About this 4.01ct lab-grown round diamond

This 4.01ct lab-grown round sits in the three to five carat band, graded J colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG607347275 or 607347275. Listed at 7 retailers as of October 29, 2026, with prices from $928 to $2,760, a $1,832 spread on the same certified stone. MOH London lists it at $2,760. 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.
