This 1.86ct lab-grown radiant sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG665403535 or 665403535. Listed at 14 retailers as of October 31, 2026, with prices from $564 to $4,045, a $3,481 spread on the same certified stone. Do Amore Diamonds lists it at $4,045. 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.
