This 0.7ct lab-grown round sits in the half to three-quarter carat band, graded G colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI LG12455805 or 12455805. Listed at 3 retailers as of November 1, 2026, with prices from $449 to $1,616, a $1,167 spread on the same certified stone. MOH London lists it at $1,616. 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.
