My lovely Amethist collection

I adore the purper color of Amethysts especially in combination with the gold. Here I show my favourite pieces mostly combined with seed pearls.
The oval brooch has no hallmark but tested for 14K and Etruskan style. The round brooch has a hallmark which I cannot decode but tested also 14K. The wonderful large Amethysts of the earrings are marvalous in my opinion. Tested also for 14K. I suppose all these jewels date the end 19th century. Do you agree?
