Client Testimonials
Annette at Australian Pink Diamond Investments was immensely helpful to me as a novice investor in Pink diamonds from the Argyle mine, in finding just the right ones to suit my taste, my budget and my risk tolerance.
Australian Pink Diamond Investments were able to put literally hundreds of stones in front of us from their vault, where the others had maybe 3 or 4 to offer. We were very specific in our size, shape and colour requirements, and selected maybe 8 stones from that narrow range then lined them up on the table in front of us to make our final choice. No one else could offer us that range, immediacy and specificity
Annette and Craig have gone above and beyond to ensure we had the opportunity to purchase some truly unique investments. The level of expertise, professionalism and communication demonstrated have been outstanding
