Care & Composition

Care & Composition

Where is Kimaï jewelry made?

All of our jewelry is handmade in Antwerp, Belgium, by skilled artisans.

How is Kimaï jewelry made?

At Kimaï, all of our rings, necklaces, bracelets, and earrings are made with 100% recycled 18K solid gold and lab-grown diamonds.

Is all Kimaï jewelry made using 18k gold?

At Kimaï, our jewelry is always made using 18k solid gold.

How are Kimaï lab-grown diamonds made?

Visit ​Our Diamonds ​page to learn more about how Kimaï’s lab-grown diamonds are made.

What’s the difference between lab-grown and mined diamonds?

Kimaï diamonds are identical both chemically and physically to mined diamonds - the only difference is that they’re made in a lab. Grown using the same environment, the growing conditions have been engineered to produce an identical diamond without the social and environmental impact of mining.

Can I wear my Kimaï jewelry in water?

Yes! As all our pieces are made with 18K solid gold so there's no harm wearing them in water. Water will not damage the metal itself, but it can reduce the shine.

What does recycled gold mean?

​We use 100% recycled gold, derived from recycled 18K gold old jewelry.

Is recycled gold cheaper?

Recycled gold is not cheaper, as the price of gold is set based on market value.

Does 18k gold fade?

18K gold​ will not fade, as it is solid gold. However, 18K gold plated​ jewelry will​ fade over time, and affect the color of the jewelry. At Kimaï, we specifically use 18K ​solid​ gold to provide our clients with high quality pieces of jewelry that resist time, and can be passed onto generations.

How do you clean Kimaï's jewelry?

The easiest way to clean your Kimaï jewelry at home would be to fill a bowl with 2 cups warm water and several drops mild dish detergent. Soak your 18-karat gold jewelry in the solution for 15 minutes. Scrub the gold jewelry with a soft baby toothbrush or a cotton swab then rinse it with water.



Give it to me straight - are lab diamonds real diamonds?

Lab diamonds are real diamonds. Kimaï diamonds are identical in chemical composition to mined diamonds, only they’re made using solar energy in a lab. All that’s different between lab and mined diamonds is the impact our lab diamonds have socially and ecologically – which is significantly less.

How are Kimaï diamonds made?

Visit our diamonds to learn about the process.

Can you tell the difference between a lab grown diamond and mined diamond?

Lab grown diamonds are chemically and physically identical to mined diamonds - a gemologist wouldn't be able to tell them apart at a naked eye or even a microscope. Only specific machines can differ a lab grown diamond to a mined one.

Are lab grown diamonds GIA, HRD or IGI certified?

Yes, ​GIA, HRD, and IGI all grade lab grown diamonds. At Kimaï, we mostly use IGI grading reports but upon request we can get larger stones a GIA or HRD certificate. All our pieces that are above 0.5ct come with one of these certificates.

Do Lab created diamonds sparkle?

Lab diamonds do sparkle! As much as a mined diamonds. The sparkle of a diamond will always depends on the stone’s characteristics such as clarity, cut and polish, and lab diamonds are no different. Since the physical characteristics of a mined and lab diamond are not different, their sparkles isn’t different either!

Do Lab created diamonds have flaws?

Lab grown diamonds are grown the same way as mined diamonds (but in a lab!) - therefore they have flaws just like mined ones. Each one of Kimaï’s lab diamonds is unique and has its own characteristics.
