Wow!!! that is exquisite ! THe stones look of a particulary high quality based on my impression of their translucency? Please don't tell me they are pastes!!
Can you give us some details on the stones, the large light blue one looks like topaz, I assume that some of the others are lower grade (jewellery wise) sapphires and rubys??
Forgive my ignorance , but are the processes for gilding plateing of the gold?
