Ianto would like to buy a birthday present for his girlfriend boss, and we'd like to check the price.

He wants to buy a silver glass locket containing a carefully curated collection of small (think smaller than pinky nail sized) gemstones and semi-precious stones (example image here, but with a few little period touches in the metalwork)--fourteen stones total.

What might a local jewelrymaker ask for such a bauble? >.>
