Looking for any information on this necklace

Seem to think it is from about 1870 - 1905.

Could anybody tell me the name of woman on the necklace.

Thanks

Have found out that it might be by Lawrence Alma-Tadema

Could I have a valuation as well. It has a 925 silver stamp on the back.

Thanks

I am sorry to disapoint you, but what you have looks like a copy of a victorian porcelaine plaque. The 925 indicates it is silver but Continental

If the item was English it would have HALL MARKS and from that you can tell the City and the date it was manufactured

Items like this are quite common in antique fairs they sell from £20 to £50.

If it had been made in the late 1800 insurance value would be at least £500

Also if the Lady was a famous person this also would add to the price.

All the best
John
