Overview of Iko Sapphire Diamond Cookware

Iko burst onto the scene in 2020 with their unique diamond-reinforced ceramic nonstick pans.

The company set out to create the most durable and longest-lasting nonstick cookware ever. Here are the key features and technologies:

  • Diamond-infused ceramic nonstick – Tiny diamond particles are infused into the PFOA-free ceramic coating. This dramatically strengthens the nonstick surface to prevent scratches.
  • Aluminum core – An aluminum core is layered between the nonstick interior and brushed stainless exterior. This allows for quick, even heating.
  • Brushed stainless exterior – The outside is made of stainless steel for durability, easy cleaning, and a sleek look.
  • Riveted handles – Secure stainless steel handles stay cool on the stovetop. Silicone-coated helper handles provide extra grip.
  • Vented glass lids – The included tempered glass lids have steam vent holes for visibility and heat control.
  • Oven safe to 450°F – You can safely use Iko pans in the oven or broiler up to 450°F.

With this innovative construction, Iko claims to offer the convenience of nonstick along with the durability and versatility of stainless steel. A bold promise that required thorough testing…

Testing the Iko Diamond Cookware

I acquired a 10-piece Iko Sapphire Diamond set with pots, pans, and lids to put through a battery of cooking tests.

Over the course of 3 months, I used these pans to cook at least 5 days a week, often daily. Here are some of the ways I tested performance:

  • Browning and searing – Beef, pork, chicken, and fish. Checked fond development and caramelization.
  • Frying and sautéing – Onions, veggies, eggs. Evaluated nonstick release and ease of tossing and flipping food.
  • Simmering and boiling – Soups, stews, pasta. Assessed even heat distribution.
  • Baking – Cookies, frittatas, casseroles up to 400°F oven temp.
  • Broiling – Meat and veggies under high heat broiler.
  • Eggs – Fried, scrambled, omelets. Such a good nonstick test!
  • Pancakes – Flipping delicate pancakes reveals lots about the nonstick quality.
  • Fish – Healthy fats in fish stick fast if the nonstick isn’t good.
  • Tomato sauce – The acidity reveals wear and tear on the cooking surface.

In addition to cooking performance, I evaluated:

  • Durability – Used metal utensils for all cooking tasks to test scratch resistance.
  • Cleaning – Washed by hand to determine effort required.
  • Handles – Assessed comfort and whether they stayed cool during stovetop cooking.
  • Lids – Checked the fit and seal of the included glass lids.

After this extensive testing, I feel confident in the performance capabilities of Iko Diamond cookware. Keep reading for the results…

Key Features and Benefits

Here are the standout features and benefits I found using the Iko Sapphire Diamond cookware:

1. Extreme Durability

The diamond-infused ceramic coating lived up to its reputation for durability. Metal utensils had zero effect during months of cooking and stirring. I tried to scratch the surface with a fork – no luck. It remains smooth as the day I got it.

Ceramic nonstick pans have a reputation for wearing out quickly. But Iko’s diamond reinforcement makes this the most resilient nonstick cookware I’ve ever used.

For home cooks who are tough on their pans, Iko offers peace of mind that the nonstick surface can withstand years of regular use.

2. Effortless Nonstick Cooking

In terms of nonstick performance, this cookware is top-notch. Food released cleanly with little or no oil needed during cooking.

Delicate foods like eggs and fish came off the pan perfectly intact. And the nonstick quality didn’t degrade over time. Even after daily use, food continued sliding off just like a well-seasoned cast iron skillet.

The diamond-infused ceramic coating delivered outstanding nonstick ability for all my cooking tests.

3. Even Heating and Control

The aluminum core allowed the Iko pans to heat up quickly and evenly. No frustrating hot spots or cold zones.

The smooth, gradual heating enabled good browning and searing without food sticking or scorching. Perfect for finicky foods like eggs or fish.

Once heated, the pans maintain temperature nicely allowing you to dial in the ideal heat for simmering sauces or frying without burning.

4. Quality Construction

The Iko pans have a substantial weight in hand compared to typical lightweight ceramic cookware. The brushed stainless steel exterior looks classy and makes the pans highly durable.

The handles are securely riveted and stay cool on the stovetop. And the included glass lids fit tightly to seal in heat and moisture.

There are no signs of wear and tear after months of frequent use. The construction quality ensures these pans will last for many years.

5. Versatile Performance

I used the Iko pans for pretty much every home cooking task imaginable – searing, frying, boiling, baking up to 450°F.

The diamond ceramic coating worked flawlessly no matter what I threw at it. The versatility of this cookware makes it an excellent all-around choice.

For home cooks who want one set of durable, high-performing pans to use for all their cooking, Iko delivers.
