  • Wow what service - bought an engagement ring from Pravins and the service was exceptional from start to finish - Janeal was superb and went above and beyond to make the experience easy and enjoyable. Her knowledge, experience and advice helped me no end and she was a pleasure to deal with… Exceptional customer experience at its best. Thank you so much and would have left 10 stars if I could have - recommended service, staff, and ring too!

  • I had a virtual appointment this afternoon with Pravins to look at some necklaces and it was a brilliant experience. They called ahead of the scheduled time to confirm i could still make the call, sent pictures of the products I was looking to review and then we jumped on a zoom to discuss further. Very attentive and great way to engage with customers during this period of restrictions.

  • The jewellery itself is all stunning and we have been so pleased with the quality, the care, the service and after-service received. We will certainly continue to buy with Pravins going forward and we highly recommend it to anyone looking for stunning jewellery and fantastic service.

  • Would highly recommend Pravins, we received excellent customer service from everyone in store. We purchased an engagement ring and our weddings rings with Jared, who was welcoming, helpful and knowledgable, giving us great advice throughout.

  • Would highly recommend Pravins especially if you are not the most confident person when it comes to picking jewellery. Thankfully my partner and I were greeted by Stephanie who then took great care of us from start to finish. Complimentary drinks were offered straight away and she took her time going through every detail making sure we were happy and that it was not just about the sale for her. She literally went above and beyond for us, making our experience enjoyable and comfortable. She and her colleagues were amazing and very welcoming, could not fault anything about the company.

  • Professional, Personal, Perfect. From the moment we walked into the store we were made to feel welcome and we knew we were in expert hands. The Cardiff store is spotlessly kept and every staff member, always immaculately presented, went out of their way to make us feel relaxed. It took us a number of visits to find the perfect engagement ring but each time we visited the store we were treated with patience and total professionalism by a knowledgeable and genuinely caring team.  An enormous heartfelt thank you to Janeal, Steph and the whole team for making it the most perfect experience on our journey.
