Antique Exquizite Red Stone & Gold Colour Broach

Wow this is an Exquizite broach that has a gold colour which wouldnt surprise me by how old this broach looks and by the cut of the ruby red colour red stones. Im not sure what stones these are but there are 2 small stains on the back that show people have tested for it to be gold or not but i am unsure of what it is... i couldntest it again but i dont want to ruine this beautiful work that someone in the past has put days into making and cutting these stones to shine and polish. So thus as i dont know if it is gold or not i can not mark it at a gold price but this item still is an antique and is quite old so this item is priced just right... Just above cheap lol.The length is : 7cm. There are over 50 of these red stones and this broach weighs : 8.5 Grams.
