Diamond Education

Knowledge is the ultimate luxury. Understanding your diamond ensures a choice that aligns with your values and your style.

What are Lab-Grown
& Mined Diamonds?

Can you tell the difference? Neither can a gemologist without specialized equipment.

The 4 C's

C1

Cut

The most critical factor. It determines how the diamond interacts with light. A well-cut diamond reflects light internally and disperses it through the top, creating that signature sparkle.

C2

Colour

Refers to the absence of colour. Graded from D (colourless) to Z (light yellow). We prioritise D-F (Colourless) and G-H (Near Colourless) for the purest ice-white aesthetic.

C3

Clarity

Measures internal inclusions and external blemishes. Flawless is rare. We curate diamonds that are "Eye Clean" (VS1-SI1), ensuring imperfections aren't visible to the naked eye.

C4

Carat

The physical weight of the diamond. While size matters, we believe it should never compromise the cut. A smaller, perfectly cut diamond will outshine a larger, dull one.

Certified
Excellence

IGI & GIA

Trust is paramount. That is why every Kitóko diamond (0.5ct+) comes with an independent grading report from either the International Gemological Institute (IGI) or the Gemological Institute of America (GIA).

These certificates are the blueprint of your stone, verifying its identity as lab-grown and rigorously grading its 4 C's. We do not self-certify. We rely on the world's strictest authorities to guarantee you get exactly what you pay for.
