Antique Silver Inlaided Tea set

I brought this gorgeous tea set in store in Japan. The item has a solid silver inlay and I haven’t seen anything like it around (including on the internet). NOT SILVER PLATED!

while i’m not particularly sure of its origin, it doesn’t have a stamp on the tea set other then a stamp silver of a city in China made in silver on the pot’s handle. The item itself is handmade including the decoration of silver (as they aren’t aren’t perfectly identically around the whole item).

I’m curious on how much it might be worth.
