About this 0.7ct lab-grown marquise diamond

This 0.7ct lab-grown marquise sits in the half to three-quarter carat band, graded I colour (near-colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG595300778 or 595300778. Listed at 4 retailers as of November 1, 2026, with prices from $1,849 to $2,947, a $1,098 spread on the same certified stone. MOH London lists it at $2,947. 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.
