2.50 Ct. Emerald from Zambia

One transparent 2.50 carat oval green emerald from Zambia, with dimensions 10.00 x 7.45 x 5.59 mm, presents a concise combination of size and presence that suits a wide range of custom jewelry designs. The gem is fashioned with a mixed brilliant cut, yielding a lively internal reflection pattern while maintaining the generous face up area and elegant silhouette characteristic of the oval form. Clarity is graded very slightly included, evaluated at eye level, which preserves a clean visual field and allows the vivid color intensity to remain the defining attribute. The polish is excellent, and the stone has received standard enhancement, a practiced treatment that stabilizes clarity and surface appearance while preserving the natural origin characteristics associated with Zambian emeralds.

In hand, this emerald projects a saturated, vivid green that reads clearly against both skin and metal, with lively scintillation delivered by the mixed brilliant facet arrangement. The depth of the stone at 5.59 mm provides balance, preventing a flat or windowed appearance while enhancing internal light return. Face up the gem displays rich color uniformity with the moderate inclusions contributing to depth rather than distracting from color. When set in a table focused setting, the stone presents a consistent color across viewing angles, and the very slightly included clarity grade supports pavillion reflections that add a subtle three dimensionality to the green, rather than opaque areas or excessive light leakage.

For custom settings, consider pairing this emerald with colorless diamonds to emphasize contrast and brilliance, small round brilliant melee diamonds forming a halo will uplift the vivid green while maintaining a refined, high contrast presentation. Side stones in tapered baguette diamonds will accentuate the oval axis, elongating the profile and adding geometric refinement. For a warmer, vintage inspired composition, select 18 carat yellow gold as the metal of choice, the gold warmth will enrich the green and create a classical aesthetic, whereas platinum or 18 carat white gold will produce a cooler, contemporary contrast that accentuates brightness and perceived saturation. Rose gold can be used selectively in mixed metal designs to introduce a soft, romantic backdrop that tones the green slightly, creating a more subdued, antique feeling.

Complementary colored gemstones can be used to create distinctive color relationships, blue sapphires will form an analogous cool palette that harmonizes with emerald green, while fancy yellow sapphires or cognac diamonds will introduce complementary contrast that intensifies the green through visual juxtaposition. Paraiba tourmaline or small tsavorite accents selected for matching saturation can create layered green tones, building depth and complexity across the design. Consider pairing the central emerald with single cut diamonds in the gallery and underbezel to allow light to bounce back up through the crown, enhancing brightness without overwhelming the green. When choosing accent sizes, rounds from 0.01 to 0.05 carat are typical for halos and pavements, while side stones of 0.10 to 0.50 carat each are suited for three stone interpretations, select proportions that respect the 10.00 x 7.45 mm footprint to preserve balance and wearability.
