0.85 Ct. Emerald from Russia

This transparent green emerald presents as a precisely executed princess shape weighing 0.85 carat, with calibrated dimensions of 5.52 by 5.07 by 4.21 millimeters. The near square outline is characteristic of a true princess profile, with a slightly longer length than width that enhances face up surface area. The pavilion depth of 4.21 millimeters yields an overall depth ratio of approximately 79.5 percent based on the mean of length and width, a proportion that concentrates color and delivers a saturated face up presence. The gemstone has been finished to an excellent polish, with crisp facet junctions and well aligned symmetry that preserve optical integrity across the table and crown planes. This stone has been graded as intensely colored, producing a vivid, uniform green that commands the eye, and it originates from Russia, a source noted for producing emeralds with steady saturation and a pleasing tonal balance.

The princess cut executed on this example follows a modified brilliant faceting schema optimized for beryl material, incorporating precise step like crown facets that transition to a series of chevron and pavilion facets which return color rather than scintillation. The cutter has emphasized clean facet planes and tight girdle geometry to minimize light leakage while maintaining strength at the corners. The table plane is sufficiently broad to showcase the intense color field, while crown facet angles are balanced to provide measured brilliance without dispersing the emeralds inherent hue. Craftsmanship quality is evident in the excellent polish across all facets, producing sharp light return and minimal surface disturbance under loupe inspection. These cutting decisions are intentional for emeralds, where preservation of color and reduction of windowing are primary goals for cut design.

Clarity is graded as very slightly included when evaluated at eye level, a designation that indicates minor inclusions are present but do not materially interfere with the stones overall visual appeal. In practical terms this means that the inclusions are small, well distributed, and generally stable, and that the face up appearance remains essentially clean with undisturbed color saturation. The enhancement is standard, consistent with trade practice for emeralds, and has been applied to stabilize surface reaching fissures and to optimize transparency. Standard enhancement treatments aim to fill microscopic cavities in a reversible manner to improve stability and reduce the visual impact of internal features. For the careful buyer, the practical effect of this approach is an emerald that reads as highly transparent and vibrant under normal viewing conditions, while retaining the natural character and internal architecture that collectors value.

From a durability standpoint this emerald belongs to the beryl group and registers at approximately 7.5 to 8 on the Mohs hardness scale, which provides good resistance to abrasion during normal wear. It is important to distinguish hardness from toughness, and to note that inclusions and fissures common to natural emeralds can affect impact resistance. Given the stones clarity profile and standard enhancement, prudent setting choices and handling will maximize longevity. For high exposure jewelry such as rings, protective settings that shield the corners and girdle are recommended, for example a bezel or robust prong architecture that reduces the risk of edge chipping. Routine cleaning with warm soapy water and a soft brush is appropriate, while steam, ultrasonic baths, and harsh chemicals should be avoided to preserve the enhancement and prevent potential damage. This green princess cut emerald from Russia, offered by The Natural Emerald Company, represents a technical balance of cut, color, and clarity, and is well suited for collectors and designers seeking a vivid, expertly finished gem with documented origin and responsible enhancement practices.
