Costco makes purchasing pearls simple and easy by offering the industry's highest quality pearls at the lowest possible price. As there is no standardised grading system for pearls, Costco does not list grades on our pearl items, however, all of our pearls are inspected by an independent Gemologist and your item is accompanied by an independent appraisal and valuation certificate guaranteeing the quality of your purchase. Costco is able to ensure that the pearls have no obvious blemishes, have good lustre and that the shape, colour and sizes of the pearls match where applicable. Whether you are looking for Akoya Cultured, Freshwater, South Sea or Tahitian, costco.co.uk has what you need.
