This refined and highly aesthetic specimen from the Equiter Mine in Rio Grande do Norte, Brazil showcases the classic signature of this coveted locality: a prominent bright blue line running along the c-axis of the primary euclase crystal. Measuring 26.8mm x 18.25mm x 16.5mm, the piece is anchored by a beautifully double-terminated main crystal, which proudly protrudes above the contrasting white feldspar matrix, creating a dramatic and elegant display.

The central euclase is sharp, glassy, and well-formed, accentuated by a scattering of a few smaller companion crystals that add depth and complexity to the arrangement. The brilliant internal blue line, a hallmark of Equiter material, lights up the otherwise water-clear crystal with a vivid internal fire that is instantly recognizable and highly prized by collectors.

Despite its modest overall size, this specimen embodies the proportions, balance, and presentation of a world-class fine mineral specimen. The combination of crystallographic perfection, optical color zoning, and natural isolation on matrix makes it an exceptional and desirable piece—a textbook example of why Brazilian euclase is so celebrated on the world stage.
