About this 4.8ct lab-grown radiant diamond

This 4.8ct lab-grown radiant sits in the three to five carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG821654055 or 821654055. Listed at 4 retailers as of October 30, 2026, with prices from $4,524 to $10,025, a $5,500 spread on the same certified stone. Zales lists it at $10,025. 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.
