About this 1.29ct lab-grown oval diamond

This 1.29ct lab-grown oval sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG840619126 or 840619126. Listed at 22 retailers as of October 31, 2026, with prices from $360 to $4,157, a $3,797 spread on the same certified stone. Brilliant Earth lists it at $4,157. 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.
