The almandine produces characteristic bands in the green and the jargoon in the red, green and blue portion of the spectrum.
It seems related to both almandine and pyrope, and shows the absorption-spectrum of almandine.
almandine, al′man-dīn, n. a red transparent variety of the garnet.
One is the variety of red garnet known as almandine, and the other is the jargoon.
Almandite garnet, the "almandine" of the jeweler is less abundant than pyrope, when of gem quality.
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.
almandine garnets also show no dichroism and lack variety of color.
After quartz come corundum (Oriental amethyst), spinel (almandine spinel), garnet (almandine), and spodumene (variety kunzite).
