A 100g jewelry weighing scale is a specialized precision instrument designed for accurately measuring small quantities of valuable materials like gold, silver, diamonds, gemstones, and other precious metals. Its primary application lies within the jewelry industry, catering to jewelers, goldsmiths, gemstone dealers, and even pawn shops. The core purpose of a 100g jewelry scale is to provide highly precise measurements, typically with an accuracy down to 0.001g (1mg). This level of precision is vital for determining the true value of precious items, as even minute differences in weight can significantly impact their price.
