Hi Haley thank you for writing in with the following hallmark questions:
"i have a gold ring which has a well what i assume is a pharoh's head and the hallmarks read: crown, 375, leapord head, and a x on the other side its marked g.g what does this mean and how can you find out about prices."
Based on your description the marks might be pseudo British Hallmarks on Egyptian revival jewelry that typically featured traditional Egyptian symbols such as scarabs, ankhs, sphinx, pyramids, and pharaohs. When King Tutankhamun's tomb was discovered in the 1920s, it was not only an important archeological find, it influenced everything from architecture to fashion. This period became known as the Egyptian revival. Vintage fashion fans should note that there were two important Egyptian revival periods in fashion. The first took place in the 1920s and the second took place in the mid 1970s.
Egyptian revival jewelry and accessories became very popular with women in the 1920s. Women wore snake bracelets on their upper arms or beaded headdresses like Egyptian revival jewelry often was made with precious metals such as sterling silver or gold. Egyptian revival accessories from the 1920's are significantly more expensive than their 1970's counterparts since they were made with better materials.
British Hallmarks, a crown is followed by 18 or crown followed by 22. Another puzzle is the X - the X letter was used on imported wares. (the shape of the cartouche behind the X determines the metal composition, ie silver, gold, platinum. Either pseudo-British marks or made in foreign country for UK Import.
The description of the maker's marks and date letter is too vague.
