It means that it was worn by the queen......
18 karat
That sounds like a hallmark stamp telling who made it.
The crown is a standard mark, meaning the gold conforms to one of the gold standards. K stands for carat. It is a unit for purity of gold. 22K indicates that the ring is 91.7% gold and 8.3% other metals.
i have a gold ring with ING stamped on the inside , what does that mean ?
it means it is 16 carat gold ring
gold 335
What does SC mean inside a.ring
owned by royal in past life
sterlized
An S inside a gold ring is the maker's stamp. If the ring were not gold and had an S inside it would stand for sterling silver.
Gold Plated
If this is the first two letters of the Hallmark these identifie the 'Maker'. SH i believe is Samuel Hill. That will be followed by the 'Crown' of british recognition. Then the Carat 750... is 18ct or 750 parts gold per 1000 ie. 75% pure gold. The final letter is the date letter... Of which there are many.
