DIAMOND

A diamond is the oldest item that anyone can own - it's three billion years in age, a strategic and high tech super material for our technological society that is formed in the earth's interior and shot to the surface by extraordinary volcanoes.

GOLD

Pure gold is too soft to withstand the stresses of every-day wear, so it is alloyed with a mixture of metals like silver, copper, nickel, and zinc to give it strength and durability.

PLATINUM

The most appealing characteristic of platinum is its durability. Each time other metals are scratched or polished, a tiny bit of metal is lost. In fact eventually, prongs of white gold and yellow gold may wear down enough that you need to have them reinforced with more metal for safety.

Pure silver, also called fine silver, is relatively soft, very malleable, and easily damaged so it isonly combined with other metals to produce a more durable product.
