Can someone educate me on sunstone? It seems out of the mainstream of jewels and yet I have seen some that look almost identical in color to rubies. What makes sunstone so much less expensive? Yet, I have seen prices around $300/ct for a Tibet mined sunstone of brilliant red color. I admit...I am new to the gem world, yet drawn to it''s beauty. I don''t want to get ripped off on pricing. Any info appreciated.
