About this 1.21ct natural heart diamond

This 1.21ct natural heart sits in the classic one-carat band, graded D colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6435427071. Listed at 7 retailers as of October 29, 2026, with prices from £2,975 to £5,721, a £2,746 spread on the same certified stone. NZ Jewellers lists it at £5,721. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
