About this 1.25ct lab-grown heart diamond

This 1.25ct lab-grown heart sits in the one-and-a-quarter to one-and-a-half carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 3495961607. Listed at 2 retailers as of November 4, 2026. 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.
