2.70 Ct. Green (Lime Green) Peridot from Ceylon (Sri Lanka)

This 2.70 carat oval peridot is an exacting example of modern lapidary control, measuring 10.05 by 8.00 by 5.14 millimeters, with an aspect ratio of 1.26 and a depth percentage of approximately 57 percent. The stone is cut as an oval with a mixed brilliant faceting scheme, a configuration chosen to balance sparkle with color saturation in a gem of this profile. The face up presentation is a vivid lime green with intense color intensity and transparent clarity, described as very slightly included when evaluated at eye level. The polish is excellent and the overall finish displays precise facet junctions and well aligned symmetry, traits that indicate careful preform orientation and controlled pavilion planning during the cutting process. Origin information is available, this peridot being from Ceylon Sri Lanka, and the material has received a controlled heat treatment to enhance and stabilize the lively green hue while maintaining natural transparency and internal character.

From a gemological and optical standpoint this peridot benefits from the mixed brilliant layout that places a brilliant pattern on the crown to maximize scintillation and a modified pavilion to reduce windowing and reinforce color return. Peridot refractive indices sit in the mid 1.65 range and the species exhibits moderate birefringence, which in a well oriented oval can be managed so that doubling effects are minimal in common viewing positions. The cutter has used pavilion angles and crown heights to produce an even face up brightness, allowing crown facets to break light into numerous small flashes while the pavilion arrangement prevents large dark areas. The excellent polish preserves facet demarcation, improving contrast and allowing crisp reflection outlines under magnification. The girdle and girdle plane have been finished to practical tolerances to facilitate secure mounting without adding unnecessary weight loss, and the culet is proportioned to avoid light leakage through the table.

Clarity wise the stone is visually clean with only very slight inclusions visible at normal viewing distances, inclusions that are typical of olivine group material and which do not interrupt the optical flow or the peridot s intense lime saturation. The heat treatment applied was used conservatively to reduce any brownish overtones and to deepen the green, a standard and stable enhancement when performed correctly. From a wearability and care perspective peridot rates around 6.5 to 7 on the Mohs scale, which means careful consideration is required for high exposure jewelry. For rings or bracelets expect to use protective settings and robust prongs or partial bezels to guard against edge nicks. Ultrasonic cleaners and steam treatments are not recommended for regularly treated or inclusion bearing peridot, and gentle warm soapy water with a soft brush is the preferred maintenance protocol to preserve both the stone and the applied treatment.

When designing a custom piece to showcase this peridot consider complementary gemstones and mounting strategies that exploit its intense lime tone and precise cutting. A classic choice is to frame the peridot with small round brilliant diamonds in a halo, using F to G color and VS clarity melee to provide high contrast while avoiding color contamination. For side stones consider tapered baguette diamonds to emphasize the oval s length, selecting cuts with shallow crowns to maintain a visual transition from the peridot s scintillation to the diamonds streamlined flashes. If color contrast is desired, pair the peridot with Ceylon blue sapphires in a soft cornflower blue, or with aquamarine in a light pastel blue, as these cool tones will sit opposite to the lime green on the color wheel and increase perceived vibrancy. For a warmer complementary palette pink to rose colored gems such as morganite or pink spinel will produce a lively but harmonious look, particularly when set in 18 carat yellow gold which amplifies the stone s warm green. For a contemporary aesthetic consider white metal mountings in platinum or 18 carat white gold and use knife prongs at the cardinal points to open the crown for maximum light entry and to show the mixed brilliant faceting to its best advantage. The Natural Gemstone Company can advise on precise matching sizes and cuts for side stones, recommend metal alloys and finishing techniques, and provide CAD visualizations to ensure that the peridot s proportions and optical performance are preserved in a finished ring, pendant, or pair of earrings.
