Scientific Gemstone Properties of Emerald
Mohs Hardness of 7 -8 with a hexagonal crystal structure
Chemically, Emerald is a beryllium-aluminum silicate whose color is due to small quantities of chromium compounds. The Emerald is the green member of the Beryl Clan; sibling to Aquamarine (teal), Morganite (pink), Golden Beryl (yellow) and Heliodor (yellow green) as well as Bixbite (red) which is much more rare than the others.
The Flower for May is Lily of the Valley
Lily of the valley (Convallaria majalis) is a fragrant flowering plant used in religious ceremonies, world celebrations, perfumes and in gardens. Also known as the May lily, it means "return to happiness" and most often symbolizes chastity, purity, happiness, luck and humility.

The meaning of the color Green
Green, the color of life, renewal, nature, and energy, is associated with meanings of growth, harmony, freshness, safety, fertility, and the environment.

The Stone of Successful Love
Emerald derives its glorious green color from the presence of chromium and vanadium. Emeralds are rarely flawless, therefore stones are often enhanced by oiling them to hide the imperfects. As well, the step cut (or emerald cut) is used to maximize the stone.
Ancient mythology teaches us that the Emerald was associated with the Mercury, who was known to be the messengers of the gods, and of travel. It thus makes perfect sense that the Emerald is commonly referred to as the Travelers Protection Stone.
A lesser-known “odd” fact of the Emerald is that when subjected to heat, it will actually sweat or expel water. Ancient writings speak of this extraordinary phenomenon.
