3.14 Ct. Aquamarine from Mozambique

This 3.14 carat transparent aquamarine from Mozambique presents a textbook emerald cut, precisely faceted to emphasize clean step planes and a broad table face up. The cutting style employs parallel rectangular crown and pavilion facets, producing the classic step cut flashes that reveal color in broad, even zones rather than dispersed brilliance. The stone measures 11.46 millimeters by 7.04 millimeters by 5.20 millimeters, yielding an overall depth of approximately 45.4 percent, a proportion that balances spread with sufficient pavilion depth to concentrate color. The clarity grade is very slightly included evaluated at eye level, and the inclusions are minor, localized to lower pavilion planes and not disruptive to loupe free viewing, which is ideal for a step cut that prioritizes clarity. The color intensity is described as light, presenting a clean, cool blue with subtle green undertones, and the piece exhibits an excellent polish with crisp facet junctions and smooth girdle finishing. Enhancement is heat treated, a standard and stable practice for aquamarine which reduces yellow tones and refines the blue, and the origin Mozambique is noted for producing aquamarines with attractive blue saturation and good clarity characteristics. The Natural Gemstone Company presents this gem as a finely executed example of emerald cut beryl work, suitable for collectors and high end jewelry use.

On the Mohs hardness scale aquamarine, as a variety of beryl, registers at approximately 7.5 to 8, which translates to very good resistance to scratching for everyday wear while requiring more care than corundum and diamond. For context diamond is 10 Mohs, corundum such as sapphire and ruby is 9 Mohs, topaz is 8 Mohs, and quartz is 7 Mohs. This means the aquamarine will tolerate standard wear well, but it benefits from protective settings and routine care to avoid sharp impacts and abrasion from harder materials. The emerald cut’s trimmed corners help reduce vulnerability to chipping, and a setting that protects the corners, such as recessed prongs or a bezel design, is recommended for frequent wear. The heat treatment is permanent under normal conditions and does not require further enhancement for display or setting, making this stone a reliable choice for both collectors and connoisseurs seeking a technically well executed aquamarine with precise faceting, balanced proportions, and transparent, light blue coloration.
