This is an 18k gold brooch with coral, said to have been made by my aunt. It seems she only looked at it and touched it, but never wore it. Please see photo 9 for the 18k hallmark. I apologize for the poor quality of the photos. The variations in color and the natural small holes (photos 19 and 20), and blurriness of the natural coral make this brooch endearing. The motif is like a 'chrysanthemum' or a 'peony', but it doesn't feel old-fashioned or Japanese. It has a stylish carving. The use of 18k gold on the back is not a solid design, but rather a detailed one with a beautiful pattern. The coral is attached with eight 18k gold prongs. A gentle, beautiful world spreads within the coral, which is approximately 5cm x 3cm. There may be small natural "chips," but it appears there are no large scratches or "chips." Please forgive me if I have overlooked anything. As shown in photo 14, there are two holes in the box to secure the brooch, but they are stiff, so I think it's best not to use them. I am very sorry, but due to the high value of this item, returns are not accepted. I look forward to hearing from those who understand that this item has been stored at home.
