Cushion Cut Natural Diamond Side Stone Engagement Rings in Platinum Under £4,000
2 handcrafted designs · Hatton Garden, London
Platinum and natural diamond is the most traditional luxury engagement ring pairing. Both are rare, enduring, and increase in beauty over time. This combination is the choice of heritage jewellery houses and has graced the most celebrated engagement rings in history.
The cushion cut features softly rounded corners and larger facets that produce broad flashes of light rather than the pinpoint sparkle of a round brilliant. Its pillow-like shape evokes romance and vintage elegance, making it a favourite for those who appreciate character over pure brilliance. Available in square and elongated proportions.
