Product description

As a gemstone specialist at The Natural Gemstone Company I am proud to present a truly timeless treasure, a transparent pear shaped bi color ametrine weighing 7.75 carats with dimensions of 12.71 x 13.37 x 8.50 mm. This gem is faceted in a mixed brilliant cut that balances scintillation and depth, revealing a dramatic and natural division between rich amethyst purple and warm citrine gold, a color contrast that has captivated wearers since ametrine first reached Europe through ancient trade routes. The clarity is very very slightly included when evaluated at eye level, allowing brilliant light return and clean color zoning, and the intense color intensity and excellent polish give it a classical presence ready for heirloom settings. Originating from Brazil and enhanced by careful heat treatment to stabilize and refine its hues, this ametrine embodies the romance of Old World gems while meeting modern standards of lapidary excellence, making it ideal for collectors who appreciate history and legacy in a wearable form.

When considering durability, ametrine is a variety of quartz and rates 7 on the Mohs hardness scale, which places it well above common jewelry materials and ensures strong resistance to everyday scratches. For perspective, diamond rates 10, ruby and sapphire rate 9, topaz rates 8, and quartz varieties like ametrine rate 7, meaning this gem is durable enough for frequent wear, provided it is protected from hard knocks and abrasive surfaces. For rings and settings that will see daily use, I recommend a secure bezel or protective halo to preserve the stone edges and the faceted mixed brilliant pavilion, and routine gentle cleaning with mild soap and warm water is ideal to maintain its polish and intense bi color display. At The Natural Gemstone Company we can advise on settings and sizing to suit the pear shape and to ensure the gem retains its classical beauty for generations, a living connection to the rich history of colored gemstones. If you seek a piece that links tradition with wearable sophistication, this Brazilian ametrine is an exceptional choice, and I am happy to help guide you through mounting options, certification, and care.
