About this 4.02ct lab-grown round diamond

This 4.02ct 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 LG607347257 or 607347257. Listed at 6 retailers as of November 1, 2026, with prices from $931 to $2,752, a $1,821 spread on the same certified stone. MOH London lists it at $2,752. 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.
