18k is the metal purity (18/24k which is 75%) EF is probably the manufacturer's or designer's mark.
its only 18k gold plated, not full gold This could be incorrect. If the ring has 18K/PLAT then the ring is 18K gold with some platinum. Probably to hold the diamond.
Not enhanced in terms of pearls
LSC is the maker and 950PT stands for 95% Platinum not 18K gold.

The cost of a 0.25 carat diamond ring in 18k white gold can vary widely depending on the quality of the diamond and the intricacy of the ring design. The weight of the ring setting at 4.5 grams may affect the price slightly due to the amount of gold used. It is best to consult a jeweler for an accurate price estimate based on your specific preferences and budget.
ring found in pawn shop since 1994,ring is 18k gold diamond encrusted...will consider best offer.
Better to lose a 9k gold ring than a 18k one ! 18k is purer gold than 9k.
This means that the ring is matt gold electroplated. The 18k is the amount of gold that is found in the ring.
The weight and purity are not related. A karat is a measure of purity when talking about gold, while a karat for a diamond is dependent on size so if the 10K and the 18K rings are approximately the same size, I would say that the 18K is heavier
About 1/20th the price of solid 18k.
The value of a diamond depends on its cut, its clarity, its colour and its carat weight. A local jeweler can give you the answer you want.
