About this 3.89ct lab-grown oval diamond

This 3.89ct lab-grown oval sits in the three to five carat band, graded F colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG728538815 or 728538815. Listed at 21 retailers as of November 1, 2026, with prices from $1,313 to $5,540, a $4,227 spread on the same certified stone. Rare Carat lists it at $5,540. 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.
