Red/Pink Garnets Without The Brown Colour Shift

[pwsg07]

I have purchased two red garnets online. The problem I have with red garnets is that they shift to brown under certain lighting. Which variety of red garnet that shifts to a more pleasant colour such as purple? If there was any thread that is about this topic, please let me know. Thanks in advance.

Hello. This is what i found on the AJS Gems website.

Rhodolite is the finest of the red garnets, with a color that ranges from rose to raspberry, without a trace of the brown secondary hue found in the common garnets. Hope this helps.

Thanks Tsavomn. Actually the two garnets I have is rhodolite and pyrope. They both look brownish under CFL. Rhodolite looks good under sunlight but the tone is close to dark.

My umbalite garnets don't shift to brown. They lose their lovely sparkle under one type of lighting, but no shifting to brown.

There are red and pink garnets that don't become orange or brown but they are very uncommon. It isn't limited to a specific type but on a stone by stone basis.

Not true about all rhodolite.

The issue here isn't really the garnet, it's the light source. Maybe the worst invention of the past 20 years is the CFL light bulb. These bulbs can not produce true colors, since they lack so much of the visible light spectrum.

In the image below showing various light bulbs as viewed through a spectroscope, you can see the 3 CFL bulbs in the center lack much of the visible spectrum. These missing wave lengths cause the tremendous shift in colors you see, which are in many cases not good shifts. Red stones, especially garnets seem to suffer the most, while peridot and chrysoberyl are a few of the stones that seem to benefit from the reduced spectrum.

Do your self a favor, and purge your home of these intruders!

Thanks chatoyancy, Chrono, TL, and Gene.

Does ruby look brownish under CFL? How do peridot and chrysoberyl benefit from the CFL? Do they look greener under CFL?
