#jewelleryfacts365 282/365 Gold fact

Solid gold jewelry does tarnish. However, pure 24K gold is not susceptible to tarnishing. The other alloys like copper and silver used solid gold jewelry cause the tarnishing. The higher karat the gold is, the less noticeable the tarnish will appear over time. This explains why a lot of antique gold jewelry from the Victorian era has a dark rosey tone to it. The lower karat jewelry of this time period used a lot of copper which creates a beautiful patina that cannot be replicated. Cleaning of antique jewellery will reduce their value..

The visors of astronauts' space helmets receive a coating of gold so thin (0.00005 millimeters, or 0.000002 inches) that it is partially transparent. The astronauts can see through it, but even this thin layer reduces glare and heat from sunlight.

Benitoites of excellent gem quality and transparency rarely exceed two carats, and few that do have such good color saturation combined with the gemminess. Most stones tend to have one or the other. This is an impressive brilliant oval that is very bright and has good clarity as well. It is big and impressive. Rough-and-cut sets make fabulous displays and this would fit into such a set, or it is of a hardness that makes it also perfectly wearable for jewelry. A classic rarity that will be difficult to replace as the deposit is unique in the world, and is now more or less stripmined and depleted. From the collection of former mine owner Bill Forrest. There have been quotes on pieces of this quality and size at $10,000 per carat retail.
