13.7 gram 10kt gold chain
yes
It means it's 10k gold... 41.7% Gold... Hope this helps...
If I read your question correctly the bracelet is made from Italian lire coins and the chain is 10K. If these are real Lire the coins they are not gold, but that they could be set in a 10K coin holder to hold them to the chain. Often when coins are used in jewelry they are placed inside a frame/holder. My guess is that what you have.
21,000
Yes , It means it is 41.7% pure or 10k
What is F9 stamp
It is most likely a "Makers-mark". It is a mark put on the chain to show who made the piece of jewelry. It will have a 10k 14k or 18k beside it if it is gold.
My ring happens to say this, and I assume it indicates it was produced by ASK Gold Co. in Los Angeles. Their website claims they are "the leader in 10K Gold jewelry for 25 years." "" 10k means it is made out of 10 karat gold and it depends on the condition it is in that the pricing is good.""
This means 10k gold.
