10.05 Ct. Ametrine from Madagascar

This exceptional transparent 10.05 carat fancy shape bi color ametrine measures 19.90 x 10.45 x 7.25 mm, and immediately sets itself apart from the common amethyst or citrine on the market. Whereas many bi color stones are small or weakly zoned, this specimen displays a medium intense color intensity with a clean, dramatic division between purple and golden tones that the step cut emphasizes with crystalline clarity. The step cut enhances the stone’s natural color zoning, producing broad, elegant planes that showcase the ametrine’s two tones more like a work of art than a mere gemstone. Clarity evaluated at eye level is very very slightly included, which is rarer and more desirable than the heavily included examples frequently offered by mass merchants, and the excellent polish gives each facet a mirror finish that maximizes light return. Compared to similar weight stones from other sources, the Madagascar origin lends this piece an extra layer of appeal, as Madagascan ametrine often exhibits cleaner zoning and more saturated color than many commercial parcels. The heat treatment enhancement used here is standard, stable, and professionally executed to accentuate color without compromising transparency, giving you a gem that is both beautiful and dependable in daily wear.

As a piece destined to become a generational heirloom, this ametrine offers tangible advantages over competing options, including larger size, distinctive bi color character, and a classical step cut that will remain stylish across changing trends. A stone of this weight and clarity encourages a jeweler to design a substantial, protective setting in platinum or 18 karat gold, such as a low profile bezel or secure multi prong mount, which preserves the gem and allows its color zoning to be admired from multiple angles. Unlike fragile or heavily included stones that require frequent repairs, this ametrine’s combination of transparency and excellent polish means minimal maintenance, making it practical to pass from generation to generation. When purchased from The Natural Gemstone Company you also gain provenance and expert guidance on care and resale considerations, documentation that strengthens the gem’s narrative and market value over time. With proper setting, routine cleaning, and the careful stewardship of your family, this bi color ametrine will not only be a striking fashion statement today, but a storied centerpiece to inherit and treasure tomorrow.
