many precious stones. The emerald cut presentation is especially suitable for an engagement ring, because the geometric form complements classic and modern settings alike, and the broad table showcases the bi color nature in a way that invites conversation and admiration. Practical setting choices can enhance longevity and visual appeal, for example four prong settings that protect the corners, bezel treatments for added security, or a custom design that uses accent stones to either frame the bicolor division or to provide contrast. For an educated buyer, the combination of size, transparency, intense color, and precision cutting makes this ametrine a memorable, wearable center stone that stands apart for both aesthetic and symbolic reasons.

At The Natural Gemstone Company we emphasize full disclosure, consistent grading language, and sourcing transparency, and this ametrine is offered with those values in mind. We describe the gem as heat treated, originating from Brazil, and assessed as very very slightly included at eye level, with an excellent polish and intense color intensity. For buyers considering an engagement purchase, we recommend an appraisal and a discussion about desired settings, metal choices, and protective design elements, so that the final piece reflects both the statement you wish to make and the practical requirements of daily wear. Our gemologists are available to provide additional optical imagery, facet analysis, or custom design consultation, to ensure that this striking bi color ametrine becomes an enduring symbol of commitment and personal style.
