1.80 Ct. Emerald from Colombia

Presenting a transparent 1.80 carat asscher octagonal green emerald, a gem that balances substantive carat weight with refined proportions. The stone measures 7.88 x 7.20 x 4.82 mm, dimensions that translate into a commanding face up presence for its carat class while retaining classic wearable proportions. At 1.80 carat the gem occupies the sweet spot between medium and larger sizes where color and presence dominate perceived value, and where precision cutting and material quality are most readily appreciated. The Natural Emerald Company offers this specimen as an example of how carat weight, when paired with exceptional color and cutting discipline, becomes the principal determinant of premium classification. The purely numerical mass of 1.80 carat is therefore not an isolated metric, but a component of an integrated assessment that includes table area, depth profile, and optical performance, all of which are optimized in this asscher formation.

The asscher cut in this example is executed as a true octagonal step cut, featuring broad, shallow crown facets and concentric pavilion steps that emphasize color straightness and internal light flow. Asscher faceting differs from mixed or brilliant approaches in that it relies on parallel facet planes to produce a hall of mirrors effect, a visual phenomenon that in this emerald accentuates the vivid green body color while revealing depth through repeating planes. Given the measured dimensions and the pavilion height of 4.82 mm relative to the average of the length and width, the depth percentage is approximately 63.9 percent, a proportion that supports controlled light return without sacrificing the saturation that defines premium green stones. Facet junctions are executed to tight tolerance so that facet planes align with precise symmetry, and this disciplined faceting strategy is particularly effective in an asscher layout where small deviations quickly translate into visible asymmetry.

Clarity assessment for this example is slightly included, evaluated at eye level, which for emeralds denotes the presence of natural internal features that are visible with unaided sight but do not materially compromise structural integrity when properly handled and set. Slightly included in an emerald context is often preferable to excessively cleared material because the internal network is an inherent character of emeralds and contributes to the stone identity. The enhancement is standard, consistent with established industry practice for Colombian emeralds, and has been applied to optimize clarity and stability without altering the intrinsic color. The color intensity is vivid, a saturation level that conveys strong, lively green with the clarity and medium to medium deep tone that collectors and connoisseurs associate with Colombian origin. Origin provenance from Colombia is significant because it correlates with a historical range of chromatic nuances and crystal habits that respond exceptionally well to refined step cutting.

Craftsmanship attributes include an excellent polish and a well balanced girdle profile that facilitates secure setting and minimizes unnecessary material removal during mounting. The table facet is centered and proportioned to harmonize with the crown angle and step sequence so that the asscher signature of parallel flashes is maintained across viewing angles. For buyers prioritizing carat driven quality, the 1.80 carat mass combined with the vivid color and precise asscher faceting positions this emerald in a premium tier, offering both visual impact and collector appeal. The Natural Emerald Company stands behind this stone with full disclosure of proportions, clarity evaluation, enhancement status, and origin, and we can provide additional images and viewing options for clients who wish to assess face up color and step patterning in situ.
