Gold is never old. Vintage and Antique gold jewelry is not referred to as used or second hand as one might refer to a 20-year-old car. Gold is infinitely recyclable, the gold that one has on his or her finger now maybe from melted gold once worn by Cleopatra or King Solomon. All Gold is ancient in the extreme. Gold is created due to a process called supernova nucleosynthesis, which occurs only inside of an exploding star. The astronomical heat and pressures generated inside of a supernova is the only way gold is created. The gold on your finger is not millions of years old, but billions. The unique properties of gold is what makes it so desirable. Gold does not oxidize or tarnish, and is resistant to almost any acid short of aqua regia (nitro-hydrochloric acid) so named because it is one of the very few things that can dissolve gold.
