Tiffany Setting refers to a ring setting named for the jeweler Tiffany & Co. that began using the setting in 1886. Tiffany Setting is characterized by a high five (5) or six (6) pron g setting that rises up away from the shank to secure and protect the stone. There are variations on the setting, but traditionally, the prongs are slender and the presentation is simple.

Tiffany Setting is normally a rounded 6 pronged setting with thin prongs which flare out from the base. Introduced by Tiffany and Co. in 1886. Often used for large diamond solitaires today. It is also sometimes used to describe a four-prong setting.
