At first glance, its presence is quiet and restrained, but under light it awakens with a richness that feels almost liquid. The body of the crystal carries a spectrum of warm, resinous tones that shift between deep cola like browns and glowing amber hues, as if light were slowly fermenting inside the stone rather than simply passing through it. The internal structure is far from uniform. Subtle zoning unfolds across the crystal in layered transitions, where darker smoky depths give way to clearer, honeyed windows. When illuminated directly, these internal passages ignite, releasing golden flashes and ember like reflections that lend the stone an almost organic vitality. The effect is reminiscent of aged amber suspended in time, yet unmistakably tourmaline in its optical behaviour and crystalline response. Its form is compact but sculptural, shaped by natural growth and later refinement that has softened its outer surfaces without erasing the crystal’s internal story. The silhouette feels irregular yet deliberate, offering changing perspectives as the stone is rotated. Each angle reveals a new balance between translucency and density, between shadow and glow. This is a crystal defined not by brightness alone, but by atmosphere. Its character lies in nuance, in the way colour pools and recedes, in the way light lingers rather than flashes. A Coca Cola tourmaline in spirit and tone, expressive, uncommon, and quietly captivating.

Its warm cola and amber tonality, combined with visible internal zoning, sets it apart from more typical chromatic varieties. Brazilian origin further reinforces its desirability, especially for collectors seeking distinctive specimens that prioritise depth and individuality over brightness alone. Lapidary Potential: From a lapidary perspective, the stone presents interesting possibilities due to its layered internal zoning and concentrated colour pockets. Any cutting would need to respect the natural distribution of tone to preserve its internal glow. At the same time, the crystal’s visual identity and character argue strongly for preservation in its current form, where its full optical narrative can be appreciated without reduction. —————— Shipping and Handling: All orders are shipped by UPS express or National Express. • Dispatch time: within 1 to 2 business days after payment confirmation to catawiki • Transit time with Express service: up to 3 business days within europe and worldwide • A tracking number is always provided Photography and transparency: All photos were taken under controlled light conditions, carefully selected to reproduce the most accurate natural colour of each specimen.
