Princess Cut Natural Diamond Engagement Rings in Platinum Under £4,000
27 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 princess cut is a square or near-square brilliant-cut diamond that offers exceptional sparkle in a modern, geometric profile. It retains more rough diamond weight during cutting than a round brilliant, making it a strong value proposition without sacrificing fire or brilliance.
Engagement rings with a 1ct natural diamond start from £3,379
Natural diamonds at 1ct are priced from £2,367 for the diamond alone. Combined with a setting, the total exceeds your £4,000 budget.
