It probably means the jewelry is electro-plated with 14 karat gold, not solid gold.
Electroplated
Ep generally means Electro-plated, meaning the piece is plated. Likely the actual mark will be "GEP" Cheers.
585 is the same as 14 kt (karat) gold. It means it has 58.5% gold. EP probably means electroplate although there is a old jewelry makers mark/stamp "EP" too. (See last source for pic of old mark)
The EP means Extended play. So it is longer
I am quite certain it means "electroplate", so I presume if an item is sold as 925 sterling silver ep it implies that it is silver electroplated over another metal. I would like to know if this is an accurate assumption and what is the metal the silver is electroplated over?
It means that there are a high quantity pf these cells called ep in your urine :)
EP, sometimes in movies means 'Electromagnetic Pulse' , again depending on the context.
The EP on Gorham silver means "electro plating". It is not a sterling silver piece.
what does cor means in jewelry
Electro-plated nickel silver
EP means extended play, which is like a demo, but a little longer. Hope this answered your question :^)
831 on jewelry means love you
Probably not a silver piece, EP usually denotes Electro plate London, GS probably the maker.
