Australian Argyle Pink Diamonds
Authorised stockists of one of the rarest gemstones on earth. Every piece in our collection contains a genuine Argyle pink diamond; no substitutes, no imitations.
The Mine Is Closed. The Stones Remain.
The Argyle diamond mine in the East Kimberley region of Western Australia closed in 2020. For nearly four decades it was the world's primary source of pink diamonds, producing more than 90% of the global supply.
Since closure, no new Argyle pink diamonds have entered the market. The stones that exist today; in rings, pendants, and private collections; are all there will ever be. That finite supply is why collectors and jewellers around the world treat Argyle pink diamonds as both a personal treasure and a genuine rarity.
At Allgem, we do not trade in generic "pink diamonds." Every Argyle stone we sell is verified and sourced through authorised channels. If you are considering a purchase, we encourage you to ask questions, view the certification, and take your time. This is not a decision to rush.
Why Buy Argyle Pink Diamonds from Allgem?
We are not a franchise or a chain. We are a single-family jewellery business that has operated from the same Perth address since 1997. Our reputation depends on honesty, not volume.
Alfie Gryg, our registered valuer, examines every Argyle pink diamond that enters our collection. We verify certification, confirm origin, and price based on current market realities, not aspirational markups. If a stone does not meet our standards, we do not stock it.
Because we manufacture and set our pieces in the workshop beneath our showroom, you can see exactly how your stone will sit in its setting before any work is done. Your diamond never leaves the building until it leaves with you.

See Them in Person
Argyle pink diamonds are difficult to photograph accurately. The colour shifts with the light, and every stone has its own character. The best way to choose is to visit our showroom at 653 Hay Street Mall, inside the London Court building.
We offer private viewings by appointment, where you can examine stones under proper lighting, ask Alfie or our team questions, and take the time you need to decide.
No pressure. No rush. Just honest advice from a family who has been in the trade since 1978.
