ROSE GOLD: Gold is a precious metal which is naturally quite soft. To give it a rose color and increase its strength, gold is alloyed with other metals, such as copper and silver. The purity of the metal is indicated by a unit called a "karat," with 24kt having the highest percentage of natural gold.

ROPE: Chain links that are twisted or looped together in a pattern that creates a look similar to that of a rope.

SPRINGRING CLASP: Invented in the early 1900s this diminutive device is highly effective. It's a hollow circular metal fastener with a spring opening. This keeps the clasp closed.
