Description

Great classic from Namibia - Topaz from Spitzkoppe is relatively rare - compared to Pakistan for example. And there is one indicator which makes the particular specimen even more special - it is the combination with smoky quartz! The topaz crystal is sharp terminated and all faces are very glossy, the smoky quartz is semi-lustrous and shows light brown color. The assemble is well balanced and aesthetic.
