1.32 Ct. Tourmaline from Ceylon (Sri Lanka)

One transparent 1.32 carat oval green tourmaline, dimensions 8.06 x 6.11 x 3.66 mm, presents a balanced and elegant profile that is ideal for a refined engagement setting. The gem has been fashioned into a mixed brilliant cut, combining a broad table and carefully arranged crown facets with a precision modified pavilion that optimizes both color saturation and light return. Clarity is described as very very slightly included when evaluated at eye level, which means inclusions are minimal and do not distract from the gem under normal viewing. Color is medium light in intensity, exhibiting a fresh, verdant green that reads as lively under natural daylight and becomes more saturated under warm artificial lighting. The polish is excellent, with crisp facet junctions and a clean surface finish that enhances both transparency and brilliance. Origin is Ceylon Sri Lanka, and there is no enhancement, offering the certainty of a natural untreated gem from a well regarded gem producing region. The Natural Gemstone Company offers this stone with full disclosure of its characteristics, and it is presented as a premium choice for personalized engagement jewelry.

Technically, the mixed brilliant execution on this oval tourmaline has been calibrated to the stone proportions, with depth at 3.66 mm yielding a depth ratio of approximately 51.6 percent relative to the mean diameter, a proportion that produces a broad table and a lively face up appearance. The mixed approach typically features a brilliant style crown to disperse light effectively, paired with a modified pavilion to control windowing and to deepen perceived color without sacrificing scintillation. Facet symmetry is consistent across the girdle, and the table is well centered, which maintains even light distribution and minimizes the risk of light leakage. Tourmaline has a refractive index in the range of approximately 1.624 to 1.644, with birefringence typically between 0.014 and 0.020, characteristics that contribute to the stone s distinct sparkle and optic character. The excellent polish further maximizes these optical properties, ensuring clean facet return and crisp internal reflections that are desirable in a center stone intended for daily wear.

Color and clarity interplay in this gem to deliver refinement rather than flash, with the medium light green offering versatility across metal choices and design styles. The green displays subtle pleochroism typical of tourmaline, meaning different green tones become more apparent when the stone is viewed from alternate angles, adding depth and life to the face up presentation. Because this specimen is untreated, the color is intrinsic to the crystal chemistry and the geologic conditions of its Ceylon provenance, which is known for producing gem quality tourmalines with attractive hues and good clarity. The very very slightly included clarity grade indicates that inclusions are small and generally not visible to the naked eye at normal viewing distance, preserving both transparency and durability. With no evidence of enhancement, the gem retains natural stability and a predictable response to light, which is important when combining the stone with accent diamonds or metal settings that alter visual contrast. The tourmaline s dispersion is modest, which means fire will appear restrained compared to diamond, but the stone compensates with vibrant body color and lively facet scintillation.

For an engagement ring application this oval green tourmaline is an excellent candidate, offering a combination of size presence and wearable toughness. Tourmaline rates approximately 7.0 to 7.5 on the Mohs scale of hardness, and with prudent setting choices such as a protective bezel, sturdy four prong head, or a low profile halo the stone will perform well with daily wear. Design options include a classic solitaire in yellow gold to warm the green and emphasize its natural tones, a platinum or white gold mounting to present a contemporary contrast and to highlight the gem s clarity, or a vintage inspired halo with pavé diamonds to enhance perceived size and sparkle without overwhelming the primary color. Because the gem is natural and untreated, avoid high heat and prolonged exposure to strong sunlight that may subtly affect color over extended periods, and clean with warm soapy water and a soft brush for routine maintenance, while avoiding steam and ultrasonic cleaning when inclusions are present. The Natural Gemstone Company is pleased to offer this natural Ceylon green tourmaline to clients seeking a distinctive and technically refined center stone for an engagement design, and we can provide further gemological details and bespoke setting recommendations upon request.
