This transparent, GIA certified blue paraiba tourmaline from Brazil weighs 0.86 carat and measures 8.13 by 5.23 by 2.97 millimeters. The stone is fashioned as an oval with a mixed brilliant cut, has an intense color intensity, and carries a clarity grade of slightly included as evaluated at eye level. The finish is reported as excellent polish, and the specimen has been heat treated as an enhancement. The dimensions produce an overall depth of approximately 44.5 percent, a proportion that contributes to the balance between color saturation and light return for this particular oval profile. The Natural Gemstone Company provides the accompanying GIA documentation that confirms the origin, weight, and treatment parameters stated here.
The mixed brilliant cut is calibrated to amplify the paraiba tourmaline s inherent interaction with light by combining a brilliant facet pattern on the crown with complementary pavilion geometry, producing concentrated flashes and even color distribution. The crown facets act to fragment and scatter incoming light, creating dynamic scintillation across the oval surface, while the pavilion facets are oriented to maximize internal reflection and efficient return of light through the table, which enhances perceived brilliance. The stone s moderate depth helps the intense blue color appear vivid without becoming overly dark, and the elongated oval outline encourages longitudinal flash and motion that emphasize the copper induced blue green hue typical of Brazilian paraiba material. Slight inclusions are present at eye level, and they contribute a natural fingerprint without significantly interrupting the overall transmission of light. The excellent polish sharpens facet junctions and improves surface reflectivity, allowing light to enter and exit the gem with minimal loss, and the controlled heat treatment further optimizes the clarity and color uniformity achieved by the cutting strategy. Together, these characteristics yield a balanced presentation that highlights both the saturated color and the lively optical performance expected from a quality paraiba tourmaline.
