12.05 Ct. Heliodor from Madagascar

This transparent 12.05 carat cushion shape yellow heliodor measures 14.48 x 13.98 x 10.35 mm, and it has a mixed brilliant cut that marries a faceted crown with a carefully faceted pavilion to maximize scintillation and light return while preserving carat weight. The clarity is evaluated as eye clean at eye level, which means no inclusions are visible to the unaided eye during normal viewing, a quality that commands attention in a stone of this size. The color intensity is faint, offering a delicate, sunny hue that reads as refined and wearable for many settings. The polish is excellent, reflecting skilled lapidary work, and the gem has no enhancement, confirming its natural state. Origin is Madagascar, a source increasingly respected for producing fine beryl varieties, and The Natural Gemstone Company presents this gem with full disclosure of these attributes for the informed buyer.

The gemstone journey began in Madagascar, where the rough was recovered by local teams working in seasonally weathered alluvial deposits, and it then passed through hands that sorted and identified the piece for its potential as a large, clean crystal. The cutter selected a cushion shape with a mixed brilliant architecture to retain weight while opening the stone to lively brilliance and a broad table that displays the stone s hue and internal clarity. Each facet was executed to achieve an excellent polish, and the finished gem was inspected at eye level to confirm its eye clean clarity and unenhanced status. At The Natural Gemstone Company we worked directly with the cutter to document dimensions and the mixed brilliant cut, and to ensure responsible sourcing practices and traceability back to Madagascar. For the educated buyer this heliodor is valuable because of its combination of size, natural color, eye clean clarity, and the absence of treatments, all factors that influence long term desirability and market value. Its hardness and stability as a beryl family gemstone make it suitable for a variety of jewelry applications, and its classic cushion outline and excellent polish make it a strong choice for collectors and bespoke commissions seeking a naturally beautiful, responsibly sourced, statement gem.
