Recommended for those who like Cartier's Trinity ring. Although not visible, the inside is slightly scuffed and black, so it may have been worn. It was probably too small, as it hasn't been used much. It's stamped 925 on the inside, suggesting it's silver with gold plating. There are nuances in the different patterns of yellow gold and pink gold. A similar item was sold out on Amazon. ([Gorjana] gorjana Infinity Ring (mixed) 112-3016-M, Japanese size 11 / 16161 yen) It's difficult to determine the size because the rings are connected, but I measured it to be approximately size 11.
