About this 1.81ct natural heart diamond

This 1.81ct natural heart sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI 812602630. Listed at 12 retailers as of November 5, 2026, with prices from £4,034 to £9,005, a £4,971 spread on the same certified stone. NZ Jewellers lists it at £9,005. 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.
