This is a Japanese-made product, allowing for creation in other metals such as platinum, as we are producing a mold based on an artisan's original 18-karat gold frame design (design drawing available). The cameo is made of sardonyx (banded agate) with coloring, produced in Idar-Oberstein, Germany, renowned for its gemstone polishing. The cameo is machine-carved and measures approximately 3.5 cm. The carving, with its clear contrast, was purchased from Delgatto & Co. and was awarded "Excellent" during classification. The diamond quality is A-rank, 0.29 carats, suitable for pendants. The total weight is approximately 12.47g. We recommend this piece because the exquisite carving makes the portrait stand out even from a distance, undoubtedly enhancing your style.
