This 1.75ct lab-grown radiant sits in the one-and-a-half to two carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG640491778 or 640491778. Listed at 21 retailers as of October 27, 2026, with prices from $253 to $2,250, a $1,997 spread on the same certified stone. Do Amore Diamonds lists it at $2,250. 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.
