I purchased a Diamond Engagement Ring from Vashi.com online and paid the full amount of £2,464.05 on 10th July 2015. I proposed to my partner with the diamond ring on a holiday to Barcelona. I went to great expense to get everything right,*which was very important to me. We stayed at a 5 Star hotel in Barcelona, I hired a table on a secluded veranda overlooking Barcelona, hired a Mariachi band who were playing a serenade where I proposed with the ring I had purchased from Vashi.com. Everything went and seemed perfect. On our return from Barcelona we asked Vashi.com to alter the size of the ring as it was too big and to upgrade to a different stting design, which we chose in person at the company’s London shop and paid a further £301. I received the amended ring at my home by registered post on 12th August 2015 and signed for it. The Engagement ring was given away to my fiancée as a gift at the blessing ceremony on the next day 13th August 2015. Vashi.com telephoned me on 18th August (7 days after I received the ring) checking if I have received the ring because their system showed that the ring is still in the depo and during their stock check they suspected an error. Upon my confirmation of receipt of the ring Vashi.com expressed the suspicion that I may have received an incorrect item and asked me to send our Engagement ring back. To cut a long story short we refuted their claims believing we had our ring we paid for. They then accused us of retaining a ring that did not belong to us saying that another customer wanted their ring back, giving us an ultimatum to return the ring or pay an additional £1000. Also the so called diamond certificate is not a certificate (has no number on the diamond) and is indeed their own appraisal. They have harassed my fiancee and I since and now have issued a claim in court against us! Any advice? surely this must be a breach of our consumer rights. We are in court on the 16th March 2016.
