Meanings of jacounce in inglês

One is the variety of red garnet known as almandine, and the other is the jargoon.

The almandine produces characteristic bands in the green and the jargoon in the red, green and blue portion of the spectrum.

In the case of jargoon, they are supposed to be caused by the presence of some uranium compound in the mineral.

Opal, which is a comparatively light mineral, has a low refractive power; zircon or jargoon is a heavy mineral, and has a high refractive power.

All the almandine garnets which I have examined, and nearly all the jargoons, show these characteristic absorption spectra.
