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 17 retailers as of November 2, 2026, with prices from $944 to $5,954, a $5,010 spread on the same certified stone. Brilliant Earth lists it at $5,954. 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.
