About this 0.99ct lab-grown round diamond

This 0.99ct lab-grown round sits in the just-under-one-carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG849651536 or 849651536. Listed at 8 retailers as of October 27, 2026, with prices from $125 to $499, a $374 spread on the same certified stone. NZ Jewellers lists it at $499. 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.
