✓Every stone shown here passes the Procut Screen, the quality gate our cutting house runs before a stone earns the loupe.What it checks +
Certified by a recognised lab
Natural diamond, never lab-grown
Round brilliants cut to the Excellent class
Polish and symmetry Very Good or better
No I-grade clarity listings, sane proportions, real listed prices, and suspicious below-market pricing screened out
These are hand-picked on the certificate: the cut, polish, symmetry, colour and
clarity Prodiam will stand behind on paper. We have not had these
stones in our hands, because they sit with the supplier until one is ordered, and
we check every one properly when it lands. Switch to the full market if you would
rather look yourself, and
ask us about anything you find.
Want a diamond in your hand this week? These are sourced in, so they

Searching the certified market
No diamonds match that exact spec.
Loosen a filter (widen the carat range, drop the colour or
clarity a grade, or lift the price ceiling) or send us the
spec and we will hand-source it for you.
Tell us your spec and we will quote within 24 hours.
Nothing on the bench matches that exact spec. Tell us what you
are after, shape, carat, colour, clarity, cut and budget, and he
goes through the certified inventory by hand and comes back with
real options and what each one costs.
Every price shown is a real ZAR figure (current market plus today's
exchange rate, our margin built in) and every diamond is certified
natural, never lab-grown. Before any stone reaches this page it
passes the Procut Screen: our cutting house's quality gate covering
certification, cut class on rounds, polish and symmetry, clarity
floors, sane proportions, honest pricing and declared fluorescence.
Stones that fail are not shown at a discount. They are not shown at
all.
Not sure where to start? That is completely normal.
Most people buying a diamond are doing it for the first time, and the whole thing can feel
like a lot. You do not need to know your colour from your clarity before you talk to us.
Tell us roughly what you are after and what you would like to spend, and we will do the
hard part with you. There is no pressure and no obligation, and we would genuinely rather
you asked than guessed.
Not everything has to be ordered in. There is real stock sitting in Bedfordview that
you are welcome to come and look at properly, under a loupe, in daylight, with someone
who can explain what you are seeing. Some of it is on
the loose diamonds page, but that page is only a slice
of what is in the safe, so the quickest answer is always to
ask us what we have. Come past
and take a look, or message first and we will have a few ready for you.
We read the report before you buy, and the stone before you keep it
Be clear on what is what. Anything in our safe in Bedfordview you can see on the loupe
yourself, with us, before you spend a cent. Anything on this page is sourced: it sits with
the supplier until it is ordered, so nobody can put it under a loupe today, and we will not
pretend otherwise.
What we do instead is read the certificate properly. Where the inclusions sit, whether the
fluorescence is likely to turn it hazy, whether the proportions add up. We ask the supplier
for more images where they exist. And when the stone lands here we check it before it goes
to you, so nothing arrives that we would not have bought ourselves.
Ask us about a stone,
or put it to the AI assistant on this page, which reads these reports all day.
Buy the stone, then let us mount it
Plenty of people buy the diamond first and decide on the setting later, and that is a perfectly
good way to do it. Once the stone is yours, tell us what you have in mind and the same bench
that does all our own work will build it around that stone. Ring, pendant, earrings, a remake
of something you have seen.
Talk to us about a setting.
Sourced stones are bought before anyone has seen them
A sourced diamond sits with our supply partner, not in our safe, so nobody has held it
yet, us included. What you do have is the full laboratory report: every measurement,
grade and proportion on this page comes off that certificate, and the report number is
yours to check with the lab before you pay anything. If that feels like a lot to take
on trust, that is fair enough:
send us the stone and we will
tell you honestly what we make of it first.
A sourced stone cannot come back
Once we buy one in for you it is yours, so there is no refund or exchange on a sourced
diamond. We would far rather you took another week and asked us five more questions
than felt rushed into it. If you want to be certain before you commit,
talk it through with us.
That is exactly what we are here for, and it costs you nothing.
Sourcing takes a little time
These stones travel from wherever they are sitting. Each card shows the working days
that particular one needs, and you can sort the whole list by what arrives soonest.
If you need a diamond in your hand this week, that means our own stock instead, and we
almost certainly have something:
message us and ask.
Buy a sourced stone here, or message us for ours
A sourced diamond goes through the checkout on this site at the price shown, and that
price is everything landed in South Africa: the stone, VAT, getting it here, and the
card fee, in one number with nothing to add afterwards. The diamonds already in our
safe are not sold through the checkout, so
message us for those and we will
price them for you directly.
Any stone here can become a finished piece
A loose diamond is a starting point, not the end of it. Anything you find here can be
set into a ring, a pendant or earrings by the same bench that does all our own work.
Tell us what you have in your head, even roughly, when you
message us, and we will design
it around the stone rather than the other way round.
Whatever you are looking for, we will find it
Between the stones in our safe and everything our supply can reach, there is a diamond
here for what you want to spend. If you have not found it on this page, it is because we
have not spoken yet. Tell us the occasion, the budget and anything you already know they
like, and we will come back with real options and a straight opinion on each one.
