Karelian Share Price (KDR)

You can see why they endured and waited approx 8 years to get the mining permission over the line. Lahtojoki more important to the bigger picture than many are aware. It’s strategically important and could be a very lucrative revenue stream for KDR + potential partners.

If 5% of Lahtojoki’s diamonds were pink, the project would shift from “interesting” to potentially extraordinary — even though the deposit is small.

Why that percentage is massive in diamond‑industry terms:

1. Argyle produced <1% pinks — and that made it the most profitable diamond mine in history

Argyle’s pink diamonds were:

0.1–1% of production

Yet they generated over 90% of the mine’s profit in its final decade

Individual stones sold for £10,000–£1,000,000+ per carat

So if Lahtojoki produced 5% pinks, that is 5–50× higher than Argyle’s pink proportion.

Even a tiny mine becomes financially powerful with that kind of colour frequency.

2. What 5% pinks would logically mean for Lahtojoki:

Gem quality: ~60%

Already extremely high.

If 5% of total stones are pink:

That means 8–10% of gem‑quality stones are pink

This is unheard of in kimberlite mines

Even 1% pinks would be exceptional

5% would put Lahtojoki in a category of its own

Value impact

Pink diamonds typically sell for:

10× to 100× the price of white diamonds

Sometimes 1000× for intense or vivid stones

So even a small number of pinks massively increases:

Revenue per tonne

Mine life value

Investor interest

Strategic importance (post‑Argyle pink shortage)

3. What this would do to the economics

Even a small mine with:

Moderate grade

High gem quality

5% pinks

…would likely achieve:

£200–£500 per tonne rock value

This is the range where small kimberlite mines become highly profitable.

For comparison:

Many profitable kimberlite mines operate at £50–£100 per tonne

Argyle’s lamproite was only £20–£40 per tonne, but pinks made it a super‑mine

Lahtojoki could outperform Argyle per tonne if pink frequency were truly 5%.

4. Is 5% pinks realistic?

Here’s the honest, grounded assessment:

What we know:

Pink diamonds have been recovered from Lahtojoki

Finland’s mantle conditions can produce colour centres

The gem quality is unusually high

What we don’t know:

The true frequency of pinks…. But has been indicated between 3 -5%

Whether the southern lobe has a higher concentration

Whether deformation processes match Argyle’s pink‑forming mechanism

5% is possible but unproven

If future bulk sampling confirms anything above 1% pinks, Lahtojoki becomes a globally significant coloured‑diamond source.

If it truly hit 5%, it would be one of the most valuable small diamond deposits on Earth.

Bottom line

If Lahtojoki produced 5% pink diamonds, then:

The mine’s value would increase dramatically

It would outperform many larger kimberlite mines

It would become one of the world’s few sources of natural pinks post‑Argyle

Even small annual production would command premium auction prices

5% pinks would make Lahtojoki a boutique but extremely high‑value mine.

60% gem‑quality is very high for a diamond deposit. In fact, it puts Lahtojoki in the upper tier of global kimberlite mines in terms of diamond quality.

Here’s the context that makes that number meaningful:

What “gem quality” usually looks like in diamond mines

Most kimberlite mines produce a lot of industrial diamonds and a smaller proportion of gems.

Typical ranges:

Low‑quality deposits: 10–20% gem quality

Average kimberlite mines: 20–40% gem quality

High‑quality deposits: 40–55% gem quality

Exceptional deposits: 60%+ gem quality

So 60% gem quality is not just good — it’s elite.

Only a handful of mines globally reach or exceed that level.

Why 60% gem quality matters

High gem percentage means:

Higher price per carat

Lower waste per tonne mined

More consistent revenue

Better economics even at small scale

Greater sensitivity to coloured stones (because they are counted within the gem fraction)

For a small deposit like Lahtojoki, high gem quality is critical — it’s what makes the project potentially viable.

And if coloured diamonds are present…

Even a tiny fraction of pinks or fancy colours can dramatically increase revenue.

Argyle’s pinks made up less than 1% of production, yet generated over 90% of the mine’s profit in its final years.

So a deposit with:

60% gem quality, and

some coloured stones already recovered

…has a very attractive value profile, even if the total tonnage is modest.

Bottom line

60% gem quality is extremely high. For Lahtojoki, it’s one of the strongest indicators that the project could be commercially valuable, especially if coloured stones continue to appear.

That one is for hooops!

From Finland’s frozen fields they gleam,

Pink diamonds with a secret glow—

As if the Arctic learned to dream

In shades of rosy snow.

They hide beneath the winter’s hush,

Where silent crystals guard the cold,

Until the earth begins to blush

And lifts its treasures bold.

But these aren’t gems you find each day—

They’re rarer than a northern spring,

A whispered fortune tucked away,

A quiet, shimmering king.

Some say they’re drops of dawn so pure

That even sunlight can’t replace,

A rosy spark the world ensures

Is priced like bottled grace.

Collectors chase them far and wide,

For every stone’s a whispered tale—

A blush of Arctic pride

inside A jewel too rare to fail.

So Finland sparkles, soft yet grand,

A wink beneath the polar sky—

Pink diamonds worth a kingdom’s land,

A treasure money can’t deny.
