The setting is a cool story. It was originally made, as a ring, for a very expensive lab Pink Diamond. Years ago. We ended up re-setting the pink diamond for it's buyer, at that time. The setting, made by our "Uber" shop was preserved. THis particular diamond fits perfectly. We used a 16inch, Italian Platinum chain. Lovely piece. The stone is set E-W, which should be great for the pendant. More details about the center stone I do love emerald cuts - which shows in how many we've put on the site. The super well cut emeralds we pick look so durn nice in Blue. Small table - generous crown makes this stone so lively
