B color, with case. These are not earrings, but natural pearl loose stones. They have some minor scratches and marks, and the shape is flat. If you are good at handicrafts, you can make them into earrings or studs, or use them for men's shirt cuffs. The size is about 3mm. Please refrain from purchasing if you are looking for perfection or are overly sensitive, as these are stored by a private individual and are materials for handmade crafts. Thank you for looking.
