About this 1ct natural heart diamond

This 1ct natural heart sits in the classic one-carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6205114896. Listed at 22 retailers as of November 5, 2026, with prices from £2,168 to £5,286, a £3,118 spread on the same certified stone. NZ Jewellers lists it at £5,286. 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.
