""Living in Central Queensland without easy access to high end jewellers, I reached out to Dave at Bullion Diamond Co. in WA for the purchase of a quality one-of-a-kind natural diamond engagement ring Dealing remotely with someone I hadn't met face-to-face, Dave took the time to put me at ease, sharing his extensive knowledge of diamonds and ring designs over many exchanges. Numerous photos and drawing ideas were provided and tweaked until we had the perfect stunning engagement ring design. Dave then sourced just the right natural diamonds to match my specifications and worked with his master goldsmiths to create the real thing. Dave's outstanding customer service extended to all the appropriate valuations, certificates, assistance with relevant insurance, and postage to Central Queensland, where I have now received our creation. I highly recommend BDC and will definitely be a repeat customer, especially once my future fiancé sees her ring!""
