A green variety of quartz, Montezuma Prasiolite is known for its distinct green color. Prasiolite can range from a yellow-green to green. Deeper hues are preferred and are often considered more desirable.

It's very rare to find prasiolite that occurs in nature. The majority of material available on the market today is the result of treated stones. Montezuma Prasiolite is heat-treated. Typically, specimens of amethyst are used to produce this gem. Most heated amethyst becomes citrine. Very rarely, the heated stone turns into this delightful green gem.

Larger sized crystals are preferred for treatment. These bigger stones produce a finished gemstone with a more desirable, deeper green. Translucent, these gems are faceted into trendy modern cuts or traditionally calibrated sizes. The finished stones can be sensitive to heat, and should be stored out of direct light. Avoid exposing these precious jewels to sources of heat.
