Namibia unveils a 176.29-carat diamond found on 10 May

What changed
A large rough, no price. NAMDEB has unveiled a 176.29-carat natural diamond found at Oranjemund on 10 May 2026. No valuation, tender date or buyer accompanies it.
What it means
- If you buy large rough: There is nothing to bid on yet. No tender, no reserve and no date were given.
- If you track Namibian beneficiation: The call for domestic cutting carries no target, timetable or capital figure to measure.
- If you price by weight: 176.29 carats is the only hard number in the announcement. Everything else is characterisation.
- What this is not: A sale. Owishi has been shown, not sold, and no price is implied by its weight.

No valuation was disclosed
The absent number. The report gives no estimate, no tender date and no buyer for a gem-grade rough of 176.29 carats.
Nothing substituted. No per-carat comparison is printed here, because a weight alone does not price a stone of unknown colour and clarity.
| Item | Value | Source states it |
|---|---|---|
| Rough weight | 176.29 carats | yes, in the headline and body |
| Date of recovery | 10 May 2026 | yes, in the body |
| Date of unveiling | 5 October 2026 | yes, the page's own byline date |
| Interval, find to unveiling | 148 days | no — Carat Capital's count |
| Largest of its kind at the mine in | two decades | yes, attributed to the operator |
| Valuation, tender date or buyer | none | no — absent from the report |
| Government–De Beers split | 50/50 | yes, cited by the president |
Notes on this table
Every row marked yes is read out of the report's own article text, below the site's navigation block, not from the page furniture. The 148-day interval is Carat Capital's own count from 10 May 2026 to 5 October 2026 and is labelled as such. The valuation row is a negative claim and is established by search rather than assertion: the saved file was greped for a currency mark, for carat and for tender, and no price, estimate, reserve or sale date appears anywhere in the article text. Carat weight is the only quantity in the announcement that a market could act on.
Five months from pit to podium
A long interval. The stone was recovered on 10 May 2026 and shown on 5 October, 148 days later on Carat Capital's count.
Two decades claimed. NAMDEB describes it as the largest of its kind recovered at the Southern Coastal Mine in the past twenty years.
The partnership is half-owned
Fifty-fifty split. President Nandi-Ndaitwah cited the government's 50/50 partnership with De Beers Group as a model of public-private development.
A request only. She asked for commercially viable domestic cutting and polishing. No target, timetable or capital figure accompanied the request.
What to watch
- Next NAMDEB or Namib Desert Diamonds tenderWhether Owishi is offered and at what reserve. The announcement names no sale channel.
- Through Q4 2026Any valuation or sale price attached to the stone. Until one exists, the weight is the only number.
- Namibia's next budget cycleWhether the call for domestic cutting acquires a target or a capital figure.
The story so far
Go deeper
What would change this call
A disclosed valuation. A tender reserve or sale price would turn this from a weight into a priced stone, and would be the first number in the story a buyer could act on.
Why a rough weight is not a price
A rough diamond's value is set by colour, clarity, shape and expected polished yield, not by carats alone. Two stones of the same weight can differ by more than an order of magnitude in realised price once a cutter models the yield. Large gem-grade rough is normally sold by tender or special arrangement rather than at a list price, which is why a weight published without a tender gives a market nothing to work with.
Method
The GJEPC page was fetched to raw bytes, HTTP 200, 33,730 bytes, saved to newsroom/sources/2026-10-06/owishi.html, and its article text was isolated from the site's long navigation block before any figure was read. Exact-digit greps on the saved file: 176.29 six hits, Owishi eight, Namibia twelve. The page's own byline reads Oct 05, 2026 and the find date 10 May 2026 appears in the body. Archive check: grep -ril -F 'Owishi' website/ returns zero files, so the stone is new to this archive by name as well as by event. The negative price claim was established by searching the saved file rather than asserted: no currency mark, estimate, reserve or tender date appears in the article text. The stone is carried as solid but single-source — GJEPC is the only outlet reached that reports the unveiling, and no second primary was found to cross the 10 May find date against. That limit is disclosed rather than smoothed over. No quote is carried: the president's remarks are reported in GJEPC's own summary rather than quoted verbatim, so there is nothing under the cap to lift.
