All our jewels are accompanied by a Necklace size chart to avoid this kind of inconvenience to our customers. Our team has taken care to measure each article and to add the corresponding comment in each description. Therefore, the buyer assumes full responsibility for products that are too small / large. Nevertheless, we know that the purchase of such an item can cause great frustration.
Please feel free to contact our customer support by email at lsupport@nahyana.com: we will do our best to satisfy you (by offering a possible compensation, by example).
