The $21,340 price tag for just 17 units

The new Liquid Metal iPhone Duo represents a massive leap in cost compared to standard consumer electronics. According to the report, the 256GB version is priced at $18,840,while the most expensive 2TB model reaches a peak of $21,340. This pricing structure places the custom device at roughly ten times the cost of Apple's standard iPhone Duo, which retails in the UK between £1,999 and £3,199.

This extreme scarcity is a hallmark of Caviar's business model. By limiting the sterling silver Liquid Metal edition to only 17 pieces, the company creates an immediate sense of urgency and exclusivity for high-net-worth collectors. The pricing scales significantly with storage capacity, moving from $18,840 for the entry-level luxury model up to the $21,340 flagship.

Sterling silver and "frozen motion" aesthetics

Caviar's design for the Liquid Metal iPhone Duo focuses on a sculptural, mirror-finished sterling silver exterior. The company claims the surface is intended to evoke the appearance of metal frozen in motion, using shifting reflections to create a sense of depth. This aesthetic choice was reportedly inspired by the unique way the iPhone Duo folds open, aiming to turn the smartphone into a seamless metallic composition.

This move toward extreme material customization follows a pattern of high-concept luxury releases from Caviar.. The company has previously gained attention for unusual bespoke projects, such as an iPhone 17 Pro Max that incorporated a piece of Steve Jobs's iconic turtleneck.. Such projects signal a broader trend where high-end technology is treated less as a functional tool and more as a canvas for sculptural art and historical tribute.

The $88,290 Palmette 18K gold alternative

Beyond the foldable Duo, Caviar is also offering 76 custom versions of the iPhone 18 Pro and iPhone 18 Pro Max. These variants range significantly in price, with the most expensive model, the Palmette 18K, reaching a staggering $88,290. This specific model features an Art Deco design crafted from 18K gold and decorated with a palm-leaf motif inspired by the United Arab Emirates.

The Palmette 18K is heavily embellished with more than one hundred hand-set diamonds. As the source reports, even the Apple logo on these high-end models is adorned with precious stones to emphasize the purity of the form. These luxury variants exist alongside much more accessible flagship devices, such as the standard iPhone 18 Pro models that start at £1,199.

The missing details on the Liquid Metal buyer

While the technical specifications and pricing of the Liquid Metal series are clear, several questions remain unanswered. The report does not specify whether these 17 units are available for immediate purchase or if they require a bespoke commission process. Additionally , it is unclear if the sterling silver construction impacts the physical weight or the long-term durbaility of the foldable mechanism.

The report also lacks information regarding the target demographic for such a niche release. It remains to be seen whether these devices are intended as functional smartphones or purely as static collector's items. Finally, the source does not include any commentary from Apple regarding these third-party luxury modifications to their hardware.
