About this 3.55ct lab-grown oval diamond

This 3.55ct lab-grown oval sits in the three to five carat band, graded F colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG727546755 or 727546755. Listed at 7 retailers as of October 28, 2026, with prices from $2,704 to $9,803, a $7,099 spread on the same certified stone. Rare Carat lists it at $9,803. 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.
