Bespoke pendant

I decided to add the bespoke product to my website. This what I want to offer is an decorative initial letter pendant. It would be a fantastic birthday gift to girlfriend, wife, daughter or granddaughter with the first letter of her name and birth stone added to the pendant. In standard version I can offer Swarovsky crystals with colour of the birth stone. The real gemstone could be also used but some of them are more expensive than the others so additional cost needs to be calculated. The braid is made from fine 28 gauge (0.3mm) wire. Material could be copper, silver filled, sterling silver or gold filled.

The pendant is approx. 30 mm diameter and it comes with 20" chain of matching material.

What do you think about the idea?
