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 SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG846647435 or 846647435. Listed at 10 retailers as of October 25, 2026, with prices from $349 to $1,206, a $857 spread on the same certified stone. MOH London lists it at $1,206. 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.
