24k GOLD iPhone case owned by Kylie Jenner and Khloe Kardashian

When you buy a new phone, you have two options; protect it from the world in a thick military-grade case, or, of course, cover it with priceless diamonds.

It turns out that some celebrities such as Kylie Jenner And Khloe Kardashianwent to the last and bought yourself some of the most luxurious iPhone cases around.

Plated in 24 carat gold, the stars’Keep up with the Kardashiansspent $599 (£504) each on cases from Golden Concept.

But those aren’t the only stars who own luxury accessories, as the company also sells the world’s most expensive Apple Watch case.

This “Diamond Edition” case is crafted from a solid block of aerospace titanium and contains 443 diamonds, valued at a whopping $15,000 (£12,500).

They are owned by only seven people in the world, including Middle Eastern royalty and the chart-topping American rapper, although the company’s CEO Puya Shamsossadati did not reveal who.

“Over the years, we’ve had some unusual requests,” he told MailOnline.

“One asked for an iPhone case featuring the Hindu deity Ganesha cast in solid gold and encrusted with diamonds. It costs about a quarter of a million dollars.

He added that adult film companies also commissioned products for their talents, which were engraved with their autographs.

“We clearly have something for everyone!” Mr. Shamsossadati told MailOnline.

The businessman from Malmö, Sweden claims that Golden Concept products are the modern equivalent of owning a luxury car and “the opposite of the fast fashion of plastic accessories.”

All precious cases are shipped in recyclable engraved wooden cases.

Mr. Shamsossadati said: “Items like a phone or a watch are used and constantly looked at, and they are also what other people see you with.

It’s hard to stand out when, when it comes to the iPhone, hundreds of millions of people have exactly the same product as you.

“We allow people to express their individuality through accessories.”

But the Kar-Jenners aren’t the only celebrities sporting some jewelry on their gadgets, as Brazilian soccer player Neymar Jr owns at least three Apple Watch cases worth $1,999 (£1,653) each.

They are made of gold-plated stainless steel or titanium and are adorned with 200 Swarovski crystals.

Football legend Lionel Messi and hit-maker DJ Khaled also own 18k gold-plated iPhone cases worth a whopping $5,000 (£4,142).

But some smartphone case designers prioritize function over fashion, and one Mous allowed the iPhone 14 to survive launch during a bungee jump.

Mous CEO and co-founder James Griffith took part in the terrifying jump during which he dropped Apple’s flagship smartphone from a height of 20 meters above the ground.

Surprisingly, both the smartphone and the smartphone case survived the test unscathed.

“I don’t know what’s scarier – jumping from such a height or throwing a brand new iPhone 14!” he joked.

However, both Mous and Golden Concept may not yet have mastered the next big trend in smartphone cases, faux leather.

Scientists from the University of Bristol have developed a prototype skin that they say can wrap devices such as smartphones to provide a “more natural interface”.

Designed to look and mimic human skin, it responds to various forms of human contact such as tickling, petting and pinching.

The researchers say their work opens the door to a possible future with “anthropomorphic devices” where things have human characteristics.

The artificial skin was created using two layers of silicone—the “dermis” and “hypoderm” layers—with a layer of electrodes in the middle, made up of ultra-thin wires that act as sensors.

Two different types of silicone were dipped in pigment and molded to give the creation a leather-like texture.

The researchers said their artificial skin allows the devices to “feel the user’s grasp” and has the ability to “detect interactions such as tickling, petting, even twisting and pinching.”
