Every piece is handmade from real freshwater pearls. Jewellery that are perfect for everyday wear. FRESHWATER/CULTURED PEARLS - Freshwater mollusks are nucleated by creating a small incision in the fleshy mantle tissue of a 6 to 12 month old mussel, then inserting a 3mm square piece of mantle tissue from a donor mussel. The mollusks are then returned to their freshwater environment where they are tended for 2-6 years. They are available in many different shapes and sizes and have a tremendous range of colour.
