About this 1.23ct lab-grown oval diamond

This 1.23ct lab-grown oval sits in the classic one-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG815610251 or 815610251. Listed at 11 retailers as of October 30, 2026, with prices from $405 to $2,144, a $1,740 spread on the same certified stone. Reve Diamonds lists it at $2,144. 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.
