A diamond ring marked with "18ksp" typically indicates that the ring is made of 18-karat gold, with "sp" possibly signifying "semi-pure" or a specific alloy used in its composition. This marking suggests that the gold content is 75% pure, with the remaining 25% consisting of other metals to enhance durability and color. It's important to verify the authenticity of the marking through a reputable jeweler, as variations in markings can occur.
