Hi i have a collection of .2 carat round diamonds that ive recycled from old ugly discounted damaged 18kt rings, purchasing for approx $150 aud each. I’m wondering how much a Gia certificate costs in aud and if its worth having them inscribed? I don’t have the details of the diamonds but they all look eye clean and good clear to grey colour. I want to use the diamonds as a retirement fund for when I’m older. I plan on continuing to use the system i have for finding good stones.


Hi tristenne,

Getting these diamonds lab graded may eat up your profit. These diamond sizes are usually sold without lab reports.
