About this 1.75ct lab-grown radiant diamond

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 LG621491943 or 621491943. Listed at 20 retailers as of October 29, 2026, with prices from $450 to $4,006, a $3,556 spread on the same certified stone. Do Amore Diamonds lists it at $4,006. 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.
