About this 10.03ct lab-grown round diamond

This 10.03ct lab-grown round sits in the over five carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG839647755 or 839647755. Listed at 19 retailers as of October 26, 2026, with prices from £1,252 to £7,004, a £5,752 spread on the same certified stone. With Clarity lists it at £7,004. 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.
