I do not take orders for custom work. However, if you would like a to request a modification let me know and I will see if I can make one with the modification you would like.
All work is guaranteed for quality workmanship unless abuse has caused an issue. Remember, cloisonne is glass on metal and although it is not terribly fragile if it crashes down on a hard tile floor it can crack or chip. Treat your pieces as you would any fine jewelry.
