About this 0.93ct lab-grown round diamond

This 0.93ct lab-grown round sits in the just-under-one-carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG510158226 or 510158226. Listed at 9 retailers as of October 26, 2026, with prices from £94 to £602, a £508 spread on the same certified stone. MOH London lists it at £602. 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.
