About this 1.28ct lab-grown oval diamond

This 1.28ct lab-grown oval sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and VS2 clarity (very-slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 5503647550. Listed at 15 retailers as of October 29, 2026, with prices from £490 to £1,455, a £965 spread on the same certified stone. MOH London lists it at £1,455. 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.
