Phloi Waen

Phloi Waen (Thai: พลอยแหวน, pronounced [pʰlɔ̄ːj wɛːn˩˩˦]) is a tambon (subdistrict) of Tha Mai district, Chanthaburi province.

It was named after a hill with a Buddhist temple on top, Khao Phloi Waen.

According to the survey, lots of rubies and sapphires were found around the hill's area.

That was where the famous rubies of Chanthaburi started, and continues to the present.
