About this 4.53ct lab-grown oval diamond

This 4.53ct lab-grown oval sits in the three to five carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG838643757 or 838643757. Listed at 22 retailers as of October 30, 2026, with prices from $5,778 to $24,260, a $18,481 spread on the same certified stone. Taylor and Hart lists it at $24,260. 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.
