5.37 Ct. Ametrine from Ceylon (Sri Lanka)

This pear shape bi color ametrine of 5.37 carats is an exceptional specimen, and it stands out in both size and color when compared to typical ametrine offerings. Measuring 13.84 by 9.83 by 7.58 millimeters, this stone occupies a realm of scale that is uncommon for bi color ametrines, most of which are smaller and display less dramatic color separation. The intense color intensity in this gem produces a vivid and saturated display of golden citrine tones graduating into deep amethyst purple, creating a striking visual contrast that is particularly rare in larger stones. The mixed brilliant cut has been executed to balance fire and color zoning, producing an impressive return of light while preserving the natural bi color character, and the excellent polish gives a crisp, mirror like finish that enhances both brilliance and transparency.

From a gemological standpoint this ametrine offers attributes that matter to the educated buyer, and The Natural Gemstone Company is pleased to present this stone with full disclosure. Clarity is graded as very very slightly included, evaluated at eye level, which means the inclusions are minimal and do not interfere with the gem s appearance or its optical performance under normal viewing conditions. The combination of near clean clarity, intense color, and substantial carat weight makes this an inherently rare and desirable material. The piece has been heat treated, a stable and widely accepted enhancement that intensifies the natural hues and improves uniformity without compromising structural integrity, a fact that responsible buyers appreciate for long term value. Origin is Ceylon Sri Lanka, a region internationally recognized for producing high quality gemstones, and provenance from this locality adds cultural and market credibility for collectors and connoisseurs.

For investors and collectors who value scarcity, this ametrine is compelling because large bi color stones with this level of saturation and clarity are uncommon in the market. The cut and polish maximize wearable beauty while retaining the natural zoning that defines ametrine s appeal, and the documented heat treatment and Sri Lankan origin provide transparent information for appraisal and resale. Presented by The Natural Gemstone Company, this gem is suitable for a high quality custom setting or as a centerpiece in a serious collection, offering both immediate visual impact and long term desirability.
