hi Barbra!
I really enjoyed Justin’s dialogue with Rex Guo. Justin is a natural interviewer, that goes without saying. Within the topic of gem faceting, Rex described a variety of interesting science truths that one learns only through deep study.
and for more info about Rex, check out his SutraGems facebook page. He posts a lot of really informational stuff about cutting fine materials and really considering color, light performance and weight
