This 1.72ct lab-grown radiant sits in the one-and-a-half to two carat band, graded H colour (near-colourless) and VS2 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG589301033 or 589301033. Listed at 18 retailers as of October 31, 2026, with prices from $389 to $2,147, a $1,758 spread on the same certified stone. Brilliant Earth lists it at $2,147. 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.
