This black rutilated quartz center stone sits on an angular rose gold band. Small clusters of diamonds add a small bridal touch to this edgy engagement ring. More diamonds does not essentially make a hoop look too over-the-top. This vintage-inspired Etsy engagement ring has seven diamonds, but it still appears dainty. Set on a yellow gold band, it features a marquise-cut middle stone flanked by two small round-cut diamonds and an east-west set marquise stone on both sides.
