1.57 Ct. Aquamarine from Brazil

This 1.57 carat aquamarine from Brazil offered by The Natural Gemstone Company is presented in a classical emerald cut, with precise dimensions of 8.02 by 6.04 by 4.32 millimeters. The stone is transparent with a light color intensity and a clarity grading of very very slightly included, as evaluated at eye level. The cut displays truncated corners typical of a well executed emerald profile, and the overall proportions yield a length to width ratio of approximately 1.33, which preserves the rectangular geometry while maintaining an elegant face up presence. The gem has undergone controlled heat treatment to enhance its blue hue, and its surface polish is graded excellent, producing a mirror like finish on every facet plane. These measurable attributes combine to present a gem that reads as refined and technically exact, suitable for collectors and designers who require reliable specifications for setting and evaluation.

The cutting style is a defining element in the gem's optical performance, and the emerald cut employed here is executed to emphasize broad linear flashes and internal depth rather than extreme scintillation. The crown consists of broad step facets that lead to a relatively large table, creating planar reflections that emphasize hue and tone. The pavilion features parallel step facets extending toward a shallow pavilion angle, which produces the hall of mirrors effect that is characteristic of high quality step cuts. Given the refractive index range of beryl, approximately 1.577 to 1.583, and a low birefringence, the stone responds to light with calm, strong flashes of color rather than sparkling dispersion. The cutter has balanced facet widths and corner truncations to manage light leakage, and the facet junctions show symmetry that supports coherent internal reflection. The result is a controlled interplay of light and shadow, where each step facet acts as a channel for light to enter, reflect, and exit in broad luminous planes.

Clarity and enhancement play an important role in perceived brilliance, and this aquamarine benefits from minimal inclusions that do not interrupt the primary light paths. The very very slightly included grade at eye level indicates that internal features are either microscopic or positioned so that they remain visually unobtrusive when set. Heat treatment has been applied with restraint and technical oversight to reduce greenish undertones and to stabilize a cooler blue tone that reads clean in daylight and artificial light. The excellent polish amplifies these effects by minimizing surface scattering, allowing incident light to pass with minimal diffusion and to reflect from the stepped pavilion planes, producing pronounced linear flashes. The depth of 4.32 millimeters corresponds to a depth proportion near sixty one percent when referenced to the average of length and width, a proportion that favors balanced color saturation and optimal face up area. The cutter maintained careful pavilion geometry to avoid excessive shallow or deep angles that would otherwise compromise light return.

From a craftsmanship and application standpoint this aquamarine demonstrates attributes that make it exceptionally versatile for high quality jewelry. The combination of a stable heat enhanced blue, clean clarity, and precise step cutting yields a stone that will present consistent optical behavior across ring, pendant, or stud configurations. In settings, the stone will deliver broad, elegant flashes when light moves across the boarded facet planes, and it will show pleasing depth when viewed face on because of the well managed pavilion. For designers seeking an architectural aesthetic, the emerald cut provides a modern, refined language, and for collectors who prioritize technical excellence, the measured proportions and finish offer confidence in both appraisal and wear. The Natural Gemstone Company performs a final quality inspection and documents the stone origin, treatment, and measured proportions, and we can provide additional detailed photography and facet orientation diagrams on request to support design planning or certification needs. Care recommendations include avoiding harsh chemicals and extreme thermal shock, while routine cleaning with mild soap and warm water will preserve the polish and optical clarity over time.
