The agate was recovered from the Rio Grande do Sul region of Brazil by gemologist Lucas Fassari in November 2020.

A geologist in California says he’s received multiple offers of $10,000 for the rare rock, which was recently discovered in Rio Grande do Sul.

Owner Mike Bowers said he’s been inundated with interest after showing off the volcanic rock on Facebook earlier this month, as the interior blue quartz crystals and smile-like void look just like the hungry monster.

“It is somewhat uncommon to find a face shape in agates,” he explained, adding that the gemstone is even rarer because the face is a mirror image on both sides of the sliced stone.

According to the outlet, agates, a type of quartz, are formed within cavities of volcanic rocks. Their colors come from chemical impurities in silicon dioxide and how crystals are spaced.

The collector acquired the agate from a Brazilian gemologist, Lucas Fassari in November, who picked it up in Soledade, a hotspot for precious stones.
