Large Statement Silver/Rhodium Cross

Gorgeous Statement Cross purchased from a jewelry boutique on the Island of Santorini, Greece. Setting is Sterling Silver Rhodium with pale pink stones in cushion cut at all 4 points, and middle of the Cross is blended with pink and white round stones. They may be sapphires or Crystal quartz and sparkle beautifully but not like cubic zirconia. When using my presidium gem tester they were hard to identify. The white stones jumped to Diamond but not the pink. So in summary I’m not sure of what the stones are but it’s a magnificent statement piece and will not tarnish.
