About this 1.89ct lab-grown cushion diamond

This 1.89ct lab-grown cushion sits in the one-and-a-half to two 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 7528448709. Listed at 19 retailers as of October 30, 2026, with prices from $1,650 to $12,869, a $11,219 spread on the same certified stone. Do Amore Diamonds lists it at $12,869. 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.
