K18 Rare Inlay Mosaic Opal Necklace Top This is an attractive pendant top with an artistic K18 art design for collectors. Chains and earrings are not included. Please refer to the image for reference. This opal displays a vibrant red play-of-color (red flash). The red color, which flickers like flames, is particularly rare among opals, and you can enjoy a variety of expressions depending on how the light hits it. Mosaic opals are highly valued in the jewelry industry for their unique beauty and rarity. Mosaic opals are formed by combining small pieces of multiple opals to create a pattern, and the variations in color and pattern are very diverse as natural materials. Therefore, even with the same design, each one is unique, and the (inlay) technique is used, and the number of craftsmen who can do it is limited, making mass production difficult. In addition, it is mined only in specific areas of Australia, so the supply is limited, and its rarity is increasing. For these reasons, K18 gold pendant tops using mosaic opals are more expensive than other common jewelry and are popular as special gifts and collection items. With its beautiful brilliance and rarity, it can be said that owning it is a piece of jewelry that has a special meaning in itself. 【Size】 (approx.) 3cm including the bale K18 stamp Opal part: Made in Australia Please refer to the photos.
