1.88 Ct. Aquamarine from Mozambique

One transparent 1.88 carat trillion shape aquamarine from Mozambique, dimensions 8.58 by 9.95 by 5.35 mm, presents a light blue hue with step cut faceting and an excellent polish, clarity evaluated as eye clean at normal viewing distance, heat treated to enhance color. The trillion form provides a contemporary triangular silhouette, while the step cut emphasizes broad, clean facet planes that convey an even, mirror like reflection rather than a highly scintillating surface. The combination of precise proportions and superior polish produces consistent light return across the pavilion and crown, which accentuates the gem's transparency and the tranquil, watery tone characteristic of aquamarine. This specimen is offered by The Natural Gemstone Company with documentation of origin and treatment, reflecting its provenance from Mozambique and the stable thermal enhancement applied to bring forward the stone's natural color.

When compared to more common gems, this aquamarine exhibits a different type of brilliance that distinguishes it in practical and aesthetic terms. Relative to diamond, which displays strong fire and intense scintillation due to higher refractive index and dispersion, this aquamarine produces a more subdued, even luminosity, with linear reflections that emphasize clarity and color rather than spectral flashes. Compared to corundum varieties such as sapphire, which often show deeper saturation and concentrated flashes from brilliant cuts, the aquamarine stands out through exceptional transparency and a cooler, lighter blue that reads as clean and serene on the finger. Against emeralds, which typically contain visible inclusions that interrupt light transmission, this eye clean aquamarine offers superior visual clarity and unobstructed light return, resulting in an appearance that reads as brighter and more open in typical viewing conditions. In relation to blue topaz, which can approach similar tones, the aquamarine's optical properties and step cut create a more refined, less glassy presentation, with facet planes that render a classic, architectural shimmer.

This gem's appeal lies in its balance of precise cutting, transparent material, and polished finish, producing an elegant, controlled brilliance that complements both contemporary and traditional settings. The Natural Gemstone Company presents this 1.88 carat trillion aquamarine as a specimen where clarity, cut, and natural color harmonize to deliver a distinctive, timeless blue.
