Amber is fossilized tree resin (not sap), which has been appreciated for its color and natural beauty since Neolithic times. Much valued from antiquity to the present as a gemstone, amber is made into a variety of decorative objects. The abnormal development of resin in living trees (succinosis) can result in the formation of amber. Inclusions of other substances can cause amber to have an unexpected color. Pyrites may give a bluish color. Bony amber owes its cloudy opacity to numerous tiny bubbles inside the resin.
Gold(14K) A coating of gold is deposited on the item using the galvanic method or IP process. It is mixed with other metals, usually silver or copper, to make it less expensive, harder, and longer lasting while preserving the brilliance of pure gold. 14k gold is 14/24 of pure gold, which is approximately 58.3% pure gold.
