About this 1ct lab-grown round diamond

This 1ct lab-grown round sits in the classic one-carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG332899396 or 332899396. Listed at 2 retailers as of October 31, 2026, with prices from $652 to $1,331, a $679 spread on the same certified stone. Brilliant Earth lists it at $1,331. 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.
