This 1.29ct natural heart sits in the one-and-a-quarter to one-and-a-half carat band, graded F 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 5232743920. Listed at 3 retailers as of November 4, 2026, with prices from £2,181 to £3,567, a £1,386 spread on the same certified stone. MOH London lists it at £3,567. 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.
