About this 3.73ct lab-grown radiant diamond

This 3.73ct lab-grown radiant sits in the three to five carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 3505516051. Listed at 21 retailers as of October 30, 2026, with prices from $1,041 to $4,216, a $3,175 spread on the same certified stone. Taylor and Hart lists it at $4,216. 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.
