Hi,
I have such experience. You offer replacement. That is the best option in my opinion. If that stone is emerald or sapphire, it will be problem. Because emeralds come with chromium inclusions. Without tiny black specs, emerald is just green beryl. If it is transparent ceylonese sapphire, it will show inclusions very clearly.
In one instance I replaced one champagne topaz with other stones.That worked just right. In another instance I had to send four emeralds for replacing one. It also worked somewhat.I dont want to say anything against my buyer. I think you understand.
But ,go on contacting buyer. Just keep cool.
It will be sorted out. Yes,no problem is problem really.
Thanx,
Truly,
Amitava
