This 1ct lab-grown round sits in the classic one-carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG574347756 or 574347756. Listed at 19 retailers as of October 29, 2026, with prices from $206 to $1,135, a $929 spread on the same certified stone. MOH London lists it at $1,135. 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.
