I purchased a Aquaprase ring, it arrived cracked, I sent it back at a cost of £7.45 they sent me another one that was a size R I am a N. I saw that LeVian were doing a ooen day at my local mall so I brought the ring in the representative for LeVian did not believe it was a Aquaprase so I said I would bring in a authenticity certificate when I returned they were and I was shocked as they said that stone did not represent what they were selling. I asked the jeweller how much they thought the ring was worth and they stated the price of the silver. I was lead to believe that this stone was worth something and a investment even though the female presenter said shes "not really able to say that" she did..What I am stuck with is a worthless rock that sits in the drawer
