Third one I purchased and happy with all
This one is the reversible sapphire/ruby and both stones show and sparkle in the light nicely.  The Ruby is more vibrant than the sapphire, but both are very nice.  I usually wear an 7.5 - 8 but ordered 7.5 feeling the band was relatively thin.  It fits nicely on either ring finger and had I got an 8 it would have worked on pointer finger or middle finger, but then would have been loose on the ring finger.  It appears sturdy, a nice antique looking gold (not shiny) & good craftmanship.  I recommend the ring & seller.
