2.45 Ct. Cabochon Emerald from Pakistan

This specimen is a semi translucent oval green emerald weighing 2.45 carats, with exact dimensions of 10.39 x 8.85 x 3.71 mm, presented as a traditional cabochon cut. The oval ratio of 1.17 to 1.00 yields a visually balanced outline that reads slightly elongated without appearing narrow, a proportion that is well suited to both bezel and halo settings. The cabochon dome rises to 3.71 mm total depth, a profile that promotes even color distribution across the table and allows for controlled light transmission rather than faceted brilliance, which is appropriate for material of this clarity. Clarity is graded as slightly included at eye level, meaning inclusions are visible without magnification but remain well integrated into the stone, forming part of the character of the gem rather than significantly detracting from its appearance. Color is evaluated as medium intense, exhibiting a saturated emerald green that is neither too dark to mask internal features nor too light to lose presence, and polish is graded excellent, creating a smooth, mirror like surface on the dome that enhances luster and tactile quality. Enhancement is standard, and origin is Pakistan, provenance that informs both the typical inclusion patterns and the crystal habit seen in the cutting rough, details that The Natural Emerald Company documents for provenance minded clients.

From a technical perspective the choice of a cabochon over a faceted cut is driven by the material properties and the intention to maximize perceived color and depth. Cabochon cutting is less about faceting geometry and more about controlling dome curvature, symmetry along the major and minor axes, and the precision of the girdle or edge. The dome curvature on this piece is proportioned to minimize windowing and to avoid overly high domes that can create a glassy look with poor color saturation. The semi translucent nature of the material interacts with the medium intense saturation to produce a living green, where light entering the dome is scattered by internal features, creating depth and a subtle internal glow. Slight inclusions at eye level often take the form of short, thin growth structures and pinpoint crystals in Pakistan emeralds, and in this gem these features contribute to a dynamic texture when viewed under directional light. The excellent polish is significant, because cabochon surfaces transmit and reflect light differently than facets, and any surface irregularity would compromise the evenness of the glow. Under standard gemological evaluation, refractive index and specific gravity readings align with beryl class expectations, and these physical constants in combination with visible morphology are consistent with Pakistani origin.

Craftsmanship notes address both the cutting and post cutting treatment that define the finished presentation, and they outline practical considerations for setting and care that design professionals value. The cutting workflow begins with directional orientation of the rough to align the crystallographic long axis for optimal color banding, followed by successive grinding stages to establish the oval outline and dome profile, progressively finer sanding to remove scratches, and a final polish using cerium oxide or equivalent to achieve the excellent surface finish observed. Standard enhancement, applied prior to final polishing, improves the apparent clarity and stabilizes surface reaching fractures, which in practice makes the stone more suitable for daily wear when set correctly. For mounting, a low bezel or closed setting supports the cabochon perimeter and protects the girdle while allowing the dome to present color through the top, and designers often prefer warm metal surrounds to enhance the green saturation. Ultrasonic cleaning and harsh thermal shocks are not recommended for treated emeralds, and routine cleaning with warm water and a soft brush will maintain luster. The Natural Emerald Company stands ready to provide additional technical documentation, supplementary imagery under multiple light sources, and bespoke setting recommendations to integrate this 2.45 carat Pakistani emerald into a finished piece that honors both its geological origin and the cutter skill that shaped it.
