About this 1.51ct lab-grown asscher diamond

This 1.51ct lab-grown asscher sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG839633987 or 839633987. Listed at 7 retailers as of October 31, 2026, with prices from £363 to £1,358, a £996 spread on the same certified stone. Brilliant Earth lists it at £1,358. 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.
