About this 2.91ct lab-grown round diamond

This 2.91ct lab-grown round sits in the two to three carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG607309941 or 607309941. Listed at 11 retailers as of October 31, 2026, with prices from $625 to $1,988, a $1,363 spread on the same certified stone. MOH London lists it at $1,988. 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.
