Why is jewelry rarely made from 21 karat gold?
21 karat gold is still to malleable or too soft to make a practical piece of jewelry as it will bend or break easily. Most necklaces are made of 14k and most rings are made from 10k. Even at 10k, rings still will wear down to the point of breaking on the palm side of the hand.
Is white gold a compound or mixture?
The term 'white gold' is used for the element Platinum. Best AnswerAsker's Choiceskipper answered 5 years agoMost alloying metals to gold will tend to whiten the color and so it is possible to make carat golds that are white in color.

There is no legal definition of what constitutes a white color in golds. Many commercial white golds are not a good white colour and are sometimes plated with rhodium to obtain a "white" color.At the 9 carat (37.5% gold) level, a gold-silver alloy is quite white, ductile although soft and is used for jewellery purposes.Nickel- and palladium-free 14-karat white gold alloy composition can consists of the parts by weight: about 58.34% gold, about 35-40% silver, about 0.5-1.80% tin, and about 0-0.75% germanium.18-karat white gold alloy compositions are often 75% gold and 25% platinum or pallidium or 75% gold, 10% palladium, 10% nickel, and 5% zinc.

What does 725 stamped on a gold 1865 pocket watch mean?
It means that the gold components of that pocket watch are made of 18 karat gold. The max is 24 karat gold (pure gold). Most high end jewelry are made of 18 karat and very rarely 21 karat. There are no 24 karat as they would be at high risk since pure gold is very malleable (can bend easy). Since 18 karat and 21 karat are not 100% pure they are mixed with usually copper for yellow gold or silver if you have white gold.
