From rough to refined, since 1980.
Who we are
Four generations of craftsmanship, straight from the heart of Amsterdam
Diamonds & Jewels Amsterdam is part of Diamond Factory Koh-I-Noor, an Amsterdam family business with deep roots in the city — it began in the Jordaan, located on the iconic Muntplein.
Since 1980, we have been cutting, designing, and selling natural diamonds and handmade jewelry. What began with the passion of founder Dirk, who learned the craft at the age of 17, has now grown into a fully-fledged diamond cutting and jewelry store with four generations of expertise.
With us, you're not just buying a piece of jewelry—you're investing in a story, craftsmanship, and lasting beauty. Whether you order online or visit our store, we ensure a personal and reliable experience.
Handmade in
Real diamonds, honestly cut
Our diamonds are 100% natural, conflict-free, and handcrafted in our own cutting facility. Certified, inspected, and transparent.
Sustainable gold, timeless design
We work exclusively with real gold: yellow, white, or rose gold that doesn't tarnish. Combine this with modern or classic styles – for a piece of jewelry that will last for generations.
Personal service
Whether you shop through our website or visit us at Muntplein, you'll receive the same personal attention, honest advice, and expertise. That's our promise.
Our mission
Our mission is to make the beauty and power of real diamonds accessible to everyone—with sustainable materials, transparent pricing, and genuine service. From our own cutting facility, we bring the entire process together: from raw crystal to sparkling finish.
Because a diamond isn't a trend. It's a story. And that starts with us.
What our customers say
Skilled staff, pleasant and friendly approach, ultimately succeeded in finding an engagement ring quite quickly. My girlfriend (now fiancé!) is also very happy with it.
I previously visited the physical store in Amsterdam, and now I have a ring custom-made online with the same attention to detail and quality. Emails are answered very quickly and with a personal touch. Kudos!
Fast and free delivery! They delivered it personally because I lived near Amsterdam, reliable people. My wife is also very happy, highly recommended!
