MiJu takes pride in partnering with a single, trusted lab-grown diamond supplier and a single, trusted natural diamond supplier


Laboratory Grown Diamond

Laboratory-grown rough diamonds are meticulously cultivated within controlled laboratory environments that perfectly mimic the conditions in which mined diamonds naturally form deep below the earth's surface.

At the heart of diamonds lies carbon as the key molecular component. Utilizing a diamond seed and an external carbon source, laboratory-grown diamonds are cultivated atom-by-atom and layer-by-layer under intense pressures and temperatures.

Subsequently, these laboratory-grown rough diamonds undergo the same cutting and polishing processes as all other diamonds.


Natural Diamond

We take pride in our collaboration with a single, trusted natural diamond supplier based in the Netherlands, with over 20 years of experience in the industry.

In adherence to our commitment to conflict-free diamonds, our supplier strictly follows the Kimberley Process's stringent standards.

The Kimberley Process (KP) is an international initiative that eliminates the trade of conflict diamonds, ensuring transparency and oversight in the diamond industry. This commitment guarantees the ethical integrity of our diamonds

Diamond Grading

IGI Certificate

Our lab-grown and natural diamonds of 0.5ct and higher are accompanied by full grading reports from the International Gemological Institute (IGI), one of the world’s leading gemological laboratories.


The 4 C's
The quality of a diamond is determined by the 4 C's: Cut, Color, Clarity and Carat.

The diamond's Cut determines its sparkle, with cutting precision and perfect proportions creating its brilliance. Suboptimal cutting factors can adversely affect the diamond's appearance.

Color refers to the diamond's shade, with the most valuable and rare diamonds falling within the colorless range of D, E, and F.

Clarity refers to the number of inclusions in the stone, with higher quality diamonds possessing fewer inclusions.

Carat measures the diamond's weight and size.
