About this 3ct lab-grown round diamond

This 3ct lab-grown round sits in the three to five carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG476186487 or 476186487. Listed at 11 retailers as of November 5, 2026, with prices from $2,989 to $25,820, a $22,832 spread on the same certified stone. MOH London lists it at $25,820. 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.
