About this 1.27ct lab-grown oval diamond

This 1.27ct lab-grown oval sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG733514575 or 733514575. Listed at 25 retailers as of October 29, 2026, with prices from $312 to $3,300, a $2,988 spread on the same certified stone. Brilliant Earth lists it at $3,300. 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.
