I always assumed the diamond market was dead. Killed off by lab-grown diamonds.

Turns out I was only half right. The generic market is hurting, but ultra-rare pink stones are quietly up 5x over the past 20 years. (Including those gorgeous pink argyle diamonds from Australia)

This week, third generation diamond dealer ​Viral Kothari​ takes us through the ​diamond market​: an alternative asset in the middle of a huge transition.

Check out this great issue + Viral’s new Diamond company ​Aquaduct​

​Halter​, a New Zealand agtech startup, just raised $165M in Series D funding (led by Bond), pushing its valuation to US$1 billion.

The company makes solar-powered smart collars that use geofencing, sound, and vibration to let farmers virtually herd cattle — no physical fences or herding dogs required. It’s already working with 150 ranchers across 18 U.S. states.

With fresh capital, Halter is expanding across NZ, Australia, and the U.S., riding a wave of VC interest in sustainable, tech-enabled farming.

UK “Carbitrage”

Typically, ​importing a car from the UK to the US​ is so expensive that it’s not worthwhile. Between customs, duties, tariffs, ​federalization​, and shipping, costs can run well into six figures for a luxury vehicle.

However, if the car is ​25 years or older​, you are exempt from paying most of those fees, specifically, the Trump tariffs and federalization.

This works best for enthusiast vehicles with limited supply, like the Ferrari F355 and air-cooled Porsche 911s. The margin on lower-tier cars evaporates with shipping, insurance, and other expenses.

​Auto I​ is a new three-year investment opportunity by exploiting a legal import loophole in the U.S. for classic cars.

Thesis: Once a vehicle is 25+ years old, it’s exempt from emissions and safety regulations, allowing certain UK cars to be imported and sold at much higher U.S. prices.

Strategy: Buy iconic LHD (left-hand drive) UK vehicles. import them to the U.S. duty-free, and sell within ~6 months.

This is a follow-up to Altea’s successful Film I deal — same model, different asset class.

Artwork

There’s a collection of art in Geneva ​valued​ at more than $10B. It’s thought there are ​over a million paintings​, and the facility is the size of 30 football fields.

There are ​similar sites​ in Luxembourg, Monaco, Singapore, Zurich, Beijing, and … Delaware.

The home of billions worth of priceless art.

These sites are called ​freeports​, and they’re a remarkable economic invention.

A free port facilitates “the temporary exemption of taxes for an unlimited quantity of time.” Put another way, it’s a giant warehouse used to stash art, antiquities, wine, gold, jewels, and other priceless artifacts and never pay tax on them.

They exist outside the formal jurisdiction of any country; the clients remain anonymous and the assets are kept a secret.

And though you may have never heard of free ports, they’re a big deal in the art world

The ​whiskey market​ is cooling after years of hype.

Cask firms have collapsed, investors have been left in the dark, and many are now realizing that a certificate isn’t the same as ownership. Warehouses couldn’t verify claims. Transparency wasn’t just lacking—it was nonexistent.

But the market isn’t dead. It’s evolving.

Smarter platforms now offer real custody, insurance, and exit options. Producers are exploring asset-backed structures that actually align investor capital with real-world inventory. Less hype, more infrastructure.

That’s all we have!

See you next time, Stefan
