This 1.43ct lab-grown cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG836616331 or 836616331. Listed at 16 retailers as of October 29, 2026, with prices from $374 to $2,795, a $2,420 spread on the same certified stone. Helzberg Diamonds lists it at $2,795. 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.
