From De Beers viewing to your finger, one mile, one hand.

We cut them.
You wear them.
Nothing in between.

Only natural diamonds. Only certified. GIA & EGL. Only stones that hold their cut.

Twenty-five years in South African diamonds. Most of the rough comes through the De Beers Johannesburg viewing room (D and D Diamonds is a DBCM Emerging Beneficiation Customer since 2019); the rest from independent SA diggers Prodiam has worked with for decades. Polished to ideal cut on our Bedfordview bench, sold in the same building as GIA South Africa, by the same hand from rough to ring. Directed by Darren Lance Etkind. South Africa’s director-led diamond house.

South Africa’s diamantaire.

Darren Lance Etkind. The man behind every Prodiam stone.

Every viewing at De Beers, every stone on the bench, every commission and trade-account decision passes across this desk. That’s the only honest way to say wholesale. Darren Lance Etkind

What we do

Cut Polish Design Source Manufacture Trade Finance

One Etkind operation. One address in Bedfordview. Procut DCW buys the rough at De Beers viewings and polishes to GIA Excellent / AGS Ideal cut grade. Prodiam Trading markets, sells, and finances the polished output. Every stone has its own story. We know it, because we sourced it.

Sourcing & bespoke

The website is a sample. The bench is a network.

What you see online is a curated slice of what we have moving through the bench. The full Etkind operation reaches further: De Beers DBCM viewings in Johannesburg, the State Diamond Trader, tender houses in Kimberley, Wolmaransstad and Schweizer Reneke, and twenty years of independent-digger relationships. If you have a brief, we source to it.

  • Source on demand

    Tell us what you want. We find it.

    Any shape, any cut, any colour, any clarity, 0.30 ct to 10 ct +. GIA-certified or EGL on request. Bench-priced because we cut it ourselves, not because we marked something down.
