04 October 2022: -

Shipping service from Thailand has resumed, we will be using Thaipost.

All paid order will be ship within one week.

- Due to continuous weekly auctions at e-rocks, we  need to prepare many packages with care and complete information , sometime rarely paid orders get delays up to maximum one week because of my unexpected mineral trips to mining areas, or late cargo for moving  minerals to  our shipping base at Thailand, my apologies always for the inconvenience. 

2- Flat shipping charges to world wide , we combine orders to reduce overall shipping       cost, Please find your tracking number from your shipped order page

I am always thankful to all of my minerals friends for their long time support and understanding.

Cheers.
