About this 1ct lab-grown round diamond

This 1ct lab-grown round sits in the classic one-carat band, graded J colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a standard cut grade and certified by IGI LG389979971 or 389979971. Listed at 13 retailers as of October 29, 2026, with prices from $1,118 to $7,614, a $6,496 spread on the same certified stone. MOH London lists it at $7,614. 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.
