This 4.63ct lab-grown radiant sits in the three to five carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG589390917 or 589390917. Listed at 14 retailers as of October 30, 2026, with prices from $795 to $3,350, a $2,555 spread on the same certified stone. Brilliant Earth lists it at $3,350. 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.
