Yes, Orchira use only 100% authentic cultured pearls and natural gemstones. OOrchira jewellery only selects the top 5-10% harvest of freshwater pearls grown from mantle tissue, not solid bead nuclei. As all Orchira’s pearls are grown from natural oysters, they are not man-made, so a certain amount of natural blemishes is normal and should be tolerated for naturally formed gems.
