ri·vi·ere | ˌri-vē-ˈer
noun
A choker-style necklace that is a continuous line of gemstones usually of graduated or equal size stones
A riviere is a style of necklace that was popular in the early 18th century in Europe. This type of necklace was often presented as a choker that had a continuous line of gemstones that were graduated in size. Sometimes they would be equal in size as well, but typically there was a pattern of sorts presented in the necklace. The single row of precious stones may also be surrounded by other precious or semi-precious stones. These necklaces are still worn at times, but are most commonly found in antique jewelry dating back to the early 18th century from France and England.
