Gemporia 3.22ctw Pink Fluorite & White Zircon Drop Earrings

Earring Back Types

Butterfly Back: A double looped piece resembling a butterfly that fits over a post. Variations on this design are called push back clasps. The basic post and butterfly back are usually used for stud earrings and lighter weight drop earrings.

Hinged Snap Backs: This clasp features a hinged post that snaps into a groove on the back of the earring. It is commonly found on hoops. Sometimes the hinged post is curved to provide more room to fit around the ear, sometimes called a saddleback.

Hook Backs: This earring backing is simply a long, bent post that fits through the piercing. Hooks have several variations, most notably the shepherd's hook and the French hook. While thin wire hooks reduce the weight of long earrings, making them more comfortable, they aren't as secure as other clasp styles.

Lever Back: A hinged lever snaps shut against the curved post to form a closed loop around the ear lobe. This clasp is very secure and good for large or medium sized styles that drop just below the ear.

Omega: Also called French clips, this clasp has a straight post and a looped lever. The hinged lever closes around the post and is held against the ear with pressure. The omega clasp is the most secure clasp, especially for the larger, heavier earrings.

Screw back: This backing is a slight variation of the standard post and butterfly nut back. Instead of pushing on the back, the nut twists onto the threaded post. A screw back post design is often preferred for expensive diamond stud earrings that require increased security.

Fluorite
Fluorite earns the reputation as the most colorful mineral in the world. A rich purple color is its most famous and popular color, but its range of colors can be extremely variable with hues of blue, green, yellow, colorless, brown, red, pink, black and reddish orange. Intermediate pastels are also possible. Fluorite’s colorless variety is a rare find that makes it highly sought-after by collectors. Its brown variety features a distinctive iridescence and the more rare colors of rose and black are very attractive and in high demand. Most fluorites have a single color, but some have multiple colors that are arranged in bands or zones corresponding to the shapes of their crystals. A single crystal of fluorite could potentially have four or five different colors. Prized for its glassy luster, its crystals range from transparent to translucent.

Fluorite is strongly fluorescent with extremely variable colors. Typically it fluoresces blue or violet, but other fluorescent colors include yellow, green, red and white. It has a hardness of 4.0 on the Mohs Scale and has been known to fade in the sunlight. The mineral is found throughout the world, including Canada, Mexico, Brazil, Morocco, South Africa, Europe, Mongolia, China and Russia. In the United States, the states in the Mississippi Valley, especially Illinois, Kentucky and Ohio, have historically contained the largest deposits, but Colorado also has ample deposits of fluorite, as well.

The word fluorite comes from the Latin word meaning “to flow.” For centuries, the ancient Egyptians and Chinese used fluorite in carvings. Carved ornaments were even recovered from the ruins of Pompeii. Fluorite today is believed to be a spiritual stone that excels at calming the spirit and mind. Used as flux in the smelting of metallic ores , fluorite was originally referred to as “fluorspar” by miners and is still called that today.
