Antique Jewelry or Estate Jewelry (or Estate Jewellery), in a formal sense, is jewelry and often timepieces which are part of the 'estate' of a deceased person. More specifically, the term refers to second-hand or pre-owned jewelry, with the 'estate' appellation signifying that the item is antique, vintage or an otherwise considered a significant or important piece.
Costume or fashion jewelry includes a range of decorative items worn for personal adornment that are manufactured as less expensive ornamentation to complement a particular fashionable outfit or garment as opposed to "real" (fine) jewelry, which is more costly and which may be regarded primarily as collectibles, keepsakes, or investments. From the outset, costume jewelry — also known as fashion jewelry — paralleled the styles of its more precious fine counterparts.
Jewellery consists of decorative items worn for personal adornment, such as brooches, rings, necklaces, earrings, pendants, bracelets, and cufflinks. Jewellery may be attached to the body or the clothes. From a western perspective, the term is restricted to durable ornaments, excluding flowers for example. For many centuries metal such as gold often combined with gemstones, has been the normal material for jewellery, but other materials such as glass, shells and other plant materials may be used.
A brooch is a decorative jewellery item designed to be attached to garments, often to fasten them together. It is usually made of metal, often silver or gold or some other material. Brooches are frequently decorated with enamel or with gemstones and may be solely for ornament or serve a practical function as a clothes fastener. The earliest known brooches are from the Bronze Age. As fashions in brooches changed rather quickly, they are important chronological indicators. In archaeology, ancient European brooches are usually referred to by the Latin term fibula.

A ring is a round band, usually made of metal, worn as ornamental jewelry. The term "ring" by itself denotes jewellery worn on the finger; when worn as an ornament elsewhere, the body part is specified within the term, e.g., earrings, neck rings, arm rings, and toe rings. Rings fit snugly around or in the part of the body they ornament, so bands worn loosely, like a bracelet, are not rings. Rings may be made of almost any hard material: wood, bone, stone, metal, glass, jade, gemstone or plastic. They may be set with gemstones or with other types of stone or glass.
