Wonderful Roman glass 2000 years ago mystery

I am looking at the roman glass that I won at an overseas auction.

I enjoy this beauty and the iridescent change that nature woven into the Mediterranean soil buried in glass created by mankind about 2000 years ago.

It's an amazing art created by humanity and the earth together.

Unfortunately, it is not excavated in Japan, but many countries in the Mediterranean coast have been excavated in the Middle East and exported overseas as jewelry.

It is also famous as a souvenir from Israel.

In Thailand, fragments of this roman glass are sold and purchased by domestic contractors.

At department stores, they are processed as jewelry and sold as pendant tops and brooches at high prices.
