About this 1.61ct lab-grown round diamond

This 1.61ct lab-grown round sits in the one-and-a-half to two carat band, graded E colour (colourless) and I1 clarity (included), with a very-good cut grade and certified by IGI LG754510415 or 754510415. Listed at 10 retailers as of October 29, 2026, with prices from £141 to £825, a £684 spread on the same certified stone. MOH London lists it at £825. 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.
