About this 1ct lab-grown round diamond

This 1ct lab-grown round sits in the classic one-carat band, graded G colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG817634432 or 817634432. Listed at 17 retailers as of October 26, 2026, with prices from $363 to $1,471, a $1,108 spread on the same certified stone. MOH London lists it at $1,471. 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.
