specimen number:
9302251

location:
Qinglong Mine, Dachang, Qinglong Co., Qianxinan, Guizhou, China

description:
An eye catching grouping of yellow green, platy carlheintzeite crystals measuring up to 0.4 cm gracefully arranged on matrix. The crystals display sharp, tabular forms and a vibrant coloration that stands out beautifully against the host rock, creating an attractive and well balanced composition. Carlheintzeite is a rare potassium sodium calcium silicate fluoride mineral, notable for its complex chemistry incorporating alkali elements and fluorine within its crystal structure. Its unusual composition and scarcity make well crystallized specimens particularly desirable among collectors of rare silicates. This example offers both strong visual appeal and mineralogical interest, representing a fine addition to any collection focused on uncommon species.
