You’d think the most expensive phone in the world would be some futuristic piece of tech that can project holograms or fold into a paperclip. Honestly, it’s the opposite. The device that currently holds the record for the highest price tag—a staggering $48.5 million—is actually a decade-old iPhone 6.
It’s called the Falcon Supernova iPhone 6 Pink Diamond.
If you're wondering why someone would pay the price of a private jet for a phone that probably struggles to run the latest version of Instagram, you aren't alone. But in the world of the ultra-wealthy, specs like RAM and processor speed don't matter. What matters is the 24-carat gold and the massive, rare pink diamond bolted to the back.
The $48.5 Million Question: What is the Most Expensive Phone in the World?
Basically, the Falcon Supernova isn't a phone; it's a piece of jewelry that happens to make calls. Commissioned by Nita Ambani, the wife of Indian billionaire Mukesh Ambani, this device isn't something you'll find at a Best Buy.
The "base" model of this luxury line starts with a 24-carat gold casing. You could also get it in platinum or rose gold if you were feeling particularly "modest." But the real kicker is the gemstone. The Pink Diamond edition is the holy grail. There are other versions with "cheaper" orange or blue diamonds that cost around $42.5 million, but the pink one is the undisputed king.
Why the price tag?
- The Diamond: Pink diamonds are among the rarest on Earth.
- The Casing: Solid gold or platinum throughout.
- Exclusivity: It is a one-of-a-kind bespoke build.
- Security: Falcon reportedly added a layer of encryption that goes beyond standard Apple security (though, let's be real, it's an iPhone 6).
The Runners Up: Stuart Hughes and the Gold Kings
If $48 million feels like a bit much for your budget, the "second-tier" of expensive phones still costs more than most mansions. For years, the name Stuart Hughes has been synonymous with tech-based opulence.

Take the iPhone 5 Black Diamond, for example. Valued at roughly $15 million, it was commissioned by a Chinese businessman who actually provided the black diamond himself. It’s a 26-carat deep-cut black diamond that acts as the home button. The rest of the phone is encrusted with 600 white diamonds.
Then there’s the iPhone 4S Elite Gold. At $9.4 million, it’s a heavy hitter. The bezel is handmade with 500 diamonds (totaling 100 carats). The coolest—or maybe weirdest—part? The chest it comes in is made of solid platinum and contains actual fragments of T-Rex dinosaur bone. Talk about a conversation starter at a dinner party.
A Quick Reality Check on Costs
To put these numbers in perspective, you could buy about 40,000 standard iPhone 17 Pro Max units for the price of one Falcon Supernova. It’s a level of wealth that is hard to wrap your head around.
Modern Luxury: Caviar and the Vertu Legacy
Nowadays, you don't see as many $40 million custom builds. The market has shifted toward brands like Caviar. They take the latest tech—like the iPhone 17 or the Samsung Galaxy S26—and give them the Midas touch.
Caviar’s "Snowflake" edition, often priced around $560,000, is a current favorite for those who want modern features with billionaire aesthetics. They use Graff diamonds and 18k white gold. The difference here is that you actually get a phone with a modern camera and a battery that lasts longer than twenty minutes.

And we can't talk about expensive phones without mentioning Vertu. While they went through some rocky financial years, the Vertu Signature Cobra (around $360,000) remains a legend. It features a literal cobra wrapped around the edges, made of 439 rubies and two emeralds for eyes. It’s loud, it’s garish, and it’s exactly what people mean when they talk about "old money" luxury tech.
Does the Tech Even Matter?
Honestly, no.
When you buy the most expensive phone in the world, you are buying a status symbol. These phones are terrible investments if you're looking at them as "mobile devices." The hardware becomes obsolete in three years. The software stops updating. Eventually, the apps won't even open.
But gold and diamonds? They don't have an expiration date.
Most owners of these devices treat them as museum pieces or "safe" investments. They are often kept in literal safes, coming out only for high-profile events. It's a weird niche where the "phone" part is the least interesting thing about the product.

The Security Aspect
One legitimate reason (besides the diamonds) that people buy these custom devices is privacy. Companies like Gresso and the makers of the Diamond Crypto Smartphone ($1.3 million) claim to use proprietary encryption. In a world where high-net-worth individuals are constant targets for hacking, a "dumb" phone with heavy-duty encryption is actually a pretty smart move.
What You Should Look for Instead
Unless you have a few million dollars burning a hole in your pocket, you’re probably looking for a "normal" expensive phone. For 2026, that means looking at the top-tier flagship models.
- Check the Materials: If you want luxury without the $48 million bill, look for Titanium or Ceramic finishes.
- Look at Caviar: They offer "mid-range" luxury (around $7,000 - $12,000) that uses real gold plating on current-gen iPhones.
- Prioritize Longevity: A phone is only as good as its software support. Stick to brands that offer 7+ years of updates.
The world of ultra-luxury phones is wild. It’s a mix of ancient gemstones, dinosaur bones, and (sometimes) outdated circuitry. While the Falcon Supernova remains the king of the mountain, the trend is moving toward functional luxury—phones you can actually use to take a photo, even if that photo is of your own solid-gold home button.
If you are curious about getting a taste of this lifestyle without selling your house, your best bet is to look into custom plating services or high-end designer cases from brands like Gray or Labodet. They give you the weight and feel of a premium device for a fraction of the "billionaire" price tag.
