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

One transparent, emerald cut, lime green peridot, weighing 0.55 carat, with dimensions 6.04 x 4.00 x 2.73 mm. The stone displays medium color intensity, a clarity grade of very slightly included when evaluated at eye level, and an excellent polish. There has been no enhancement applied, and the origin is Ceylon Sri Lanka. As a member of the olivine group, this peridot derives its characteristic green from iron content within the forsterite fayalite solid solution. Typical gemological properties include a refractive index in the range of approximately 1.65 to 1.69, birefringence around 0.036, a specific gravity near 3.2 to 3.4, and a Mohs hardness of about 6.5 to 7. The emerald cut, executed with clean step facets and proportionate table and depth, emphasizes transparency and color uniformity, while the excellent polish contributes to precise facet junctions and consistent light return. The Natural Gemstone Company provides this gem with explicit attribution of untreated origin, and with clarity and finish grades that reflect in hand visual assessment.

Comparisons to historically renowned green gemstones illustrate how this peridot occupies a distinct place in the spectrum of collectible gems. The deep, chromium induced greens of classic Muzo emeralds and the historically famous emeralds of royal treasuries present a cooler, more saturated green that is typically accompanied by internal fissures and common clarity treatments. By contrast this peridot offers a warmer, lime green that appears more luminous and transparent at small to moderate sizes, and it is naturally untreated. The Dresden Green Diamond and the Hope Diamond are historical touchstones for green and blue green rarity, yet both are diamonds with distinctly different optical behavior, hardness, and scarcity profile. Garnets such as tsavorite and demantoid exhibit high dispersion and brilliance with a bluish green to pure green saturation, while peridot’s warmth and olive to lime notes remain unique because they are driven by iron rather than chromium or vanadium. Historically peridot has its own provenance in antiquity, with best known sources including Zabargad island historically associated with early crown jewels, and legendary associations with figures such as Cleopatra who is recorded to have prized island peridots. The peridot offered here echoes that legacy through its natural green tone and clear, step cut presentation, providing a distinct aesthetic that differs materially from emeralds, diamonds, and green garnets.

The unique value of this Ceylon peridot from The Natural Gemstone Company rests on a combination of provenanced origin, intact natural color, precision cutting, and eye level clarity. At 0.55 carat and with the elongated emerald cut proportions, the stone will present a controlled play of light and color, suitable for a ring center in a protective bezel or halo, or for a pendant where the color and transparency can be readily observed. The absence of enhancement enhances collector and designer confidence, since treatments such as oiling or dyeing are not factors in this gem’s presentation. From a practical perspective the hardness and toughness of peridot advising mindful setting choices and periodic care for daily wear, but its polish retention and stable color response to normal light conditions make it a durable option with proper mounting. For connoisseurs seeking a green gem that combines ancient provenance, straightforward gemological parameters, and a balanced visual presence, this Ceylon peridot represents a measured alternative to more heavily traded green stones. The Natural Gemstone Company documents origin, grading observations, and the untreated condition to support informed selection and long term stewardship of the piece.
