The product is a real freshwater pearl. Size is 8 mm. Their shapes vary because they are natural. We match the ones closest to each other and send them. If you want the product you buy to be perfect in shape, we recommend that you buy fake fabricated products, not real pearls, because real pearls are rarely perfect. The nail used and the back closure clip are silver plated on metal. Do not allow chemicals such as perfume, disinfectant etc. to come into direct contact with the earring. Colour, size, shape and shine are the main factors that determine the value of the pearl. The value of a pearl is measured by its unique properties as well as its natural shine. Storing pearls in safes and closed places for a long time causes them to fade and become dull. For this reason, it is recommended that you wear your pearls frequently. Frequently used pearls are allowed to renew themselves by taking air. Recommended for storing pearls are tulle pouches and soft velvet pouches that do not have any glitter on them. Pearls must be ventilated while being stored. Pearl can be wiped with a soft and slightly damp cloth after use. If you think that the color tones of the product sent do not match each other, you can change the product by contacting us. Customer satisfaction is important to us.
