As an added bonus, the very small blade-like to acicular inclusions in the stone were identified as epidote. Get all the content featured in the most recent issue of Gems & Gemology, as well as access ...

Straight, acicular, colorless solid inclusions in demantoid garnet from the Ural Mountains of Russia were investigated by laser Raman microspectrometry. These “needles,” which occur in association ...

The University of Washington Institutional Review Board approved our crystal-prevalence study. Nineteen of the 40 prostates (47.5%) contained abundant, acicular (needle-shaped) birefringent crystals.

Areas far from the interface produced polygonal ferrite and pearlite, while areas close to the interface produced acicular ferrite and bainite. Chromium redistribution profiles are dependent on the ...

Results Acicular negatively birefringent crystals were abundant in eleven specimens. Additionally, positively birefringent, sometimes rhomboidal crystals, were often observed. By severity of ...

In fenite, monazite appears as acicular crystals, parallel to apatite’s crystallographic c-axis formed by exsolution from apatite by metamorphism. The data show that the monazite genesis was closely ...
