Black Knight jewellery be careful ! Dishonest !

The company sells stones that are not the weight advertised. The rating / quality of the stone is much poorer than advertised ! Please check Bid or Buy reviews. The person in charge Cathy is dishonest and refuses to contact customers if she gets questioned ! The componay is dishonest ! I'm currently in the process of claiming R8000 back via my bank as Cathy will not respond to any emails or correspondence, not even with the bank! Certification issued with the stones are not by a recognised authority !!! do not do business with this jeweller! They trade from home so you can't even view the ring or gemstone until the transaction is complete !!!!
