1.67 Ct. Emerald from Colombia

This GRS certified natural Colombian emerald presents as a transparent, emerald cut stone weighing 1.67 carats, with exact dimensions of 9.02 by 5.99 by 4.46 millimeters, vivid color intensity, and a clarity grade of included as evaluated at eye level, enhancement recorded as standard, and an excellent polish. The emerald cut on this specimen is a classical rectangular step cut, with broad parallel crown and pavilion facets and truncated corners, a faceting style selected to emphasize color saturation rather than brilliance, to present large, even planes of vivid green across the table, and to reduce the visual impact of surface reflections. The GRS report documents origin as Colombia, which correlates with trace element signatures and growth zoning patterns typical of Colombian beryl, and the report confirms natural formation and disclosed enhancement, providing independent verification of provenance and treatment history. In practice, this combination of weight, proportions, and vivid green hue produces a strong face up color with controlled light return, making the stone ideal for a primary center gem application where color performance is the highest priority.

From a cutting and craftsmanship perspective the proportions are carefully managed to balance saturation and light transmission, the table facet and crown step planes are cut to maintain depth of tone while avoiding excessive windowing, and the pavilion steps are arranged to preserve an even color distribution through the stone’s body. The 9.02 by 5.99 millimeter footprint and 4.46 millimeter depth yield a depth percentage within the optimal range for emerald cut beryl, ensuring that the pavilion relays light into the crown facets to enhance perceived color rather than leaking light through a shallow pavilion. The step cut geometry and sharp girdle integrity help protect the truncated corners from chipping during setting and daily wear, while the excellent polish on facet junctions yields crisp facet reflections and a satiny luster that accentuates the stone’s vivid chroma. Clarity is graded included at eye level, and the internal features, commonly referred to as jardin in emeralds, form a characteristic three dimensional network of mineral inclusions and healed fissures, these features being intrinsic to natural Colombian emeralds and contributing to the stone’s identification, they also interact with facet planes to create depth and a distinct internal texture that cannot be precisely replicated by current growth technologies.

When compared to lab grown emeralds the distinctions are technical, observable, and materially significant for collectors and connoisseurs, lab grown material produced by hydrothermal or flux methods tends to exhibit far fewer internal features, more uniform color zoning, and growth patterns that are distinguishable under loupe or microscope and by spectroscopic analysis, whereas natural Colombian emeralds show complex inclusion suites, natural zoning, and trace element signatures that are consistent with primary crystallization in hydrothermal vein systems. From a gemmological standpoint the natural jardin carries diagnostic value, the three dimensional inclusion architecture in natural emeralds records pressure, temperature, and fluid conditions of formation, and these microscopic signatures yield a level of provenance and rarity that lab grown counterparts lack. Economically and culturally, natural Colombian emeralds continue to command premium pricing due to finite supply, historical desirability, and documented provenance, factors that support long term value retention, whereas lab grown stones offer excellent color uniformity and lower initial cost but do not provide the same provenance driven scarcity, nor the same market perception among collectors who value natural formation and certified origin.

At The Natural Emerald Company we document this stone with its GRS certificate, we disclose the standard enhancement as recorded on the report, and we present technical imagery and facet maps upon request to allow detailed inspection prior to purchase. For customers planning a setting we can advise on pavilion depth tolerances, bezel versus prong protection for the truncated corners, and mount orientation to exploit the stone’s pleochroism for maximum green saturation when viewed face up. This 1.67 carat Colombian emerald is a technically refined natural specimen, its emerald cut and excellent polish emphasize color saturation and protect against edge damage, its included clarity and natural jardin affirm its natural origin, and its GRS certification and documented provenance make it a superior choice for buyers who prioritize natural gemmological complexity and long term collector value over the uniform appearance and lower cost of lab grown alternatives.
