The cheaper one is k9 which contains 375/1000 pure gold while k14 contains 585/1000 pure gold and k18 750/1000. Another difference that affects the price is that k18 is much heavier than k9 due to the specific gravity of gold. That is why k18 is much more expensive as it's heavier and contains more pure gold. As 18k contains more pure gold (750/1000) it has a more vivid Yellow color compared to 9k and although the difference is slight to be recognized from a display it exists. In the other gold colors (white-rose) we can have the same result with 9k or 14k due to special alloys for jewelry (always nickel-free).Centrally located in the heart of Athens-Greece, for over 15 years, and been respected for honesty, quality, and design, our on-line shop came as a normal evolution.
