British Gold Hallmarks and Gemology Report by: Yvonne Hammouda-Eyre
Hi Mrs E - glad to see you're using a jewelers loupe! Yes, the RJ will be the maker's mark.
The crown followed by 375 is the purity mark. If there is a decimal point before the 375 it means the ring was made before 1975. Have another look under the jewelers loupe magnification for the decimal point. It means its an antique gold ring.
The sovereign's head was struck to show that the duties had been paid. It could be the duty mark (Excise Duty) or it could be a commemorative mark that commemorates a special event like the Coronation of Queen Elizabeth II in 1953, or Queen Mary in 1935.
The D or B is the date mark.
If you want t to sell the ring, for your own peace of mind and also the buyers, you should have the ring appraised. There is a special way to calculate the weight of the diamonds when the stones are already set into the jewelry. Also a gem report will tell you the quality of the ruby. Some rubies, depending on a number of factors, including its size, can be more valuable than diamonds. Have it appraised, I would not recommend an on-line appraisal service. The stones need to be tested.
