This type of jewellery can exude expense, but costs very little, usually over the top and ostentatious, it can be a main focus point of any outfit.

Originally, costume or fashion jewelry was made of inexpensive simulated gemstones, such as rhinestones or Lucite, set in pewter, nickel or brass. Modern costume jewelry incorporates a wide range of materials. High end crystals, CZs or cubic zirconia simulated diamonds, and some semi-precious stones are used in place of precious stones. Metals include gold- or silver-plated brass, and sometimes vermeil or sterling silver. Lower-priced jewelry may still use gold plating over pewter, nickel or other metals; items made in countries outside the United Kingdom may contain lead. Some pieces incorporate plastic, acrylic, or wood.

Many jewelers sell both costume jewellery as well as expensive pieces. H.Samuel a well known jeweler has a wide range to choose from, click on this link to see:

The term costume jewelry dates back to the early 20th century. It may reflect the use of the word "costume" to refer to what is now called an "outfit"; for example, a "handsome street costume of maroon brown velvet". Thus the jewelry worn with everyday fashion (costumes) grew to be known as "costume jewelry." Another theory is that the term refers to the jewelry worn in theatrical productions.

In many instances, high-end fashion jewelry has achieved a "collectible" status, and increases in value over time. There is a substantial secondary market for vintage fashion jewelry.
