The pearl has a rich and vivid history. In south Asia, they are thought to have been drops of dew that fell from heaven into the sea. In ancient India, they were used by warriors as decorations on their swords to symbolically represent the fallen, and the sorrow brought by war. A pearl called The Wanderer is said to be the most gorgeous of all the pearls which was found by a slave and used to purchase his freedom in the early 1500’s.

Moonstones are believed to be sacred, and are displayed with utmost reverence as a bringer of good fortune from the spirit in the stone. Ancient Roman historians believed that the stone itself changed in accordance with the phases of the moon. They also thought it would bring them victory and that the essence of Diana, the goddess of the moon, was within the stones.

The alexandrite was named after the Prince regent at the time of its discovery in 1839, and is believed to bring about good luck. In Russia, alexandrite is very popular because of the way it reflects their national colors.

Today these three stones are excellent choices to represent the June birthstone, you can even choose two for the Gemini!

Rare Varieties

Black pearls, or Tahitian pearls are the rarest naturally occurring pearl as well as being the hardest to engineer. This is because they can only be nucleated one at a time, and black pearl oysters rarely produce pearls and white pearl oysters only rarely make the black pearl.
The rare asterism formation is very valuable in a moonstone and is usually seen in a four spoke star pattern. The rarest moonstones are highly translucent.

Alexandrite stones that show a very distinct color change like from red to green are highly sought after.

Origin of the words

Pearl in english comes from French, ‘perle’, which is derived from Latin, ‘perna’. Perna means leg and is from a resemblance of leg to bivalve.

The name ‘Moonstone’ comes from the physical appearance of the stone, by the sheen and optical appearance of this opalescent feldspar.

Alexandrite was named after Tsar Alexander II of Russsia. The first stone was said to have been found on his birthday in 1830 and named after him.

They have a pearly lustre, a white streak and an opaque transparency.

Moonstone is a type of feldspar from the silicate group with typical formula (Na,K)AlSi3O.Orthoclase and anorthoclase are examples of opalescent varieties feldspars which exhibit a blue to white sheen known formally as ‘schiller’. Schiller is a German word which translates roughly to having an iridescent or metallic lustre. Moonstones have a hardness of 6 – 6.5 on Mohs scale.

Alexandrite is a type of gem quality chrysoberyl that exhibits a particular color change habit from green to red depending on the lighting. The alexandrite variety of chrysoberyl exists due to having a high proportion of chromium ions in its structure, replacing some of the natural aluminium.
