5.25 Ct. Bi Color Ametrine from Brazil

Presenting a beautiful transparent 5.25 carat oval bi color ametrine measuring 12.27 x 9.36 x 7.92 mm, this gem is faceted with a mixed brilliant cut that balances fire and color zoning for maximum visual impact. The clarity has been evaluated at eye level as very very slightly included, meaning inclusions are minimal and not visible to the naked eye, which enhances both appearance and value for collectors and wearable pieces. Color intensity is described as intense, with a vivid transition between golden citrine tones and purple amethyst tones that is characteristic of fine ametrine, and the excellent polish and precise faceting deliver strong light return and scintillation. Origin is Brazil, a known and reputable source for gem quality ametrine, and the stone has undergone a standard heat treatment to stabilize and intensify the color, an accepted enhancement within the trade that should be disclosed to buyers. The oval shape and dimensions make this piece ideal for a classic solitaire ring or a bespoke pendant, and the mixed brilliant cut preserves weight while optimizing brilliance.

As an investment grade specimen, this 5.25 carat bi color ametrine presents compelling potential for future appreciation, due to the combination of its size, clean eye level clarity, intense natural looking color, and uncommon bicolor zoning. Larger ametrines with attractive color separation are relatively scarce in the market, and educated buyers increasingly seek distinctive colored gemstones as a portfolio diversification against traditional assets. The fact that this gem is well cut, well polished, and comes from a reputable Brazilian origin increases its marketability and liquidity, while the disclosed heat treatment is stable and widely accepted, posing no significant detriment to long term value. For collectors and investors who prioritize provenance and gemological integrity, retaining certificates, photographic documentation, and expert appraisals will support resale value.
