1.00 Ct. Beryl from Brazil

This transparent 1.00 carat emerald cut bluish green beryl measures 6.46 by 5.45 by 3.90 millimeters, and displays a medium color intensity with a clear bluish green hue. The stone has a clarity grade of very slightly included, evaluated at eye level, and an excellent polish that enhances transparency and surface luster. The cutting style, an emerald cut, emphasizes clean step facets that retain weight while presenting the color and internal structure in balanced planes. There has been no enhancement to alter color or clarity, and the specimen is of Brazilian origin. This gemstone is offered by The Natural Gemstone Company with full disclosure of its natural characteristics.

The story of this beryl begins millions of years ago deep within the continental crust, where granitic magmas intruded and evolved into coarse grained pegmatites. As the pegmatite bodies cooled slowly, hydrothermal fluids rich in beryllium, aluminum, silica, and trace iron circulated through fractures and pockets. Under persistent heat and pressure, and with abundant space in late stage pegmatitic cavities, beryl began to nucleate and grow in well formed prismatic crystals. The presence of iron in the crystal lattice influenced the absorption of light and produced the bluish green tone characteristic of this specimen, rather than the intense green associated with chromium or vanadium. Over prolonged geological time, fluctuating temperatures and fluid chemistry produced minute entrapped inclusions and growth zones, accounting for the very slightly included clarity noted at eye level. Subsequent uplift and erosion liberated the pegmatite fragments, allowing the crystals to be recovered from alluvial and primary deposits in Brazil. Carefully faceted to an emerald cut, this 1.00 carat beryl preserves natural transparency and medium color intensity, and the excellent polish was executed to reveal optical depth and to minimize surface distortion. The combination of its natural provenance, absence of enhancement, measured dimensions, and assessed clarity present a precise record of its geological origin and subsequent lapidary refinement.
