Think it means that it is gold plated - with 18carat gold. No idea what the inside will have been made of though
It probably means that the ring is 18 karat gold electroplated, not solid gold.
nine 24th of the weight. Pure gold is 24 carat. The dilution through the addition of base metals makes the gold more hard wearing but reduces the cost. If the ring weighs 24 grammes only 9 grammes will be gold. The rest will be base metals. In an 18 carat ring weighing 24 grammes 18 grammes will be gold.
there are 24 parts that make up pure gold. so 9 carats is 9 parts gold and 15 parts of another material so 9 parts gold to 24 parts is 37.5% gold. were 18 carat is 18 parts gold to 24 parts of another material or 75% gold. thus the difference is in the amount of gold in the ring. there is also a difference in the color of the gold pieces. the 9 carat gold is lighter than the 18 carat.
A ring with an "18K" hallmark typically means it's solid 18K, but you can't rely on that. Hallmarks (stamps) are often wrong.

Area of bullseye 102 ie 100pi; Area of inner ring and bullseye together is 252 ie 625pi, so area of inner ring is 525pi. Area of second ring and its contents is 402 ie 1600pi, contents area 625pi so area of second ring 975pi. Area of third ring and contents is 552 ie 3025pi, contents area is 1600pi so area of third ring is 1425pi Area of outer ring and contents is 702 ie 4900pi, contents area is 3025pi so area of outer ring is 1875pi. I note that for the three outer rings the area increases by 450pi each time, but for the inner ring it only increases by 425pi. What the reason for this is, I know not unless I've miscalculated somewhere...
