5.17 Ct. Ametrine from Ceylon (Sri Lanka)

A single radiant shaped bi color ametrine weighing 5.17 carats presents itself as a study in classical elegance, a gem that bridges two storied colors with the poise of a museum piece. Measuring 12.57 x 11.38 x 5.66 mm, this stone has been given a designer cut that honors both brilliance and balance, and an excellent polish that allows light to travel freely through its fields of color. Evaluated as eye clean at eye level, and showing a light color intensity, this ametrine carries an air of antique refinement that recalls the great gemstones of history. Originating from Ceylon Sri Lanka and heat treated to enhance its natural beauty, this gem reflects the careful stewardship and ethical sourcing that collectors expect from The Natural Gemstone Company.

In hue and tone this Ceylon ametrine occupies a unique place among world famous gems, offering a softer, more ethereal interplay than the deep dichroic contrasts of the Anahi mine ametrines of Bolivia, which are renowned for their vivid, saturated purple and golden yellow zoning. Compared to Brazilian amethyst from Minas Gerais, which often presents a rich, velvety violet, this piece leans toward a lighter, more transparent lavender, paired with a pale, honeyed citrine tone that suggests sunlight filtered through antique glass. Against classic Ceylon sapphires known for their crisp cornflower blue and lively medium tones, this ametrine demonstrates a more delicate tonal subtlety, its two colors blending with gentle transitions rather than the singular, piercing saturation associated with those famed blue stones. When set beside warm Brazilian or Spanish citrines that display deep, orangey warmth, the yellow portion of this ametrine remains more restrained, offering a mellow, elegant champagne note that complements the cool mauve of its amethyst half. The result is a gem that honors tradition and legacy, suitable for timeless settings that emphasize provenance and refined taste. For collectors and connoisseurs seeking a historically resonant gemstone with refined tonal balance, The Natural Gemstone Company presents this Ceylon radiant ametrine as a lasting emblem of heritage and quiet distinction.
