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 LG680559470 or 680559470. Listed at 9 retailers as of October 26, 2026, with prices from $1,771 to $10,593, a $8,822 spread on the same certified stone. Brilliant Earth lists it at $10,593. 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.
