13.47 Ct. Bi Color Ametrine from Bolivia

There are stones that catch light, and then there is this whisper of sunrise and twilight captured in a single breath, a transparent bi color ametrine that seems to hold day and dusk within its facets. We present a magnificent 13.47 carat emerald cut ametrine, measured at 17.17 x 11.52 x 9.30 mm, a jewel whose linear grace is both architectural and tender, like a miniature window looking out over a landscape of lavender and warm honey. The step cut of the emerald silhouette allows the colors to settle into parallel ribbons, each facet a terrace where light rests and then releases, revealing a soft interplay of violet and champagne that feels like a secret shared between two hearts. This gem is polished to an excellent finish, its transparency unmarred, its presence luminous and deliberate, suited for an intimate setting that honors its rare, dual nature.

Under the loupe and to the eye, the clarity speaks of quality and restraint. Graded as very very slightly included, evaluated at eye level, the stone retains a clear, open gaze that allows the bi color zoning to sing without interruption. The medium color intensity strikes a balance between subtlety and statement, offering hues that are palpable without overwhelming the senses, colors that lean into romance rather than spectacle. The emerald cut emphasizes depth over flash, showing broad, elegant planes where the violet deepens near one end and a golden warmth gathers at the other, creating a gentle gradient that seems to move as you shift the gem. The excellent polish enhances every plane and corner, allowing each reflection to be clean and noble, a mirror for memory and promise.

Mined in Bolivia, this ametrine carries the quiet poetry of highland soils and ancient geology, a stone shaped by elemental patience. The material has been heat treated, a common and stable enhancement that deepens and stabilizes color, allowing the gem to express its dual personality with clarity and vigor. The result is a stone that feels both naturally born and carefully refined, a collaboration between earth and artisan. Offered by The Natural Gemstone Company, this ametrine is presented with care and provenance in mind, an object meant to become an intimate companion in the making of stories. Imagine it set in a simple gold bezel to cradle its edges, or embraced by a delicate halo that catches and returns light like laughter, each design choice a way to honor the gem's voice.

When you choose such a treasure, durability matters as tenderly as beauty. Ametrine is a variety of quartz and sits at 7 on the Mohs scale of hardness, which means it is resilient enough for regular wear, but it is not impervious. For perspective, diamond scores 10 on the Mohs scale, corundum which includes sapphire and ruby is 9, and topaz around 8, so an ametrine at 7 offers good everyday stability while remaining softer than those higher hardness stones. This implies that with mindful settings and simple care, your ametrine can be worn and loved for generations, however it is more susceptible to scratching than corundum or diamond. To ensure longevity consider protective settings such as bezels or settings that shield the girdle, avoid rough contact during heavy manual activity, and clean with mild soap and a soft brush rather than harsh chemicals or ultrasonic cleaners if inclusions are ever a concern, heat treated gems generally remain stable but gentle care will preserve the vivid two tone expression.

There is a romance in owning a stone that contains two dawns, a jewel that invites a story with each turn and each held glance. This 13.47 carat emerald cut bi color ametrine is more than a gem, it is a moment suspended, ready to be set into an engagement ring, a pendant, or a bespoke keepsake that will mark a beginning or remember a vow. The proportions of 17.17 x 11.52 x 9.30 mm give it presence without overpowering, a balanced weight for show and comfort, and its very very slightly included clarity gives character while preserving its brilliant transparency. At The Natural Gemstone Company we cherish the intimacy of such choices, and we invite you to imagine this ametrine as the centerpiece of your next expression of love, a stone that holds two colors and a thousand whispered promises.
