13.04 Ct. Greenish Yellow (Lemon Quartz) Quartz from Madagascar

This beautiful transparent 13.04 carat radiant shape greenish yellow lemon quartz measures 17.59 by 12.92 by 9.36 mm, and displays a finely proportioned faceted radiant cut that maximizes scintillation and controlled light return. The material is graded eye clean when evaluated at eye level, with an intense color intensity and an excellent polish that enhances surface brilliance and edge definition. No enhancement has been applied to this stone, and its origin in Madagascar provides a useful provenance note for collectors, researchers, and lapidaries who value documented supply chains. The generous 13.04 carat weight combined with the radiant cut makes this gem especially attractive for center stone settings, museum quality creations, and sophisticated collections that demand size, color saturation, and workmanship.

Internal characteristics in quartz often serve as unique identifiers, and this lemon quartz is no exception, even though those features are not apparent to the unaided eye. Microscopic inclusions such as tiny mineral crystals, linear growth zoning, and fluid or two phase inclusions create a natural fingerprint that can be used to corroborate origin, to differentiate natural material from synthetic or treated alternatives, and to certify the stone under gemological examination. These internal markers can also enhance the gemological narrative of a piece, adding scientific interest and collectible value for educated buyers who consider provenance, natural formation processes, and traceable history when making an acquisition. For the discerning purchaser, the combination of eye clean clarity, intense color, substantial carat weight, excellent polish, and documented Madagascar origin represents a rare alignment of aesthetic and technical quality. The Natural Gemstone Company supports independent testing and can provide guidance on laboratory reporting, mounting recommendations, and long term care to preserve luster and color, ensuring that this radiant lemon quartz remains a verifiable and valuable component of any serious collection or bespoke jewelry commission.
