I think the easiest way to classify bracelets is by the way their style, as all bracelets can be divided into one of two major groups: flexible bracelets and non-articulated ones. Flexible types of bracelet are most common, as they are comfortable and versatile to wear. They can be divided by style as follows:
These types of bracelets are made up of several links, sometimes identical and sometimes varying in shape and length, with the metal in one colour or more. Sometimes they are encrusted with gemstones to give a simple piece a more luxurious appearance, but for the most part their are found in a design of pure metal.
A composite band whose main feature is a chain with large links. There are removable charms on the chain, normally in the form of beads or pendants. Occasionally these small accessories are a non-removable detail and are part of the bracelet chain.
As the name suggests, this item for the wrist is made of several decorative components connected to one another to form the whole bracelet. The linking components are usually gems, beads or feature-points moulded from precious metals. Many jewellery companies develop their own original linking components, as well as their own techniques to attach the feature-points to one another.
This could be said to be a variant of the link bracelet, and it has already become a classic. The tennis bracelet contains stones of the same caliber, more often than not white diamonds, that encircle the wrist with a sparkling halo. To achieve a seemingly seamless effect, the clasp on this type of bracelet is usually hidden from view.
Slave or Harem bracelet
This type of bracelet can be broad enough to cover the wrist or be in the form of a thin chain, but in both cases it is coupled with one or more rings, hence, in all probability, the name. In India, this sort of bangle can often be seen on the bride’s wrist at her wedding ceremony, though in Europe it is a fashion accessory.
Hard bracelets are rigid in structure and come in the form of an open or closed ring.
A wide, popular bracelet made of metal, stones and other materials, that covers the wrist like the cuff of a shirt. Its large size gives designers free reign of imagination, meaning they can decorate the cuff’s surface with gemstones, enamel ornamentations, golden patterns, engravings, and cuttings of mother-of-pearl. There are many, many options.
The bangle is a non-articulated bracelet that may or may not have a clasp. It is another fashionable piece of jewellery for the wrist, but it differs from the cuff in that it is thinner – much thinner in fact. These bracelets are often worn many at a time, making for a stylish, jingling combo.
A thin bracelet which looks very similar to a bangle, but with an open inner section, lending it the alternate names of the “open bracelet” or “half bangle”. The design enables it to slide along the narrower part of the wearer’s arm. Typically, the half bangle comes in various widths and tends to be more comfortable when worn alone (or in combination with pliable bracelets).
The snake bracelet is a spiral spring bracelet without a fastening that fits snugly around the wrist and forearm. Jewellers create it using a special technique with gold to make the metal malleable, or they make the item from a large number of tightly interlocking, bendable links.
This is a hybrid between a bracelet and a ring, and is worn on the palm, with the decorative part on the outer part of the hand. The palm bracelet goes in and out of fashion, and is not to everyone's taste because of the unconventional way that it is worn. However those who are brave enough to follow this trend are rewarded with compliments galore!
Of course, an even more detailed classification of bracelets could be done, looking at them by type of clasp or by the materials used to make them. However, I see no need for this, as all those items would lend themselves to the categories above.
