2.84 Ct.Tw.Total Carat Weight Cabochon Amethyst Pair from Brazil

This pair of amethysts from The Natural Gemstone Company comprises two round cabochon stones weighing 1.38 carats and 1.46 carats respectively, with dimensions of 6.99 x 6.99 x 4.24 millimeters and 6.99 x 7.01 x 4.42 millimeters. Both stones present a classic domed profile in a round outline, the diameter consistency indicating careful preforming to achieve pairability for matched jewelry applications. Origin is Brazil, which is consistent with the saturated violet to purple hue observed, and enhancement is limited to controlled heat treatment applied to stabilize and intensify color. The weight and dimension tolerances put these stones well within the typical matching standards for earrings or matched set components, with less than 0.08 carat difference and dimensional variance under 0.03 millimeters across corresponding axes, a degree of uniformity that facilitates symmetric mounting and predictable visual balance in finished pieces.

From a cutting and optical perspective these amethysts are cabochon cut, which emphasizes color and internal character over faceting brilliance, and the cutting execution shows a balanced dome curvature and even girdle proportion. The cabochon profile maximizes the absorption and scattering of light within the material, enhancing the perceived depth of the intense purple color, while the excellent polish yields a high luster surface reflective quality that reads clean under direct illumination. Clarity is graded slightly included at eye level, indicating internal features are detectable to a trained observer when viewed without magnification under normal lighting conditions, but they are not dominant or detracting from the overall visual saturation. Optical properties of quartz based amethyst, including a refractive index in the range of approximately 1.544 to 1.553 and a specific gravity near 2.65, support good light interaction in cabochon form, and the heat treatment applied here is a conventional thermal enhancement that optimizes the purple saturation without introducing filling substances or diffusion processes, preserving structural integrity and long term stability.

Practical considerations for setting and care reflect the material and cut characteristics, and these cabochons are ideally suited to bezel and closed back settings that protect the rounded profile while enhancing color depth through a dark or reflective backing. The slightly included clarity grade recommends that settings avoid pressure points on thin girdles, and mounting should allow gentle seat support across the pavilion to reduce strain. Mohs hardness of seven affords everyday wearability in rings and earrings, with typical resistance to scratches from common household compounds, yet care should be taken to avoid hard knocks or abrasive contact which can mar the polished dome. Cleaning is best accomplished with warm soapy water and a soft brush, drying with a lint free cloth, and the absence of resin or fracture filling in these heat treated stones permits safe use of ultrasonic cleaners in most cases, although mechanical vibrations should be avoided for mounted pieces until the setting is secure. For designers and retailers seeking a matched purple cabochon pair with rich color, uniformity of size, and traditional Brazilian provenance, this pair offers an excellent balance of aesthetic impact and technical soundness, and The Natural Gemstone Company stands behind the stated specifications, offering additional information on color grading, treatment documentation, and recommendations for optimal setting practices upon request.