Send your spec and Prodiam quotes matched certified stones by hand, one fully-landed price in Rands, within 24 hours. Reserved on a deposit; full laboratory report on reserve.
Ask us to quote any stone or ring and you get a firm figure in writing
within 24 hours, VAT inclusive, with the trade-offs explained in plain
English. It costs nothing and commits you to nothing: no deposit, no
account, no follow-up campaign. Worst case, you learned the honest
number and bought elsewhere better informed.
We actually want you to compare. Buying well means weighing options;
it is how we buy rough at the viewings, and it is how you should buy a
diamond. Bring any written quote and we will price it like-for-like,
and if we cannot beat it, we will tell you so bluntly. Either way you
leave knowing where you stand.
One more thing worth knowing: this site shows a selection of our stock,
never the full range. Far more passes across the bench than we ever
list, so if the exact stone or design you want is not here, ask us for
it. It is usually one message away.
Prefer to talk it through first? That works too. Tell us how you like
to be reached, and that is how we will reach you.

168 certified diamonds on the bench, priced and ready
Every bench stone is listed with its grading report.
168 GIA- and EGL-certified natural diamonds are on the
Bedfordview bench right now, each with its report number, full ZAR
price and a verify-at-GIA link. If the stone you want is not among
them, send the spec and Prodiam sources it by hand with a firm quote
within 24 hours.
Most diamond search tools end at the cart. Ours starts a conversation
with a cutting house. When you find the stone you want, you are not
buying from a faceless marketplace. You are commissioning Prodiam,
a director-led South African diamond dealer and cutting house in
Bedfordview, Johannesburg.
We reserve the diamond, send you its full GIA
report, HD photography and 360° video, and only then, once you
have seen it and confirmed, do we cut, set or ship. The same bench
that polishes our loose diamonds can set
your sourced stone into a bespoke
engagement ring, a pendant or a
pair of earrings.
Why the Rand price you see is the real price
Every figure on this page is a live ZAR price: the current wholesale
stone price, converted at today's exchange rate, with our margin already
built in and rounded up to absorb currency movement. There is no retail
counter premium folded in afterwards, and there is no separate
per-carat number to negotiate from. Because we work direct, you see a
wholesale-led price, not a showroom one.
We never display an invented or
placeholder price. If a diamond has no live price, it simply is
not listed, and you can always
send us the spec for a
hand-prepared quote.
Certified, natural, and verifiable
Prodiam works in natural, mined-Earth diamonds only (never
lab-grown), and every stone is independently certified so you can compare
like with like on the grades that matter: colour, clarity, cut, polish,
symmetry and fluorescence. Each listing names its laboratory, most
commonly GIA. You receive the full laboratory report when
you reserve the stone, and you can verify it yourself before you settle.
If you would like, we can request light-performance imaging (ASET
or Hearts-and-Arrows) on a stone, the one axis a cutting house can
speak to that an online store outsources. Read
the 4Cs of diamond grading and
how to read a GIA report
before you set your spec.
Sourcing a diamond: common questions
How does sourcing a diamond to my spec work?+
You set the shape, carat range, colour, clarity, cut, fluorescence and your budget, and we work the brief by hand against the bench and the wider supply lines: De Beers viewings, tender houses and thirty years of trade relationships. You get a short set of matched certified options, each with the full gemmology and a single, fully-landed ZAR price, wholesale-direct, with no retail counter markup, within 24 hours.
When a stone is right, you reserve it with a deposit, we send you the full GIA report and HD photography and 360 video, and you confirm before anything is cut, set or shipped.
Is the price I see the final price, in Rands?+
Yes. Every price shown is a real, final figure in rands: the current wholesale stone price converted at today's exchange rate with our margin already included, rounded up to protect against currency movement. There is no separate per-carat or wholesale figure to back into, and no hidden retail premium added later.
We quote firm, VAT inclusive, before any work begins, and we never send an invented or placeholder price; every figure you receive from us is a written quote Prodiam will stand behind.
Are the diamonds certified and natural?+
Yes. Prodiam sources natural, mined-Earth diamonds only, never lab-grown. Every stone carries its own independent laboratory report, most commonly GIA and otherwise IGI or HRD, and each listing states which. You receive the full report once you reserve the stone, and you can verify it yourself against that laboratory's own report-check service before you settle.
The site shows you only the certified grades, shape, carat, colour, clarity, cut, polish, symmetry and fluorescence, so you compare like with like.
Can you cut, set and deliver the diamond I source?+
Yes, that is the Prodiam advantage. We are a cutting house in Bedfordview, Johannesburg, directed by Darren Etkind, not a drop-ship store. We can supply the loose stone, or cut and set it into a bespoke engagement ring, pendant or pair of earrings on our own bench, and request light-performance imaging such as ASET or Hearts-and-Arrows on the stone for you.
The finished piece is delivered insured overnight anywhere in South Africa, with a written valuation for insurance.
