What does 18 carat gold mean?

18K gold is 75% pure gold. It's the ideal blend of precious metal content, color, luster, and hardness—perfect for high-quality jewelry with lasting value.

Which is better: 14K or 18K gold?

18K gold contains more pure gold than 14K, giving it a warmer, more refined appearance and being more hypoallergenic. 14K is slightly harder but less valuable. For engagement rings, 18K is the first choice in the luxury segment.

Are your diamonds certified?

Yes. All lab-grown diamonds at Ilikoez are certified by, for example, IGI or GIA. This guarantees the authenticity, quality, and traceability of each stone.
