This 1.25ct lab-grown radiant sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG841690386 or 841690386. Listed at 16 retailers as of October 23, 2026, with prices from $491 to $2,230, a $1,739 spread on the same certified stone. Queensmith lists it at $2,230. 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.
