About this 4.51ct lab-grown oval diamond

This 4.51ct lab-grown oval sits in the three to five carat band, graded F colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG839647932 or 839647932. Listed at 14 retailers as of October 27, 2026, with prices from $1,155 to $6,707, a $5,552 spread on the same certified stone. Brilliant Earth lists it at $6,707. 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.
