This 1.27ct lab-grown heart sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG844677769 or 844677769. Listed at 13 retailers as of November 1, 2026, with prices from £198 to £1,162, a £964 spread on the same certified stone. Brilliant Earth lists it at £1,162. 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.
