2.75 Ct.Tw.Total Carat Weight Peridot Pair from Ceylon (Sri Lanka)

This paired set of Sri Lankan peridots from The Natural Gemstone Company presents a rare combination of precise cutting, intense color, and clean clarity, ideal for an educated buyer seeking both aesthetic appeal and gemological integrity. The stones weigh 1.35 carats and 1.40 carats respectively, and their oval outlines measure 7.95 x 5.97 x 4.29 millimeters and 8.11 x 6.07 x 4.12 millimeters. Each gem has been given a checkerboard pavilion and crown treatment which multiplies reflective planes, and both stones have an excellent polish, which maximizes light return across their surfaces. Clarity is graded as very slightly included, evaluated at eye level, a designation that indicates only minor internal features that do not interfere with overall brilliance or beauty. The peridots show intense color intensity, a lively lime to olive green that is a hallmark of high quality peridot, and they are heat treated to enhance and stabilize that desirable hue. Origin is Ceylon, Sri Lanka, a locality respected for producing peridots with lively saturation and generally good clarity, and this provenance adds to their appeal for collectors and designers who value documented origins.

From a light performance perspective, these peridots are compelling because of how their material properties and cutter choices interact to create a vivid play of surface and internal reflection. Peridot has a refractive index in the range of about 1.65 to 1.69 and a modest birefringence, which together produce distinct internal flashes and a well defined outline to facet reflections. The checkerboard cut multiplies plane facets across the table and crown, producing a mosaic of mirror like surfaces that emphasize surface brilliance and scintillation more than fire, which is naturally limited by peridot s lower dispersion. The excellent polish ensures that those facets act as efficient mirrors, reducing surface diffusion so that light entering the stone is returned as sharp flashes and saturated color. Because the two stones are closely matched in tone and saturation, their reflective behavior is complementary. Slight differences in dimensions create a subtle variation in the angle and timing of flashes, so when paired in earrings or a matched design they create a dynamic visual interplay, each stone reflecting and echoing the other s light. The very slightly included clarity means there are minimal internal features, and when present these inclusions are small and isolated, occasionally acting as microscopic scattering centers that can enhance micro scintillation without compromising transparency.

When considered as a matched pair for fine jewelry, these peridots offer both practical and aesthetic advantages that justify their value to a discerning buyer. The intense, even color and excellent polish mean that open backed settings, such as prong mounted earrings or open gallery studs, will allow optimal light entry and the maximum expression of color and brilliance. The checkerboard cut also reduces the visual impact of minor size mismatch, because the multiple reflective planes distribute light evenly and create an appearance of cohesion between the two gems. Heat treatment, disclosed and stable, is an accepted enhancement that improves color uniformity and long term stability, and the Sri Lankan origin supports a traceable supply chain that is important to informed purchasers. For care, warm soapy water and a soft brush are recommended, avoiding harsh chemicals and ultrasonic cleaners that could stress certain settings, and periodic inspection of the mount will preserve the stones integrity and light performance. At The Natural Gemstone Company we source and present gemstones with full disclosure of origin and enhancement, and these peridots exemplify how careful cutting, excellent polish, and responsible treatment combine to produce a matched pair that is both technically sound and visually captivating, making them a smart choice for custom jewellers, collectors, and anyone seeking a distinctive green that reads as both modern and refined.
