Purchase of 1 1/2 carat solitaire

Bought a beautiful 1 1/2 carat solitaire engagement ring for my fianc just before Xmas. She absolutely loved it. The diamond is stunning, and clear. Heidi was extremely helpful and went out of her way to sort everything out for us during the purchase, from choosing the right diamond right through the process up to delivery.

Beautiful 1 carat diamond ring

Lovely ring, beautiful setting, unaware of the £182 import tax that I had to pay but otherwise a lovely purchase.

Gareth Foster
Engagement ring

Brilliant service from start to finish. I was recommended by friends and to be honest was a bit worried at first about ordering online without seeing the product in person. However the service I had soon made me realise I had made the right decision. Communication was top class and all my questions were answered more or less straight away.
Thanks for all your hard work. Hopefully be back for the wedding ring soon.
