About this 3.06ct lab-grown radiant diamond

This 3.06ct lab-grown radiant sits in the three to five carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG549283378 or 549283378. Listed at 5 retailers as of November 4, 2026, with prices from £488 to £1,205, a £717 spread on the same certified stone. MOH London lists it at £1,205. 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.
