4.69 Ct. Blue Aquamarine from Brazil

This pear shape blue aquamarine is a transparent, faceted gem weighing 4.69 carats, with exact dimensions of 12.70 by 9.25 by 7.12 millimeters, and a mixed brilliant cutting style that balances scintillation and color retention. The clarity is evaluated as very very slightly included at eye level, a high clarity grade for a stone of this size, and the polish is excellent, which enhances return of light and surface brilliance. The color intensity is medium, yielding a pleasing, classic sea blue that is both wearable and collectible. This aquamarine is heat treated, a standard and stable enhancement that deepens blue tones without compromising durability, and its origin is Brazil, a source noted for producing clean, attractively colored aquamarines. The Natural Gemstone Company presents this gem with full transparency about its characteristics to support informed purchasing decisions.

Under varied lighting conditions this aquamarine will display distinct but consistent appeal. In bright daylight and direct sunlight the medium blue will appear lively and more saturated, while the mixed brilliant facets will produce strong flashes of white sparkle, emphasizing brilliancy and outline. Under cool LED or fluorescent lighting the stone’s blue may read slightly cooler and crisper, with facet definition that highlights the mixed brilliant cut. Under warm incandescent or halogen lighting the blue shifts toward a softer, warmer tint and the stone will show a gentle glow, useful when paired with warm gold settings. In low light or candlelight the excellent polish and the cut still provide subtle scintillation and a focused flash from the table and crown facets. Aquamarine can exhibit weak to moderate pleochroism, typically showing slightly different intensities of blue to greenish blue when viewed from different angles, and that optical character is accentuated by the pear shape and mixed brilliant faceting for visual depth.

For educated buyers this gem’s value derives from the balance of size, clarity, and color, along with an industry accepted heat treatment and Brazilian provenance that together justify its price position relative to comparable beryl specimens. The stone’s 4.69 carat weight and very very slightly included clarity make it well suited for a centerpiece ring or pendant, offering both presence and wearability with a Mohs hardness of about 7.5 to 8. For customers considering complementary material, White Opal is a light body tone opal known for its soft play of color and iridescence, which contrasts beautifully with aquamarine blue when used in mixed gemstone designs.
