It depends on the size of the ring, the larger the ring is, the more gold it takes to make it so the more expensive the ring becomes. Also, the thickness plays a major part too, a small, thin band of gold isn't as expensive as a large, thick band of gold.
8ct and 7ct are a pre-1950 common purity of gold in jewelry and watches. It is 8/24 pure or 7/24 pure and is typically the lowest accepted grade of gold. Most modern acid tests will not read this level of gold as they usually only go as low as 10k
333 parts of 1000 It means the gold content is one third of the total content.
It typically means two things. First, the ring was probably made before the stamp act of 1906 which regulated, among other things, what jewelers could and couldn't hallmark on their wares. Second, assuming the piece is US made, it would mean the ring is of at least (and quite likely) 10k gold. This standard has long been the minimum standard considered as "solid gold" in the States. The UK has a lover 9ct standard and some European countries (ie Italy) had 8ct up until the 1990s when they standardized their marking system. Pete
If you go to the store or site of Party city.com the splashy star stickers are 0.99 for 8ct.
