SETTING
Name

Definition
Pave Setting
• Gems are separated and held in place by
little beads of the setting metal
• Looks like a continuous surface of gems
Prong Setting
• Gem is inserted into three or more metal
prongs
• Gem sticks up way above the finger
Channel Setting
• The gemstones flow in a continuous row,
because no metal is used to separate
them
Micro Setting
• Simply pave setting, but on a much
smaller scale
• Gems very close to each other
