About this 0.99ct lab-grown cushion diamond

This 0.99ct lab-grown cushion sits in the just-under-one-carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG636419056 or 636419056. Listed at 2 retailers as of October 29, 2026, with prices from $904 to $1,899, a $995 spread on the same certified stone. Shane Co lists it at $1,899. 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.
