9.25 is a mark used for silver. 9.25 meaning 92.5% silver is the minimum standard for something to be classified as sterling silver. You must be confused and think you have a piece of white gold when in fact it is silver.
925 means 22kt gold or 18 kt gold
No, sometimes there is also 24 kt gold.
rgp 10 kt means its "rolled gold plated" of the 10 kt variety
Pure gold is 24 kt. 14 kt gold is (14/24)=.5833 pure. Multiply by 100 and it is 58.33% pure.
24 karat gold is 100% pure gold. There is no such thing as 28 karat gold.
23.65 Kt, that be a lot of karrots.
10 kt gold is lighter yellow than 14 kt gold
Probably not. The HGE mark is an indication of "heavy gold electroplate." This means that the ring is made of some metal over which a layer of gold is plated.
There is no such thing. The number is wrong and the word is spelled with a "k". If you mean .958 (point nine five eight), that is the specific value of what is called 10 karat, or 10-kt gold. Pure gold is 24-kt. gold. 50% pure gold is 12-kt. Therefore, 10-kt gold is only 41.7% pure.
US $20 gold coins are made of 90% gold, which puts it at about 21 1/2 kt.
Your ring was probably made in England or another country that doesn't use our standards. In USA we mark items with KT such as 18KT. Your ring is probably 22KT gold. it is gold plated sterling silver In the UK we do not use 925 on gold or silver. We use a 'Hallmark' that is for every area of the UK from which it was made. This is helpful when 'pricing' antiques as the hallmark identifies the area, manufacturer and era from which it originated.
It means that is it 18 kt gold. XXX = .750 or 18 kt. Hope that helps.
