An earring is a piece of jewellery attached to the ear via a piercing in the earlobe or another external part of the ear (except in the case of clip earrings, which clip onto the lobe).
Types of Earrings:
Stud earrings – The main characteristic of stud earrings is the appearance of floating on the ear or earlobe without a visible (from the front) point of connection. Studs are invariably constructed on the end of a post, which penetrates straight through the ear. The post is held in place by a removable friction back or clutch. Occasionally, the stud earring is constructed so that the post is threaded, allowing a screw back to securely hold the earring in place. This is useful in preventing the loss of expensive earrings containing precious stones or made of precious metals.
Hoop earrings – hoop earrings are circular or semi-circular in design, and look very similar to a ring. They are often constructed of metal tubing, with a thin wire attachment penetrating the ear. The hollow tubing is permanently attached to the wire at the front of the ear, and slips into the tube at the back. The entire device is held together by tension between the wire and the tube. Other hoop designs do not complete the circle, but penetrate through the ear in a post, using the same attachment techniques that apply to stud earrings. A variation is the continuous hoop earring. In this design, the earring is constructed of a continuous piece of solid metal, which penetrates through the ear and can be rotated almost 360°. One of the ends is permanently attached to a small piece of metallic tubing or a hollow metallic bead. The other end is inserted into the tubing or bead, and is held in place by tension. One special type of hoop earring is the sleeper earring. This is a very small continuous piece of (typically) gold wire which essentially hugs the base of the earlobe with the ends connecting in the back. Because their small size makes them comfortable, sleepers are sometimes worn at night to keep an ear piercing from closing.
Dangle earrings – Dangle earrings are designed to flow from the bottoms of the earlobes, and are available in various lengths from a centimeter or two, all the way to brushing the shoulders. They are generally attached to the ear by the use of thin wires, which go through the earlobe and connect to themselves in a small hook at the back. A variation is the French hook design, which merely hangs from the earlobe without closure, although small plastic retainers are sometimes used on ends of French hooks. Rarely, dangle earrings use the post attachment design.
Huggy earrings – Huggies are a popular style of earring where the setting actually ‘hugs’ your earlobe. These can come in different shapes and sizes, from hearts to rectangles. Many custom jewelers make huggy earrings because of the many varieties of setting that can be used to make a good template for their craft. Most times, stones are channel set in huggy earrings.
Slave earrings – The slave earring is also called a “Bajoran earring”, which became highly popular after it appeared on Star Trek.
Ear Thread – Or Earthreader, Ear String, Threader, a chain that is thin enough to slip into the ear hole, and come back out, dangles. Sometimes, people add beads or other materials on to the chain, so the chain dangles with beads below the ear.
Ear Spikes – A type of plastic stick 1 mm in diameter and 1.5 cm long that goes into the ear piercing. It does not fall out because it is slightly bigger than the piercing. It is quite popular amongst teenage and preteen girls in Hong Kong, as most schools do not even allow stud earrings.
