Congratulations, you've discovered an Emerald Gemstone in your candle!!
The name Emerald is derived from the Greek Smaragdus, which means "green gem". Emerald is one of the traditional four precious gemstones.
Colombia is the largest producer of Emeralds, followed by Zambia, but in the past they have been mined in Egypt, India, and Austria. It is the birthstone of May.
Emerald is a member of the beryl family, as is aquamarine, morganite and heliodor. Emerald has a hardness of 7.5-8 on the Mohs scale.
