This is a gorgeous, stunning statement ring from an estate collection. It's a vintage piece from the early 1990s. It features a large, emerald-cut blue topaz gemstone, accented with square-cut marcasites for some added subtle sparkle. The ring is sterling silver. It's stamped 925, and signed "A" and "Thailand," but I'm unable to identify the maker. It weighs 4.9g. The ring is a size 8, and it's in excellent condition. It's been gently cleaned and sanitized to bring out its original sparkle. It will come in a gift box.
