**SINGAPORE — Put a rare diamond beside gold or platinum and nobody asks why it is valuable. Put the same diamond into iron, aluminium or bronze, however, and suddenly the definition of luxury becomes a much more interesting question.**

That question has become one of the signatures of **Hemmerle**, the independent Munich jewellery house that has spent decades deliberately ignoring one of high jewellery's oldest assumptions: that exceptionally valuable gemstones must always be surrounded by conventionally precious metals.

From **September 10 to 12, 2026**, the fourth-generation German jeweller will present a selection of its one-of-a-kind creations in Singapore during private, appointment-only viewings. CNA Luxury reports that the presentation will take place at **The Singapore EDITION** in partnership with Singapore jewellery specialist **Revival Jewels**. Hemmerle's own current events calendar independently confirms its Singapore private viewings on those dates.

Yet the real story is not simply that expensive gemstones are being placed inside comparatively inexpensive metals.

It is why collectors are prepared to treat the finished objects as high jewellery anyway.

## A diamond-and-iron ring changed Hemmerle

Hemmerle's modern identity can be traced to an unusual private commission during the 1990s.

According to CNA Luxury and Hemmerle's own history, third-generation jeweller **Stefan Hemmerle** encountered a collector whose taste leaned toward the austere black cast-iron jewellery associated with early 19th-century Berlin rather than overtly glittering pieces.

The resulting experiment paired a diamond with textured iron.

Instead of diminishing the gemstone, the dark material heightened its visual contrast. More importantly, it challenged the conventional relationship between the financial value of a gem and the metal surrounding it.

That experiment eventually became a philosophy.

Hemmerle now works with combinations that would look highly unusual on the specification sheet of a traditional high-jewellery maison: diamonds with iron, emeralds with bronze, gemstones surrounded by anodised aluminium, and precious materials alongside wood, pebbles or historical objects.

What appears inexpensive before it enters the workshop can emerge as the element that makes the entire jewel possible.

## Aluminium may be common. Working with it this way isn't.

Aluminium is perhaps the clearest illustration.

Today it is associated with everything from aircraft and electronics to packaging. Hemmerle, however, has used the lightweight metal as an artistic and engineering material in high jewellery.

Its **\[AL\] Project**, launched in 2016 following years of experimentation in its Munich workshop, consisted of more than 15 pairs of earrings and a brooch exploring aluminium through forms inspired by geometry, minimalism and nature.

Anodising allows the metal to take on intense colours, which gives a jeweller something conventional yellow gold cannot: a setting capable of visually echoing the colour of the gemstone itself.

A purple stone, for example, can sit inside a related shade of aluminium. The metal effectively retreats into the overall composition rather than announcing itself as a traditional gold setting.

Its low weight creates another advantage. Large earrings or dramatic jewellery can achieve substantial visual volume without becoming unbearably heavy.

But calling aluminium a “cheap” shortcut would badly misunderstand the process.

CNA reports that Hemmerle's aluminium components must be sculpted and carefully prepared before anodising, and the finishing process can be difficult to control. Some designs require stones to be positioned before the treatment, increasing technical complexity.

The raw material may be relatively ordinary.

The labour is not.

## Some Hemmerle jewels can consume more than 500 hours

This is where Hemmerle's definition of preciousness becomes easier to understand.

According to the company's official craftsmanship records, its jewellery is produced at its Munich atelier rather than outsourced. Individual creations can require **500 hours or more of work**, involving processes ranging from metalworking and patination to highly specialised stone setting.

Independent jewellery-industry interviews have reported the same extraordinarily time-intensive approach.

Christian Hemmerle has previously described years spent searching for precisely matched materials before work on certain creations can even begin, while experimental fabrication may involve repeated failures before a particular combination becomes technically feasible.

In other words, calculating a Hemmerle jewel solely by adding up the market price of its raw ingredients misses much of what is being sold.

The commodity value of a block of iron may be low.

The ability to transform that iron into an architecturally precise setting for an exceptional gemstone is scarce.

And scarcity, after all, has always been one of luxury's most powerful currencies.

## Before radical materials, Hemmerle made jewellery for royalty

The experimentation is particularly striking because Hemmerle did not begin as an anti-establishment contemporary design studio.

Its origins are firmly rooted in traditional European craftsmanship.

**Joseph and Anton Hemmerle established the house in Munich in 1893** after taking over a goldsmithing business specialising in medals and orders. Early clients included members of the Bavarian royal establishment, and Hemmerle says it was appointed a court supplier in the 1890s.

At the **1900 Paris Exposition Universelle**, the house exhibited an elaborate gemstone-and-enamel pectoral cross that received a prize.

That piece is not simply company folklore.

The **Metropolitan Museum of Art in New York** now holds the 1900 Hemmerle cross in its collection and confirms that it was created for the Paris exposition and recognised there.

That history matters because Hemmerle's modern experimentation was not a rejection of craftsmanship.

It was built upon it.

The family moved from medals, royal commissions and classical goldsmithing into jewellery that increasingly borrowed from architecture, modern art, geometric abstraction and unconventional materials.

## Even its most recognisable bracelet became a laboratory

One of Hemmerle's signatures is the open-ended **Harmony bangle**, first created in 1991.

