Historical Examples of almandine
Almandine, al′man-dīn, n. a red transparent variety of the garnet.
It seems related to both almandine and pyrope, and shows the absorption-spectrum of almandine.
The almandine produces characteristic bands in the green and the jargoon in the red, green and blue portion of the spectrum.
In this way we are enabled to identify a jargoon or an almandine merely by looking at it.
All the almandine garnets which I have examined, and nearly all the jargoons, show these characteristic absorption spectra.
