24 karat Gold is pure, with no alloy blend. Each pack of leaf contains 20 books. Each book contains 25 lvs, with a total of 500 leaves. Each leaf is 3 3/8" x 3 3/8" square. Approx. coverage is 39 sqft. We offer a ariety of gram weights to suit the needs of your specific project. Gram weight is determined by the weight of 1000 leaves of 3 3/8 inch square gold leaf. This relates more to 'density' of leaf rather than thickness. Each leaf is beaten to approx. 0.5 microns thick. Whether you purchase European gold leaf or Chinese, the size (3 3/8" sqre) and thickness (0.5 microns) is standard. The wieght changes by the amount of gold content per leaf. So a Chinese 24 kt gold leaf weighs 16 grams per 1000 lvs, and is therefore less dense than an Italin gold leaf, weighing 18 grams. The European leaf will be firmer, is less likely to tear and may show less wrinlkling in the final product (depending on your gilding technique).
