LONDON, July 5, 2026, 17:03 (BST)
- Gem Diamonds Limited (LON:GEMD) finished Friday trading with late London quotes in the 3.40p-3.50p range, leaving the company valued at under £5 million.
- The stock dropped around 5.6% last week. The FTSE All-Share rose about 1.6% over the same period.
- Q1 revenue came in at $32.1 million, or close to £24 million using Friday’s exchange rate. That’s about five times what the market says the company is worth.
- This week, traders watch Q2 large-stone sales, the bid-offer spread, and the December 2026 debt-facility renewal for the group.
Gem Diamonds Limited (LON:GEMD) opens the week in London with some big numbers that stand out. The miner reported first-quarter sales at about five times its current market cap, yet shares still look stuck at micro-cap levels. ADVFN, using data from the London Stock Exchange, showed the last automated trade on Friday at 3.40p, up 3.03%, giving a market cap of £4.76 million. MarketWatch’s delayed quote had the price at 3.50p, up 6.06%, and a £4.9 million market value.
The split is showing up in the market. Hargreaves Lansdown quoted a 3.29p sell and 3.71p buy, a spread of around 12.8% of the sell price. Volume was 193,420 shares on Friday. That spread matters—a small buyer is down right away unless an RNS drops.
| Last-week tape | Gem Diamonds | Market read-through |
|---|---|---|
| Friday quote range | 3.40p-3.50p | Vendors show different quotes, low liquidity |
| Bid / offer | 3.29p / 3.71p | Entry is costly on the spread |
| One-week move | -5.6% | Stock still down for the week |
| One-month move | -19.2% | Downtrend continued this month |
| One-year move | -48.3% | Shares keep falling, no sign of a comeback |
| FTSE All-Share, last week | +1.6% | London stocks finished the week higher |
The FTSE All-Share finished Friday at 5,735.46, gaining 0.28%. The index was also higher from 5,643.44 on June 26. Reuters reported the FTSE 100 was up 0.2% for the day, posting a weekly gain with support from financials and precious-metals miners. Gem Diamonds missed out on those broad gains.
The revenue-to-equity gap is key for investors here. Gem reported Q1 revenue at $32.1 million, with $7.0 million from selling a set of 10 diamonds over 10.80 carats. Using Friday’s sterling rate of $1.335, that’s about £24 million in revenue for the quarter. The market is valuing the company at around £4.8 million to £4.9 million.
| Letšeng metric | Q1 2026 | Q4 2025 | Change |
|---|---|---|---|
| Carats recovered | 21,605 | 20,961 | +3% |
| Carats sold, excluding extra parcel | 16,727 | 21,191 | -21% |
| Total value, excluding extra parcel | $25.1 mln | $27.3 mln | -8% |
| Average price | $1,501/ct | $1,288/ct | +17% |
| Four stones above $1 mln | $9.9 mln total | n/a | n/a |
| Top Q1 price | $32,908/ct | n/a | n/a |
Gem said most Q1 output came from the lower-grade Main Pipe, with less from the higher-grade Satellite Pipe. Some carats moved into Q2, and a 100.71-carat Type I faint yellow diamond found in Q1 will be sold in Q2. So, near-term sales will depend more on timing than volume from the mine.
Debt and sluggish rough-diamond demand are in focus, with revenue taking a back seat. Gem’s 2025 earnings showed a 36% fall in revenue to $98.4 million and underlying EBITDA down 87% to $3.9 million. The company booked a $77.5 million impairment at Letšeng and reported net debt of $20.1 million as of Dec. 31. CEO Clifford Elphick said “continued weakness in the diamond market” pushed the company to take “decisive action.” The numbers also show Gem’s revolving credit facilities expire in December 2026, with the accounts carrying a material uncertainty on going concern. That’s because the renewal is inside the 12-month review window. Gemdiamonds
Industry numbers point both ways. Business Insider said July 4 that natural diamonds are seeing pressure on lower-end stones but demand is holding up for bigger or rare diamonds. Dan Mano, CEO of Rapaport, called the “diamond market… increasingly bifurcated.” Edahn Golan at Tenoris said lab-grown diamonds are hurting “the most painful category,” with Paul Zimnisky noting some buyers want “the real thing again.” Business Insider
The split is a better fit for Letšeng than most, but the balance sheet is still an issue. Gem holds 70% of Letšeng in Lesotho. The company says the mine is known for producing big, exceptional white diamonds, and calls it the top kimberlite diamond mine in the world by dollar-per-carat. In July, Gem reported 141.5 million ordinary shares in issue, with 1.52 million in treasury, leaving 140.0 million voting rights.
Board leadership at the company has changed. Mike Brown stepped in as non-executive chair after the June 3 AGM, taking over from Harry Kenyon-Slaney, who served for nine years. Kenyon-Slaney said the transition offered “continuity” as the company navigates a “period of heightened complexity.” At the same meeting, around 16% of votes went against re-electing Brown, Elphick, and CFO Michael Michael.

No trading update followed the July 1 total voting-rights notice, based on the most recent Investegate RNS list as of Sunday. Stockopedia’s calendar puts the half-year 2026 earnings out on Sept. 7, 2026. That leaves the stock facing Monday’s open with price spread, Q2 sale hopes and a possible unscheduled RNS.
