TWO-TONE GOLD: Gold is a precious metal which is often alloyed with other metals to increase strength and create different colors. A two-tone gold piece includes two colors of gold: yellow, rose, white, or gunmetal-finished gold. The purity of the metal is indicated by a unit called a "karat," with 24kt having the highest percentage of natural gold.
POLISHED: A buffed-out finish used to produce a mirror-like shine.
ROLO: A chain comprised of interlocking circle-links.
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.
