About this 1.51ct lab-grown oval diamond

This 1.51ct lab-grown oval sits in the one-and-a-half to two carat band, graded H colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG675599627 or 675599627. Listed at 4 retailers as of October 31, 2026, with prices from £356 to £754, a £398 spread on the same certified stone. Brilliant Earth lists it at £754. 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.
