About this 1.25ct lab-grown marquise diamond

This 1.25ct lab-grown marquise 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 LG762545685 or 762545685. Listed at 13 retailers as of November 1, 2026, with prices from $653 to $2,214, a $1,561 spread on the same certified stone. With Clarity lists it at $2,214. 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.
