About this 0.28ct lab-grown round diamond

This 0.28ct lab-grown round sits in the sub-half-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG659440645 or 659440645. Listed at 3 retailers as of October 29, 2026, with prices from $210 to $325, a $115 spread on the same certified stone. B2C Jewels lists it at $325. 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.
