7.90 Ct. Ametrine from Ceylon (Sri Lanka)

This listing presents a transparent 7.90 carat oval bi color ametrine, a gem that combines both citrine yellow and amethyst purple in a single crystal, offering natural contrast and visual depth. The stone measures 14.65 by 11.61 by 7.83 mm, and its proportions are calibrated to present a generous face up size while retaining balanced depth for optical performance. The mixed brilliant cut has been executed to optimize scintillation and table brightness, and the excellent polish enhances surface reflection across the facet array. At eye level the clarity is graded very very slightly included, indicating only minor internal characteristics that do not detract from overall transparency or visual appeal. The medium color intensity of each hue provides clear separation between the yellow and purple zones without overpowering saturation, resulting in a balanced and appealing bi color effect.

Origin information is part of the gem story, and this ametrine comes from Ceylon Sri Lanka, a source noted for producing fine gemstones with stable crystal quality. The stone has undergone heat treated enhancement, a commonly accepted practice in the trade which in this case serves to refine color tone and uniformity while retaining the natural dichroic character of the material. The combination of a careful mixed brilliant cut and an excellent polish serves to maximize the gem s natural light performance, yielding strong internal reflections and lively surface lustre. The measured dimensions and substantial carat weight make this ametrine suitable for a range of settings, particularly solitaire and halo ring treatments or bespoke pendant designs where the bi color zoning can be oriented for maximum visual impact. All factual attributes and the provenance statement are provided to enable clear and informed consideration for its intended use.

Over time the intrinsic qualities of this ametrine will continue to captivate, owing to its stable crystal structure and enduring optical contrast between the two color zones. With a hardness that is consistent with secure everyday wear when set appropriately, this gem may be enjoyed for years and passed down as an heirloom, while standard care will preserve polish and brilliance. Routine cleaning using warm soapy water and a soft brush, and avoiding prolonged exposure to extreme heat or harsh chemicals, will maintain the stone s appearance and prevent unnecessary wear. When mounted in a protective setting that minimizes contact with hard surfaces, the mixed brilliant faceting will continue to present lively scintillation and the medium color intensity will retain its pleasing balance. The Natural Gemstone Company offers this ametrine as a documented example of the species, with clear specification of weight, dimensions, cut, clarity, color intensity, treatment, and origin to support long term appreciation and informed custodianship.
