The best of both world’s…
watch this stone change color in front of your eyes!

 

Color Change Garnet is a rare, phenomenal gem that changes color in front of your eyes. When you want two (or more) gems for the price of one…!

These gems are usually so light-sensitive that they display different colors in each different lighting condition.

The most significant changes in color are from florescent light (blues, greens, greys) to incandescent light (pinks, purples, reds). Daylight almost always shows a mix of each gem’s inherent colors, which can be considered a third color. Today’s newer LED lighting sometimes shows a fourth color too.

Color Change Garnets are rare above 2cts.

In January 2009 a ranch hand was digging a pit latrine in southeastern Kenya and came across some unusual looking stones just a few feet below the surface. He showed them to one of the local gem brokers who mistakenly identified them as Alexandrite.

What followed is the classic tale of mining rushes. Hundreds of small-scale miners descended upon the area from nearby mines and started producing rough gem material.

Color First was on location less than 3 weeks after the first strike and picked up some of the finest Color Change Garnets produced there. 

We wrote the article on it in Colored Stone GemMail (June 2, 2009). This is one of our favorite gems to work with.

Garnets are part of a large family of silicate minerals that have similar physical properties but vary in chemical composition.

Like most garnets these phenomenal gems are a mix of different species – in this case Pyrope, Almandine and Spessartine, same as Malaya Garnets, which are classified as Pyralspite.

The trace elements vanadium and chromium are responsible for the color change.

Small inclusions that are eye-visible don’t significantly affect the price when it comes to phenomenal gemstones like these – the beauty and strength of the change is far more important.

Garnet is the birthstone for January, celebrates the 2nd Anniversary and comes in almost all colors of the spectrum including this rare color-change material.

Lots of choice for January birthdays!
