Provenance Report

Without an Australian pink diamond provenance report there is no way of guaranteeing the authenticity of your pink diamond. The report features a unique lot number and outlines the diamond’s carat weight, shape, clarity and colour.

The provenance of each Australian pink diamond is maintained through audited controls in the mining, polishing and distribution of every gem, ensuring a guaranteed chain of custody from mine to market.
