Its all down to purity. 10 carat gold is about 44% pure gold while 9 carat is slightly less. The purest gold is 24 carat which is 100% gold. Pure gold wears very quickly so most jewelry is mixed with harder wearing metals to create an alloy-so many parts gold to so many parts other metal.
There is more pure gold and less alloys, thus making it a higher carat. The higher the carat, the purer the gold.

24 carat jewellery is pure gold whilst 9 carat jewelery is not. It is still valuable just contains less gold. The advantage to 9ct jewelery is that it would be harder wearing.

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.