Rather than treating that design as a formula to be repeated endlessly, Hemmerle has used it as a platform for material experiments.

Its archive documents versions combining diamonds with iron, precious metals with copper and other unconventional surfaces. Only a limited number are produced, and some techniques have required hundreds of hours of development.

That approach separates Hemmerle from the volume logic of much branded luxury.

A recognisable silhouette exists, but materials and execution can change dramatically from one jewel to another.

## Singapore has seen Hemmerle before

The September presentation is not the jeweller's first encounter with Singapore collectors.

In **2021**, Revival Jewels included Hemmerle in its *Modern Masters* exhibition alongside influential independent jewellers including JAR, Bhagat and Forms.

The Peak Singapore described Hemmerle then as a Munich house distinguished by sculptural designs and unconventional combinations of copper, bronze, aluminium, wood and less expected gemstones and materials.

Revival itself specialises in antique, vintage and collectible jewellery, with founder **Brenda Kang** sourcing pieces spanning numerous periods and jewellery traditions for collectors in Singapore and Southeast Asia.

That partnership makes sense.

Hemmerle frequently blurs the boundary between jewellery, decorative art and collectible object—territory increasingly familiar to buyers who collect across categories rather than following a single jewellery brand.

## Its pieces are entering museums as well as jewellery boxes

Another clue to Hemmerle's positioning is where some of its creations and historical works have ended up.

CNA notes that Hemmerle is represented in collections including the **Metropolitan Museum of Art**, London's **Victoria and Albert Museum**, **Cooper Hewitt, Smithsonian Design Museum**, and Munich's **Die Neue Sammlung**.

The Met's acquisition of its 1900 pectoral cross provides direct museum documentation of that historical legacy, while Die Neue Sammlung has also published material around Hemmerle and contemporary jewellery.

For collectors, that changes the frame.

A jewel is no longer assessed only as an accessory.

It can be approached like a piece of design.

Or sculpture.

Or an object connecting jewellery history with contemporary material experimentation.

## Why deliberately hide the value?

Traditional luxury often makes value visible.

Large diamonds sparkle.

Yellow gold signals immediately.

Platinum carries an established hierarchy.

Hemmerle frequently does the reverse.

A dark iron surface can suppress the visual prestige of the setting while making a diamond appear brighter. Bronze can add earthiness around an emerald. Aluminium can be coloured until it visually merges with a gemstone.

The result is a kind of luxury that may require explanation.

And that is precisely the point.

Christian and Yasmin Hemmerle told CNA that the house does not consider preciousness to reside exclusively in a material's market value. Instead, the worth of a finished creation can come from the combination of craftsmanship, creative thinking, technical difficulty, rarity and emotional meaning.

It is a philosophy particularly suited to collectors who no longer need a piece of jewellery to broadcast its cost from across a room.

## The newest generation isn't trying to copy the previous one

Hemmerle remains a family company.

**Christian Hemmerle and his wife Yasmin joined the business in 2006** and today run it with the continued involvement of his parents, Stefan and Sylveli.

What is striking is how they describe succession.

The goal is not to preserve every design decision made by an earlier generation. Instead, the family says it wants to retain the deeper principles—craftsmanship, curiosity, originality and integrity—while leaving room for the physical expression of those principles to evolve.

That distinction is important for any multi-generation luxury company.

Heritage can become either an asset or a cage.

Hemmerle's answer has been to make tradition the technical foundation, rather than the stylistic limitation.

## Even the Munich boutique reflects that thinking

The house recently moved after roughly **120 years at its former Munich address**, although it remained on Maximilianstrasse.

Its new space is at **Maximilianstrasse 30**, presented less as a traditional jewellery store than as a residential-style environment for private appointments. Hemmerle's website confirms the move and current address.

According to CNA, only around **15 to 20 jewels** may be displayed at one time, with additional pieces introduced after the house understands a visitor's interests.

Again, the emphasis is not volume.

It is discovery.

## So what are collectors actually paying for?

That may be the most interesting question raised by Hemmerle's Singapore appearance.

If jewellery value were determined only by the commodity price of the ingredients, an iron-and-diamond ring would be easy to calculate.

Diamond: expensive.

Iron: inexpensive.

Case closed.

But high jewellery has never really worked that way.

Provenance matters.

Design matters.

Rarity matters.

Skill matters.

Innovation matters.

And sometimes the material with the lowest price per kilogram is the very thing that makes the object impossible to reproduce.

Hemmerle's jewellery pushes that logic unusually far.

Its iron, bronze, aluminium and wood do not pretend to be precious metals. They remain visibly unconventional, sometimes deliberately understated, while serving as the technical and aesthetic counterpoint to gemstones of extraordinary quality.

### The Singapore test

From September 10 to 12, collectors in Singapore will have another opportunity to see that proposition at close range.

The jewels may contain diamonds, tourmalines, aquamarines and other exceptional stones.

But the most important material may be the one nobody traditionally considered precious.

Because Hemmerle's central argument after more than 130 years in business is surprisingly simple:

**Luxury does not necessarily begin with what a material costs.**

**Sometimes it begins with what almost nobody else knows how to do with it.**
