Florida State Gemstone or Gem



(KAlSi3O8 - Potassium Aluminium Silicate)

Adopted on May 20, 1970.

On May 20, 1970, Florida lawmakers passed and sent to the Governor a bill adopting the moonstone, (KAlSi3O8 - Potassium Aluminium Silicate,) as Florida official State Gem to commemorate the landing of U.S. astronauts on the moon. Apollo 11 had blasted off from the Kennedy Space Center in Brevard County, it came as no coincidence that the State Legislature sought to memorialize America's unprecedented international, scientific and technological triumph.

Ironically, the moonstone is not found naturally in Florida... nor was it found on the moon.

Moonstone: Florida State Gemstone or Gem


Moonstone is a sodium potassium aluminium silicate, with the chemical formula (Na,K)AlSi3O8. Its name is derived from a visual effect, or sheen, caused by light diffraction within a microstructure consisting of a regular succession of feldspar layers. The most common moonstone is of the mineral adularia. The plagioclase feldspar oligoclase also produces moonstone specimens. Moonstone is feldspar with a pearly and opalescent luster. An alternative name is hecatolite.

Moonstones come in a variety of colors. The body color can range from colorless to gray, brown, yellow, green, or pink. The clarity ranges from transparent to translucent. The best moonstone has a blue sheen, perfect clarity, and a colorless body color. It is often worn in rings, pendants or bead necklaces.

Colors: Colorless, white, yellow, orange, and gray. It always has a white or blue sheen.

Sources of moonstone: There are two moonstones. Adularia moonstone is an almost transparent pale gray or silvery white or blue shimmer. It is mainly found in Sri Lanka, Burma, India and Madagascar. Albite moonstone is in the feldspar group. It is semitransparent with a pale, shimmering reflection. It may be a little dull. It comes mainly from Canada.

JUNE Birthstone: Moonstone:


The third birthstone for June is the Moonstone. It was given its name by the Roman natural historian Pliny, who wrote that moonstone's appearance altered with the phases of the moon - a belief that held until well after the sixteenth century.

Moonstone has been used in jewelry for centuries, including ancient civilizations. The Romans admired moonstone, as they believed it was born from solidified rays of the moon. Both the Romans and Greeks associated Moonstone with their lunar deities. In more recent history, the moonstone became popular during the Art Nouveau period; French goldsmith Ren?Lalique and many others created a large quantity of jewelry using this stone.

A phenomenal gemstone, moonstones show a floating play of light (called adularescence) and sometimes show either a multirayed star or a cat's eye. Considered a sacred stone in India, moonstones often are displayed on a background of yellow (a sacred color) and are believed to encapsulate within the stone a spirit whose purpose is to bring good fortune. Part of the family of minerals called feldspar, moonstone occurs in many igneous and metamorphic rocks and comes in a variety of colors such as green, blue, peach, and champagne.
