About this 3.7ct lab-grown oval diamond

This 3.7ct 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 LG583313883 or 583313883. Listed at 21 retailers as of November 4, 2026, with prices from $2,437 to $10,231, a $7,794 spread on the same certified stone. Brilliant Earth lists it at $10,231. 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.
