Circa 1970-80s, 18k, by Trudel, Zurich, Switzerland. This spectacular one-of-a-kind ring designed by Kurt Aepli for Trudel is set with 4.20 carats of superb white diamonds (F color, VS clarity). The look is understated posh (the Swiss sweet spot!!). Some pieces of jewelry start conversations, invite smiles, and ultimately become a part of your signature style; this Swiss-modern jewel is all that. Excellent condition.
