About this 4ct lab-grown oval diamond

This 4ct lab-grown oval sits in the three to five carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG754594936 or 754594936. Listed at 30 retailers as of October 30, 2026, with prices from $4,414 to $27,336, a $22,922 spread on the same certified stone. With Clarity lists it at $27,336. 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.
