About this 1.01ct natural heart diamond

This 1.01ct natural heart sits in the classic one-carat band, graded K colour (faint-tinted) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1568579867. Listed at 17 retailers as of November 5, 2026, with prices from £726 to £2,389, a £1,663 spread on the same certified stone. NZ Jewellers lists it at £2,389. 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.
