含鋰碧璽（Liddicoatite）是碧璽家族中稀少且美麗的成員，晶體橫切面層次分明、宛如彩繪般的色帶結構，主要產自馬達加斯加與巴西。其名稱源於「現代寶石學之父」、前 GIA 總裁 Richard T. Liddicoat，以致敬他建立 4C 鑽石分級制度與 D–Z 色階，為寶石學鑑定與教育奠定重要基石。

Liddicoatite is a rare and vibrant member of the tourmaline group, typically cut into crystal cross-sections to showcase their striking color zoning. Found mainly in Madagascar and Brazil, this gem was named in honor of Richard T. Liddicoat, the “father of modern gemology” and former GIA president.
Liddicoat revolutionized gemstone education by developing the GIA International Diamond Grading System™, which introduced the 4Cs of diamond quality and the D-to-Z color scale. His foundational Handbook of Gem Identification, first published in 1947, was used by gemologists worldwide and helped standardize gem identification across both diamonds and colored gemstones. The GIA Museum proudly showcases liddicoatite specimens, celebrating both the gem’s unique beauty and Liddicoat’s lasting impact on gemology.
