About this 1.7ct lab-grown heart diamond

This 1.7ct lab-grown heart sits in the one-and-a-half to two carat band, graded F colour (colourless) and VVS1 clarity (very-very-slightly-included), with a standard cut grade and certified by IGI LG1203320 or 1203320. Listed at 2 retailers as of November 2, 2026, with a relatively tight 1% spread, which is unusual at this carat range and suggests competitive pricing across the listings. 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.
