This 1.51ct 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 very-good cut grade and certified by IGI LG623412215 or 623412215. Listed at 23 retailers as of October 30, 2026, with prices from $481 to $4,986, a $4,505 spread on the same certified stone. Do Amore Diamonds lists it at $4,986. 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.
