Pink Diamond Argyle Certification Explained

At Waldemar Jewellers, our proficiency in determining the quality of pink diamonds is one of the reasons we have earned the reputation of Sydney’s best jeweller.

The most expensive Pink Diamonds are the ones that come with an Argyle Mined Diamond Certification.

Each Argyle Certified Pink Diamond over eight points (0.08ct) since December 2016 is laser inscribed with a unique lot number that is only visible under a microscope. These numbers correlate to the Argyle Gem Identification and Authenticity Document, this guarantees the chain of custody from the Argyle mine to a trusted trade partner. Between 2009 – 2016 all Pink diamonds above 0.15ct were inscribed with a lot number and prior to this between 2004-2009 all Pink Diamonds over 0.20 cts have the inscription.

Colour Intensity and Carat Weight are the biggest factors influencing the price of your Pink Diamond.

My partner loves her engagement ring from Waldemar. Mark took the time to really listen to the story of our relationship and help craft a beautiful ring which my partner adores. He was also very helpful with arranging for a resizing. I highly recommend Waldemar and Mark for anyone looking to purchase an engagement ring or diamond – every detail is so thoroughly thought through and tailored to your relationship and requirements.

Mark was very helpful throughout the entire process especially when we needed to resize our ring! His explanations about diamonds were informative and his craftsmanship was amazing for a very affordable price. 100% would recommend. My fiance is in love with her ring.

Thank you for designing such an elegant and beautiful ring for my wife. She absolutely loves it! It was great to work with someone like yourself and receive the personal 1:1 attention when we were making a decision on something so dear to us and we are both very happy with the outcome. We walked into your store by accident, but we are both really glad that we did! We had a great experience working with you and would definitely recommend you to others in the future.
