4.96 Ct.Tw.Total Carat Weight Green (Lime Green) Peridot Pair from Ceylon (Sri Lanka)

This matched pair of Ceylon Sri Lanka peridots from The Natural Gemstone Company represents a scarce combination of precision cutting and closely matched optical characteristics, a rarity in the current market where finding stones that pair so well is uncommon. The two stones weigh 2.55 carats and 2.41 carats respectively, and are cut in a classical emerald shape with clean, rectilinear outlines. The face up dimensions are 9.04 x 6.95 x 4.73 mm for the larger stone, and 8.92 x 6.91 x 4.88 mm for the smaller stone. Both exhibit a lime green hue with medium color intensity, a clarity grade of slightly included at eye level, and an excellent polish. The pair has been heat treated, a standard and stable enhancement used to refine tone and remove minor undesirable overtones, and provenance is Ceylon Sri Lanka, a source known for producing bright, clean peridots with lively chroma. For connoisseurs seeking a matched set for a high quality pair of earrings or complementary side stones, the near equivalence in weight, table area, color intensity, and polish makes these stones exceptionally uncommon and valuable.

From a cutting and faceting perspective, the emerald cut chosen for these peridots is deliberately technical, favoring step facets and broad tablet planes that emphasize color homogeneity and clarity rather than scintillation alone. The step cut requires exacting control of facet plane parallelism and pavilion geometry, because improper angles can produce windowing or dead zones that dilute the vivid lime green. In these examples, the cutters prioritized a balanced crown to pavilion relationship to optimize light return, while maintaining a moderate pavilion depth to preserve the midtone color without causing excessive darkness in the pavilion. The long step facets on the crown and pavilion create clean linear flash, and the truncated corners reduce mechanical vulnerability while creating pleasing symmetry. Emerald cutting also accentuates any internal features, so the cutter oriented the optic axes to minimize birefringent doubling of facet lines in the face up view, a particular concern for peridot given its anisotropic optical behavior.

The material properties of peridot are relevant to both the selection and the cutting strategy used for these stones. Peridot is a member of the olivine group, with a chemical composition in the forsterite fayalite series, and it typically has a refractive index in the range of about 1.65 to 1.69 with a birefringence on the order of 0.036 to 0.038. Specific gravity for peridot falls near 3.2 to 3.4, and its Mohs hardness of approximately 6.5 to 7 informs both setting choices and care instructions. Peridot commonly exhibits weak to moderate pleochroism, and cutters will orient rough to present the preferred lime green axis to the table, maximizing perceived color saturation. The clarity grading of slightly included at eye level indicates small mineral inclusions or internal growth structures that do not detract from the stones face up appeal, but they are part of the optical fingerprint that allows these two stones to be well matched. The disclosed heat treatment has been applied to subtly improve color balance, and this treatment is stable under normal wear conditions.

In practical terms for jewelry design and finishing, the tight correspondence in color, size, and optical behavior makes this pair ideal for use as matched stud earrings or as paired accents flanking a central gem. Because emerald cuts emphasize clarity, the slight inclusions present were taken into account during cutting to position them away from the table whenever possible, thereby preserving a clean face up presentation. The excellent polish enhances facet reflectivity and allows the lime green color to read consistently under a variety of lighting conditions. For mounting, settings that offer protection to the corners such as low rubover bezels or four prong guards are recommended, to guard against impact on the truncated corners. Cleaning should be performed with warm soapy water and a soft brush, avoiding steam and harsh thermal shock, and ultrasonic cleaning is not recommended for stones with internal features. The Natural Gemstone Company stands behind the technical accuracy of these descriptions, and we note that finding a pair with such close matching in weight, dimensions, color intensity, cutting symmetry, and finish is rare, making this set a distinctive choice for collectors and designers who value technical precision and matched aesthetics.
