Two small gold rings have opened a window onto a 2,000-year-old burial in western Thailand.

The rings were found in late June at the Don Yai Thong archaeological site in Phetchaburi Province, according to The Associated Press. Thailand’s Fine Arts Department said the rings were buried alongside human bones.

Don Yai Thong is about 80 miles southwest of Bangkok and was only recently identified as an archaeological site. Residents found fragments of ancient bronze drums in a rice field earlier this year, prompting archaeologists to excavate the site.

One ring carries a short inscription etched into its oval face. Experts believe it is written in the ancient Indian Brahmi script and reads “pusarakhitasa,” meaning “the one protected by Pushya.”

Pushya is a lunar constellation in ancient Indian astronomy long associated with good fortune and protection, suggesting the inscription may have been intended as a blessing.

The second gold ring is also well preserved but has no pattern.

Experts believe the rings’ owner may have belonged to the Vaishya class, traditionally associated with merchants and traders in ancient India’s caste system.

The rings are among a host of finds at the site, including eight human skeletons, bronze and gold jewelry, pottery and other artifacts. The grave goods suggest the dead were members of society’s upper class.

Officials said research at the site will continue, and the excavation is expected to wrap up sometime in July. The artifacts will eventually be put on public display, the AP reported.

The find follows other recent excavations involving ancient gold treasures. In February, Panamanian officials announced archaeologists had unearthed a tomb more than 1,000 years old filled with gold artifacts, finely crafted ceramics and other funerary offerings at the El Caño archaeological site.

In May, Egyptian archaeologists uncovered a cache of ancient artifacts at the biblical city of Heliopolis, also known as On.
