6.18 Ct. Ametrine from Brazil

A rare and arresting example of nature and masterful cutting, this one transparent 6.18 carat pear shape bi color ametrine is a singular offering from The Natural Gemstone Company, an invitation to own a gem that will reside in a very exclusive collection. Measuring 15.15 by 10.99 by 7.78 mm, the stone is rendered in a mixed brilliant cut that maximizes scintillation while preserving the dramatic bi color character that makes ametrine so coveted. Evaluated as eye clean at normal viewing distance, with a medium light color intensity and an excellent polish, this gem presents a clarity and finish usually reserved for bespoke commissions. The piece has been heat treated to enhance its intrinsic color balance, and its origin in Brazil speaks to the finest known sources for collectible ametrine. Because each ametrine carries its own unique zoning and color interplay, owning this particular pear means owning a one of a kind tableau of violet and warm golden tones that will respond to light with a personality all its own.

Viewed from the table, the pear silhouette draws the eye into a luminous heart, as the mixed brilliant facets throw controlled flashes that reveal the gem's dual temperament. One end leans toward a soft amethyst lavender, the other toward a champagne to golden citrine warmth, the split flowing across the stone in an organic and painterly way. The medium light intensity keeps the colors fresh and wearable, allowing the shifting hues to be visible in both daylight and evening light, while the eye clean clarity ensures those flashes are uninterrupted by obvious inclusions. The excellent polish gives each facet crisp edges and mirror like surfaces, so that the stone will communicate with every movement. The heat treatment performed is a common and accepted enhancement for ametrine, employed to stabilize and refine the natural color zoning without diminishing the gem's natural character, and because this specimen comes from Brazil, collectors will recognize the classic and desirable palette it exhibits.

For a custom piece that honors the gem while elevating its rarity, imagine this pear set as a solitaire on a tapered cathedral in 18 karat rose gold, the warm metal echoing the citrine tones while the rose hue flatters the lavender face, creating an intimate and feminine statement ring that feels both modern and timeless. For a more dramatic couture approach, picture a delicate halo of bead set colorless diamonds hugging the pear, with three graduated trillion cut pale citrines set on the shoulders to reinforce the golden edge, the contrast creating depth and a jewel like tapestry of light. Alternatively, a bespoke necklace would allow the stone to dangle freely, paired with subtle accent stones such as minty green tourmaline drops or petite tsavorite garnets spaced along a fine chain to introduce an unexpected fresh green counterpoint, the green serving to amplify the violet while harmonizing with the warm zones. If you prefer a cool palette, a platinum bezel with a micro pave of white diamonds and two baguette cut light violet sapphires at the base will emphasize the amethyst side, producing a refined, cool toned composition that reads contemporary and rare.
