This 1.4ct lab-grown radiant sits in the one-and-a-quarter to one-and-a-half carat band, graded G colour (near-colourless) and VVS1 clarity (very-very-slightly-included), with a standard cut grade and certified by IGI LG541272981 or 541272981. Listed at 13 retailers as of November 4, 2026, with prices from $284 to $1,786, a $1,501 spread on the same certified stone. Brilliant Earth lists it at $1,786. 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.
