Jewelry marked "1-30 10K" indicates that the piece contains 10 karat gold, which means it is made up of 41.7% gold and 58.3% other metals. The "1-30" likely refers to the manufacturer's specific mark or code, which can denote the jeweler or the location of production. This marking helps verify the gold content and authenticity of the piece.
