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

This 4.06 carat oval peridot from Ceylon Sri Lanka presents an immediate visual appeal, with a bright lime green hue and transparent body color that registers as intensely saturated. The gem measures 11.18 x 9.22 x 5.90 mm, with proportions that translate to a depth percent of approximately 57.8 percent. The mixed brilliant cut has been executed to emphasize both scintillation and color distribution, and the surface shows an excellent polish that allows the eye to move freely over the stone without distraction. Slightly included, evaluated at eye level, this peridot nevertheless displays a clean window of transparency that lets the internal green tone project strongly. At The Natural Gemstone Company we describe this stone in precise, technical terms so that an educated buyer can assess both aesthetic and investment characteristics with confidence.

The mixed brilliant cut on this oval peridot is central to how the gem interacts with light, and it has been chosen to optimize the material properties of olivine. In a mixed brilliant style the crown is faceted in a way that resembles a brilliant pattern, dispersing incoming light into lively flashes and maintaining broad white light return, while the pavilion is configured with a controlled combination of brilliant and modified facets that manage internal reflection. The effect is a lively play between brilliance and flash, rather than a narrow sparkling that would favor fire alone. Because peridot has a refractive index in the range of roughly 1.65 to 1.69, and a measurable birefringence near 0.036 to 0.038, facet angles and pavilion depth are important to avoid light leakage and to preserve both brightness and color saturation. The present proportions and facet arrangement preserve return light to the viewer, producing a vivid face up appearance where the lime green reads with evenness and vibrancy across the table, and where the polished facet junctions add sharp, crisp reflections that enhance perceived clarity.

The clarity grade for this gem is slightly included at eye level, a realistic and common grade for peridot material of this size and color, and one that should be interpreted with nuance by a knowledgeable buyer. Slight inclusions in peridot often occur as fine crystals or healed fractures and can be characteristic markers for natural origin. In this specimen the inclusions do not materially disrupt the overall transparency or color saturation when viewed in typical jewelry settings. The excellent polish contributes to a visual impression of depth, because well executed polishing minimizes surface scattering and allows internal light paths to remain coherent, thereby maximizing apparent brilliance. The stone is transparent, and under standard daylight balanced illumination the intense lime green is dominant, while the internal reflections generated by the mixed brilliant faceting produce secondary flashes of lighter and deeper green that animate movement.

Regarding enhancement and provenance, this peridot has been heat treated, a disclosure we provide openly because transparency about enhancements is essential for trust and accurate valuation. Heat treatment in peridot is used to refine tone and to remove or reduce secondary brownish or yellowish undertones that can otherwise mute green intensity, and this treatment is generally stable and accepted in the trade when disclosed. The origin of the gem is Ceylon Sri Lanka, a source that is respected for producing a wide range of fine colored stones and that contributes to the gemology narrative for collectors and connoisseurs. Origin can influence buyer perception and market positioning, and Ceylon Sri Lanka provenance for a vivid, well cut peridot is a positive attribute that supports both desirability and potential resale interest. Taken together, the intense color, attractive size at 4.06 carats, transparent body, mixed brilliant cut, and disclosed stable heat treatment form a profile that is both aesthetically compelling and logically priced for an informed buyer.

For practical use and care, this peridot is an excellent candidate for a variety of jewelry applications, including a center stone in a ring, a substantial pendant, or a bespoke piece that highlights the oval silhouette and lively green tone. Given peridot hardness around 6.5 to 7 on the Mohs scale, we recommend settings that protect the girdle and allow the pavilion to remain accessible for light performance, such as a four prong or partial bezel design that still permits light to enter the crown. Routine care should avoid harsh chemicals and extreme heat, and cleaning with warm soapy water and a soft brush is sufficient for maintaining the polish and brilliance. At The Natural Gemstone Company we stand behind the description and condition of this peridot, and we present it with full disclosure on cutting, clarity, enhancement, and origin so that an educated buyer can evaluate its technical attributes alongside its visual impact. This combination of documented grading, careful cutting to maximize light return, and well communicated provenance is what makes this peridot an attractive choice for both designers and collectors seeking a gemstone of substance and character.
