Is this a Pure Heart Crystal?

Character Group shot 15 of 20. Sailor Neptune & Sailor Uranus Take 1. During the Youmacon 2013 Official Sailor Moon series con photoshoot they had the Outer Sailor Senshi pose for a couple of photos. Marie made a large realistic Heart Crystal prop which both she and her Mother are holding. During the Sailor Moon S season Sailor Uranus often asked Sailor Neptune if the Heart Crystal that they had just collected was a Pure one.
