4.67 Ct. Greenish Blue Tourmaline from Brazil

This is a beautifully transparent greenish blue tourmaline weighing 4.67 carats, a weight that immediately elevates its rarity and market value for educated buyers. The oval dimensions 11.43 by 9.59 by 6.16 millimeters give it an impressive face up presence, while the mixed brilliant faceted cutting style maximizes return of light and optimizes color saturation across the table. Medium color intensity delivers an attractive balance between vividness and wearability, and the excellent polish enhances scintillation without compromising the stone clarity. Clarity is described as very very slightly included when evaluated at eye level, a level of purity that is uncommon in stones of this size and contributes markedly to its desirability. Importantly this tourmaline has received no enhancement, a feature increasingly prized by collectors and connoisseurs who value natural state gemstones, and its documented origin from Brazil aligns with a long established provenance for high quality tourmaline material.

From a valuation perspective the 4.67 carat weight is a key determinant of value, because tourmaline prices per carat often rise steeply as stones move into larger size brackets, particularly when combined with strong clarity and natural color. The proportions indicated by the measurements produce a pleasing depth that supports optical performance and durability for a center stone in fine jewelry. The mixed brilliant cut creates an appealing blend of fire and color zoning control, making this gem suitable for a variety of settings from classic solitaire rings to bespoke pendants where the substantial carat weight reads as luxury and presence. For buyers who prioritize natural integrity and investment potential, this unenhanced Brazilian tourmaline stands out, as larger, clean, natural tourmalines are less common than their smaller counterparts. The Natural Gemstone Company is pleased to present this stone and can facilitate additional detailed photos, measurements, and independent verification upon request, ensuring transparency and confidence for the informed purchaser.
