About this 1.05ct lab-grown round diamond

This 1.05ct lab-grown round sits in the classic one-carat band, graded K colour (faint-tinted) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG811646379 or 811646379. Listed at 12 retailers as of November 2, 2026, with prices from £116 to £674, a £558 spread on the same certified stone. MOH London lists it at £674. 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.
