Swiss Diamond history: diamond non-stick and premium steel, from Sierre, Switzerland
A Swiss coating lab founded in 1974 learned to lock real diamond crystals into a non-stick surface. Today Swiss Diamond pairs that technology with 18/10 stainless steel cookware.
What is Swiss Diamond cookware?
Swiss Diamond is a Swiss cookware brand known for non-stick pans with a coating reinforced by real diamond crystals, and for 18/10 stainless steel lines such as Premium Steel DLX. Its roots go back to a coating lab founded in Sierre, Switzerland, in 1974, and it says all of its cookware is made in Switzerland at the HORT Coating Center in Sierre.
Why can you trust Swiss Diamond when you buy cookware?
A pan is a daily tool, so you want evidence behind the promises. Swiss Diamond’s record can be checked on five points.
More than 50 years of coating science
The diamond-reinforced idea came out of HORT Coating Center, a Swiss company founded in 1974. Research on an advanced non-stick began in 1998, and Swiss Diamond has sold cookware since 2001.
Research and production kept in-house
Swiss Diamond says its coating is developed and applied in-house using plasma technology, and that research and production are managed by the company and never outsourced. That control is what keeps quality consistent.
Made in a named Swiss factory
Swiss Diamond says its cookware is manufactured in Sierre, Switzerland, at the HORT Coating Center. A named site and a clear address are easier to verify than a vague origin claim.
Premium stainless steel, not just non-stick
For cooks who prefer steel, Swiss Diamond offers 18/10 Premium Steel DLX and five-layer Premium Clad. The range lets you choose non-stick for delicate foods and steel for searing.
Responsible production
Swiss Diamond says its cast aluminium bodies are pressure-cast from 100% recycled aluminium and that its facility is powered by hydroelectric energy. Its CXD ceramic line is made without intentionally added PFAS.
Where is Swiss Diamond made? The factory in Sierre, Switzerland
Sierre is a town in the Swiss canton of Valais, in the Alps. It is home to HORT Coating Center SA, the Swiss company that co-founded the diamond-reinforced coating idea in 1974 and is today the exclusive manufacturing center for Swiss Diamond cookware.
In 2006 Swiss Diamond International spun off HORT Coating Center and focused on worldwide marketing and sales. In 2008 the coating center invested in a high-pressure aluminium foundry and doubled its coating lines, so the aluminium bodies and the coating are now made on the same site.
Some retailer listings describe certain stainless steel lines, such as Nonstick Clad, as made elsewhere. Swiss Diamond states that all of its cookware is made in Switzerland, so check the product page for the exact item you are buying.
How a Swiss Diamond non-stick pan is made
-
Materials arrive. Diamond powder and the custom non-stick components are delivered to the Sierre factory.
-
The body is cast. Recycled aluminium is pressure-cast into a heavy, flat pan body that resists warping.
-
The coating is applied. Real diamond crystals and the non-stick composite are applied in-house with advanced plasma technology.
-
The finished pan is checked. Production and finishing take place in a controlled, precision-driven facility.
Swiss Diamond non-stick: how the diamond coating works
In the 1990s Swiss Diamond found that diamonds could change how non-stick coatings last. Its engineers in Sierre developed a method to combine genuine diamond crystals with a high-quality non-stick composite. The brand says each pan contains up to 200,000 crystals, which reinforce the surface so it stays slick for longer.
The result is the XD line, and its latest form, XD+, uses a diamond-reinforced PTFE-based coating. Select XD+ pieces come in induction-ready versions. CXD is the ceramic alternative: a dual-layer, diamond-reinforced ceramic non-stick made without intentionally added PFAS and suitable for induction.
The pans are built on pressure-cast aluminium with a perfectly flat base, which distributes heat evenly and is designed not to warp. Retailer listings cite oven safety up to 500 °F (260 °C). Always check care instructions for your line.
Swiss Diamond Premium Steel: 18/10 stainless steel cookware
Swiss Diamond’s steel lines give cooks a durable, non-coated option for searing, sautéing and sauces. Premium Steel DLX is the practical choice, while Premium Clad and Prestige Clad step up the construction.
Premium Steel DLX is crafted from 18/10 stainless steel, with roughly 18% chromium and 10% nickel for rust resistance and a lasting finish. It is induction-ready, with an encapsulated, impact-bonded base of aluminium and an induction plate that spreads heat evenly. Riveted stainless handles, tempered glass lids with a vent and a mirror finish complete the range.
Swiss Diamond describes it as durable stainless essentials at practical prices, with reliable performance without multi-ply pricing. A retailer listing cites oven safety up to 500 °F (260 °C) and a limited lifetime warranty on all Premium Steel products; confirm current terms with the brand.
Premium Clad is built from five bonded layers of stainless steel with a satin polished finish, so heat spreads evenly up the sides as well as across the base for golden sears and smooth sautés. It suits gas, electric and induction.
| Line | Construction | Finish and features | Best for |
|---|---|---|---|
| Premium Steel DLX | 18/10 stainless steel with encapsulated aluminium and induction-plate base | Mirror finish, riveted handles, tempered glass lid | Everyday cooking at a practical price |
| Premium Clad | Five-layer bonded stainless steel | Satin polished finish, ergonomic handles, oven safe to 500 °F | Searing and even heat up the sides |
| Prestige Clad | Clad stainless steel | Upper tier of the steel range | Cooks who want a step up in construction |
| Nonstick Clad | XD diamond coating on stainless steel | Induction compatible | Steel build with non-stick release |
Why Swiss Diamond is one of the most innovative cookware brands
Swiss Diamond’s innovation comes from materials science: it took a coating idea from a Swiss lab and kept improving it, while extending the same quality thinking to steel.
Diamonds in the coating1990s
Swiss Diamond discovered the potential of diamonds to transform non-stick performance, leading to the XD coating reinforced with real diamond crystals.
A dedicated research programme1998
As demand for premium cookware grew, Swiss Diamond began research into an advanced non-stick coating in its Sierre laboratory.
In-house plasma applicationProduction method
The coating is developed and applied in-house with advanced plasma technology, a level of process control many cookware brands do not keep in-house.
A foundry next to the coating lines2008
HORT Coating Center acquired a state-of-the-art high-pressure aluminium foundry and doubled its coating lines, bringing body and coating production together.
Induction-ready non-stickXD+ and CXD
Select XD+ pieces and the whole CXD line are induction-ready, bringing diamond non-stick to modern hobs.
Ceramic non-stick without added PFASCXD
CXD combines a dual-layer ceramic non-stick with diamond reinforcement and is made without intentionally added PFAS, developed and manufactured in Switzerland.
Steel for every budgetPremium Steel and Clad lines
From Premium Steel DLX to five-layer Premium Clad, Swiss Diamond offers stainless steel that suits both value and performance priorities.
