Genuine multi-colored crystals are then hand mounted in brass for strength and durability. Collar edges are cleaned, beveled and smoothed for that extra touch. Buckle and D-ring are made of solid brass, overlaid with an anti-rust chrome finish. • Medium: fits 16”-18.5"" neck • Large: fits 18”-21"" neck • X-Large: fits 21.5”-25"" neck"
