PEARL-MOONSTONE-ALEXANDRITE

Pearls are the only gems found within living creatures, both salt and freshwater mollusks. However, most pearls on the market today are cultivated or cultured, since they now occur extremely rarely in nature. While pearls require special care, they have an enduring appeal for jewelry, particularly as the traditional June birthstone.

Color: Pearl color is the result of a body color and an overtone color or orient present as a lustrous sheen. The orient is the color seen as reflected by a diffuse light source. The rest of the color is due to the body color.
Crystallography: Amorphous. The aragonite in the nacre of a pearl is orthorhombic, with minute crystals radially oriented and a concentric structure.
Hardness: 2.5-4.5
Sources: Occurs naturally worldwide (but rarely); most pearls are cultivated.

Modern List – Alexandrite
“Emerald by day, ruby by night,” alexandrite is well-known for displaying one of the most remarkable color changes in the gem world — green in sunlight and red in incandescent light. However, this modern June birthstone is so rare and expensive few people have even seen a natural alexandrite.

What's the Birthstone for June?

This enchanting June birthstone originates from oceans, lakes and rivers around the world. It is a timeless wardrobe staple, beloved by women of all ages. The origin of pearls fascinated our forebears. Ancients from the Middle East believed that pearls were teardrops fallen from heaven. The Chinese fancied that the June birthstone came from the brain of a dragon. Christopher Columbus and his contemporaries thought that mollusks formed pearls from dew drops.

Moonstone is the best-known gem of the feldspar group of minerals. It is renowned for its adularescence, the light that appears to billow across a gemstone, giving it a special glow. The finest moonstones show a blue sheen against a colorless background. This June birthstone has been associated with both the Roman and Greek lunar deities. Hindu mythology claims that it is made of solidified moonbeams. Moonstone is often associated with love, passion and fertility; it is believed to bring great luck.

Alexandrite is the rare variety of the mineral chrysoberyl that changes color in different lighting. Most prized are those alexandrite birthstones that show a vivid green to bluish green in daylight or fluorescent light, and an intense red to purplish red in incandescent light. Major alexandrite deposits were first discovered in 1830 in Russia’s Ural Mountains. The gem was named after the young Alexander II (1818–1881), heir apparent to the throne. Alexandrite caught the country’s attention because its red and green colors mirrored the national military colors of imperial Russia.
Alexandrite was discovered in 19th Century Russia. It is the Modern Birthstone for June and was added to the U.S. list in the 1950s, but is incredibly rare. That is why Pearl is associated with June birthdays, as it is the Ancient Birthstone for the month. Pearl and Moonstone have been regarded as Birthstones for June since the early 1900s.
