Vintage 1960-1970s Watermelon Rivoli Rhinestone Cufflinks

These are truly spectacular Vintage cufflinks. I haven't tested them but I believe they are gold toned , with Watermelon Rivoli Rhinestones that really give that "WOW factor!! It is multi colored and just shines all those different colours when the light hits it from different angles. Even more spectacular in person!! Been in my family for over 50 years!!
