Measurements (laid flat) Large pearl: 54cm Small pearl: 41.5cm Please note that there may be slight variations due to amateur measurements. The large pearl necklace also includes medium-sized pearls. The small pearl necklace has uniformly sized pearls. I purchased these about 5 years ago for a wedding, but I never used them. They are unused but have been stored for a long time. Please consider purchasing if you don't mind this.
