June Birthstone Pearl Sterling Silver Necklace Designed by Amore Argento, The Vita Collection of Birthstones with Genuine Gemstones A gorgeous freshwater pearl is the centrepiece of this classic round necklace. Bringing elegant simplicity, the freshwater pearl is a symbol of harmony, purity and humility. Pearls are organic gems that grow within clams and other molluscs. Fresh water pearls are formed when a foreign object acts as an irritant inside the shell. Every piece of Amore Argento jewellery is perfectly presented in an attractive gift bag and box. Accompanied by the Amore heart-shaped microfibre polishing cloth, this is the gift that will always be treasured. This necklace is 6.5mm diameter with a 4mm round pearl.
