This 0.27ct 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 LG693541860 or 693541860. Listed at 3 retailers as of October 28, 2026, with prices from £130 to £279, a £149 spread on the same certified stone. B2C Jewels lists it at £279. 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.
