tanzanite Ring and earrings

Tanzanite sterling silver ring
Beautiful blue purple tanzanite cluster I''ve included similar color earrings I believe they are silver but not sure what the stone is, they are really pretty tho. I will update the pictures because this one''s aren''t the best. They do no justice.
Thanks for looking♡♡♡
