✅ SOLVED Opal?

[HAPPYCAMPER]

Found today at a site dating back to 1700s,we didnt find any modern debris or items.House still there being renovated at this time...gent who owns very generous on letting people detect this house and seemed fairly picked clean.A couple tombac buttons and a half cent found.Just looking for input on whether this is an opal.

only a jeweler can tell you for sure....it could easily be glass, but what is an opal?....amorphous silica...what is glass, a silica based solid
