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 standard cut grade stated by the retailer rather than the lab and certified by GIA 6531641977. Listed at 25 retailers as of November 4, 2026, with prices from $1,194 to $5,450, a $4,256 spread on the same certified stone. Taylor and Hart lists it at $5,450. 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.
