This 1.4ct lab-grown radiant sits in the one-and-a-quarter to one-and-a-half carat band, graded F colour (colourless) and VVS1 clarity (very-very-slightly-included), with a standard cut grade and certified by IGI LG628450993 or 628450993. Listed at 18 retailers as of November 1, 2026, with prices from $245 to $2,100, a $1,855 spread on the same certified stone. Do Amore Diamonds lists it at $2,100. 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.
