4.00 Ct. Peridot from Ceylon (Sri Lanka)

This 4.00 carat oval peridot from Ceylon offered by The Natural Gemstone Company presents a measured elegance with dimensions of 11.07 by 8.95 by 6.04 millimeters, an elongated ratio of approximately 1.24, and an overall depth of approximately 60 percent relative to the average diameter. The pavilion and crown employ a mixed brilliant cut, with brilliant style facets on the crown paired to slightly modified step facets on the pavilion to maximize return of light while preserving table stability. The cutting geometry yields lively scintillation and well defined facet contrast, enhanced by an excellent polish and carefully executed facet junctions that minimize light leakage. Optical parameters consistent with gem quality peridot are present, including a refractive index range around 1.65 to 1.69 and visible birefringence near 0.036, with a specific gravity in the low 3.3 range and a Mohs hardness around 6.5 to 7. The color reads as intense green, with saturated tone and chromatic purity that responds well to directional light, and the stone has been heat treated to stabilize and intensify the green without compromising clarity or polish.

At eye level the clarity registers as slightly included, and the internal character defines the stone as much as the hue, producing an unmistakable signature for collectors and lapidaries. Distinctive inclusion features include small tabular negative crystals often surrounded by healed fracture halos that produce a subtle ringed or lily pad effect, sparse dark mineral crystals consistent with accessory chromite or spinel, and fine pinpoints and short fibrous needles that are dispersed rather than clustered. These inclusions sit within otherwise transparent body color and act as optical scatterers, creating localized flashes and a scattered bright sparkle under facet reflection while providing natural fingerprinting for provenance. The inclusion assemblage, combined with the intense Ceylon green, is characteristic of Sri Lankan peridot sources and offers a balance between eye visible individuality and gem trade acceptable clarity. For settings that favor natural character, the piece is ideal for bespoke jewelry where the interplay between precise mixed brilliant faceting and the stone s internal inclusions creates dynamic light return and a verifiable natural identity.
