About this 0.65ct lab-grown round diamond

This 0.65ct lab-grown round sits in the half to three-quarter carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG717551482 or 717551482. Listed at 5 retailers as of October 30, 2026, with prices from $647 to $1,155, a $508 spread on the same certified stone. Cape Diamonds lists it at $1,155. 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.
