This 1.43ct lab-grown round sits in the one-and-a-quarter to one-and-a-half carat band, graded G colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG596311487 or 596311487. Listed at 7 retailers as of October 29, 2026, with prices from $402 to $1,182, a $780 spread on the same certified stone. MOH London lists it at $1,182. 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.
