About this 1.33ct lab-grown heart diamond

This 1.33ct lab-grown heart sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1528277900. Listed at 10 retailers as of November 3, 2026, with prices from £521 to £2,501, a £1,980 spread on the same certified stone. MOH London lists it at £2,501. 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.
