Natural Fancy Argyle Pink Diamonds
Argyle pink diamonds are natural pink diamonds with documented provenance from Rio Tinto's former Argyle mine in Western Australia. The mine ceased production in November 2020 after 37 years of operation.
Understanding Fancy Argyle Pink Gems
Geological Origin
Argyle diamonds were recovered from a lamproite deposit. GIA research associates the pink-to-red color of most natural diamonds in this range with a 550 nm absorption band linked to plastic deformation, while the precise atomic defect remains unidentified.
Hue & Secondary Overtones
Argyle used proprietary color terminology for selected stones, separate from GIA's hue, tone, and saturation system. The two systems should not be treated as direct equivalents. Buyers should inspect the original provenance documents, inscriptions, and any independent laboratory report supplied with a stone.
Market & Valuation
The Argyle mine no longer produces diamonds, but stones with Argyle provenance continue to circulate through private and public markets. Provenance, color grade, documentation, carat weight, clarity, cut, and condition all affect comparison between stones.
Fancy Color Intensity Scale
GIA describes colored diamonds using nine grade terms from Faint through Fancy Dark. The terms reflect hue, tone, and saturation; they are not a linear price scale. See the GIA fancy color diamond grading guide.
Key Facts
Evaluating Argyle Pink Diamonds
An Argyle origin does not by itself establish a current value or future return. Buyers should verify the documentation and compare the complete characteristics of the specific diamond with current transactions for stones of similar provenance and grade.

Argyle Pink Diamond FAQ
Why did the Argyle mine close?
Rio Tinto's Argyle diamond mine in Western Australia ceased production in November 2020 after 37 years of operation. The closure ended new production from that specific deposit; it did not end the occurrence or trade of natural pink diamonds from other sources.
How do I authenticate an Argyle diamond?
Authentication depends on the documents and identifiers supplied with the individual stone. Compare any Argyle provenance document, tender record, or laser inscription with the issuing records, and verify an independent laboratory report directly with that laboratory when one is provided.
How much have Argyle pink diamonds appreciated since the mine closed?
There is no universal appreciation percentage that applies to every Argyle pink diamond. Results vary with provenance, documentation, color grade, size, clarity, cut, condition, and the transaction date. Current comparable sales are needed to evaluate a particular stone.
Are all pink diamonds from the Argyle mine?
No. The Argyle mine was an important historic source, but natural pink diamonds have also been recovered from deposits outside Australia. Argyle provenance must be documented and should not be inferred from the diamond's color or appearance.
