I am very sad to let go of these wonderful earrings, which I purchased here, as they don't suit me. Below is the previous seller's comment: ＝＝ British European Antique K9 Earrings, Made in England These are antique triplet opal earrings from England. 【Size】 Approx. 1.8cm 375/k9 British hallmark 9CT 【Description/Condition】 These earrings are made using the traditional Victorian method and are quite rare, being antique earrings made in England. I would like to sell them to someone who will cherish them. Please take a good look at the photos and consider purchasing them. They are elegant and have a gold frame reminiscent of European art, making them antique jewelry with a mature atmosphere. I purchased them at an antique show a while ago. Although it is faded, 9CT means k9. This is a sign of old British antique jewelry. It is a rare item, and there are no loose screws or damaged parts, so you can use them. Although they are inferior to natural opals, the triplet opals have a brilliant shine that is not inferior, and the play of color changes depending on the angle. Although the gemstones are light and the material is inferior, k9 antique British jewelry is expensive because of the manufacturing process, the design, and the rarity that cannot be obtained today. Please refrain from purchasing if you prioritize the quality of the loose stones and materials. Please trade as antique items. They are items that can be worn elegantly, and they have a beautiful shine and presence. ○ What is a triplet? ... It is an original cut stone made by laminating white labradorite, a thin sheet of shell, and malachite in three layers and coating them. ◯ The blue box is not included, but a black box will be provided instead.
