Antique Georgian Silver & Black Dot Paste #ERAconversion Charm

We are so loving these seriously edgy antique Georgian silver and black dot paste charms! 
We re-designed them from an antique pin, which has been tested, and added 9 carat gold bales to them. We started with 10 and there are now 6 of these beauties still available, some with yellow and some with rose gold bales, so please ask for your favourite combination, as there is a choice! The charm on the second row, far right has now sold fyi..
The cut of the paste is most unique and we couldn't quite decide whether they are Georgian hearts for love... shields for protection... or we even thought ... a shark tooth for strength perhaps?? What do you think? 
They on average measure 7.7mm North to South and 7.4 mm across at the widest. The total length of the charm id 13.7 mm and they weigh about 0.8 grams each. In very good antique condition too!
