I and my friend made a diamond ring buying trip to London because we are worth it. We started our diamond tour from QD/Paul. Nice & professional, not pushy service was provided. Paul searched not the lowest price but the best looking (excellent cut&polish, eye clean etc.) reasonable priced diamonds for me, all in US. An ad hoc appointment in next day was arranged exactly when I wanted. A diamond was delivered from US, was set in Hatton Garden, paid with international bank transfer and delivered via FedEx. This all within 2 wks. Amazing. SHE, my diamond ring, is perfect! When visiting the local diamond stores the offering there is nothing (size, sparkling, fire) compared to my ring. The price for smaller and lower quality diamond is at least 2*higher. Definitely recommended. Next time when I am worth it I will revisit QD.
