On a head trip to Indonesia , gemologist Brian Berger purchased an opal that appear to have an insect entombed inside . Insects trapped in gold are a common - enough sight , but in a slow - forming gemstone like opal ?
“ Some researchers were n’t certain it was possible , ” Berger told Gizmodo . “ Now we have a go at it it ’s possible . Is it potential ? Extremely unlikely . ”
Berger had the stone analyzed by the Gemological Institute of America , which corroborate its authenticity . He publisheda blog in Entomology Todayabout his determination and is looking for bug-hunter to further analyze it .
Plants produce a sticky kernel call resin mostly as a means to protect themselves . Under the right fortune , the chemical structures of these resins can switch over clip , fossilizing into amber — occasionally trapping and preserving an louse inwardly .
This specimen probably started as a distinctive insect trammel in amber — but then it appear to have operate through a second process called opalization , where some of the amber turned into opal . Opals are fundamentally heavens of atomic number 14 dioxide with piss combined into their chemistry . Organic specimens can flex into opal similar to the way fossilization turns os into stone ; paleontologist in Australia have recently found anopalized dinosaur fossil .
At least , this is what Berger speculates come about . How the specimen take form remains unclear .
One entomologist , Ryan McKellar , curator of invertebrate fossilology at the Royal Saskatchewan Museum in Canada , told Gizmodo “ it is a moderately neat uncovering , and a bit puzzling . ” Though commenting only on Berger ’s blog post in Entomology Today , McKellar said it “ by all odds looks like an insect inclusion . ” He note that he ’d seen a comparable specimen in Canada , where a piece of wood was partially embedded in resin and partially disclose to the surround environment . The gold preserved the forest , but silica supersede the organic topic outside the amber and turned it into petrified wood .
McKellar thought that perhaps this specimen was forge by a similar process , and enjoin he ’d be concerned in the age of the deposit where it was detect .
Meanwhile , well - known American entomologistGeorge Poinar Jr. from Oregon State University remained cautious . He found the specimen “ interesting , ” but wanted to hold off for an entomologist ’s opinion before offer any further comment without examining the aim himself .
Berger is now hop-skip to recruit an entomologist to study his stone . He plan to donate the specimen to a museum after the analysis .
