This 4.23ct 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 LG847685753 or 847685753. Listed at 6 retailers as of October 26, 2026, with prices from $3,440 to $10,686, a $7,246 spread on the same certified stone. Taylor and Hart lists it at $10,686. 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.
