About this 0.5ct lab-grown oval diamond

This 0.5ct lab-grown oval sits in the half to three-quarter carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG816658248 or 816658248. Listed at 16 retailers as of October 29, 2026, with prices from $297 to $1,959, a $1,661 spread on the same certified stone. Kay Jewelers lists it at $1,959. 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.
