These are Akoya pearl earrings that I previously purchased here. I loved them when I bought them, but I'm selling them because I have too many similar ones. Photos 1-2 are taken by me, and photos 3-4 are borrowed from the seller. From the purchase site: These are Akoya pearls processed in Kobe, the city of pearls. They are a natural, gentle color, not dyed. There are small blemishes, so they are priced accordingly. They are not noticeable when worn, but please understand this before purchasing. In the photos, the interference color (the color when light hits them) appears strongly blue, but they are white-based to the naked eye. They have an aurora interference color and are beautiful ^-^ ◉ Akoya Genuine Pearl Single Stud Earrings Material: Surgical stainless steel Pearl size: Approximately 9.5mm Color: Natural (slightly bluish) Shape: Semi-baroque Retail price: ¥6400 Pearls are formed by chance in nature, and each one has a different color and shape, and may have growth marks or blemishes. The fact that no two pearls are exactly alike is a major attraction of pearls and proof of their authenticity. Please purchase only if you understand this.
