Australian clients can now order Fairtrade Gold

Fairtrade Gold is now available for all clients in Australia. If you are interested in commissioning your engagement ring or item of jewellery in Fairtrade Gold, we now have a 100% ethical, traceable precious metal that gives back to small artisanal miners in some of the most impoverished regions of the world. As licensees with the Fairtrade Foundation, we can create most items in this responsibly sourced precious metal in both Fairtrade 18ct White Gold and Yellow Gold. 


100% Trustworthy Diamond Certification

At Serendipity Diamonds, we work with trusted diamond laboratories. Furthermore, we work to very high standards for all of our certified diamonds. Expect trusted diamond grading reports from laboratories including GIA and IGI along with a minimum cut grade of 'VERY GOOD.' In addition, diamonds exhibit no greater than slight fluorescence.

A Note on Diamond Cut Grade

One of the questions we are asked frequently relates to the cut grade of our diamonds. Australian clients are particularly interested in purchasing a beautifully cut diamond. For this reason, we set our minimum cut grade standard at "VERY GOOD" to ensure maximum brilliance, fire and scintillation. Where applicable this cut grade will be evident on accompanying certification alongside other details including carat weight, colour and clarity. For certification, we favour GIA amongst some of the World's most respected diamond grading laboratories.
