Amulets are usually reasonably finished between six to nine months, so Arden's first crystal likely would have been completed somewhere between March 2017 and June 2017. He would have needed to get at least one or two other amulets up to this point!

Let us know if you'd like to submit any further crystal completions from that time and what month you'd like to mark this one down as so we can put it in the spreadsheet!
