Hi Lue. Thanks! Have been very curious on how well GemVal tracks with other resources. Been wanting to compare notes with others on its accuracy, so I hope Jonathon’s appraisal can shine some light on the question. 
I am impressed on how GemVal keeps track of a collection and updates the valuation based on current industry info. Just not confident in the price points, since very few scoring criteria is used to provide a value.
Jonathon (@JonathanK94858 ) must apologize up front for volunteering you to be a subject in my impromptu science experiment… 
Looking for other “volunteers” as well. 
I do have a few out for appraisal, so I will post my notes when they are complete.
Cheers!
