About this 1.43ct lab-grown round diamond

This 1.43ct lab-grown round sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG756517001 or 756517001. Listed at 22 retailers as of October 29, 2026, with prices from $319 to $2,761, a $2,443 spread on the same certified stone. Brilliant Earth lists it at $2,761. 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.
