What is it? I've found descriptions of it as 18k, 22k, 18.5k, some mention silver alloyed w/gold, others say it's the same as green gold. What is the alloy?
I've never heard of it before seeing this listing in the Sotheby's Geneva auction tomorrow:
So have I, but the Sotheby's listing doesn't mention gilding. Even if it is mostly used that way, I want to know what it consists of. It's a term I haven't ever heard before. Anybody?
Karat - 24 karat gold is pure gold with no other metal added. 12 karat gold is 50% gold and 50% other metal. The karat weight of gold leaf ranges from 12 karat white gold to 24 karat, 22 & 23 karat being the most popular for leafing.
Color - The metals mixed with gold in its making change the color of the gold produced. There can be different colors of gold within the same karat. 23kt gold can be a Red Gold, a Rosenoble or a Duketen. Lemon gold was generally a term for gold that was not red. Today it can indicate an 18 karat gold instead of 24 karat gold.
