About this 1.81ct lab-grown oval diamond

This 1.81ct lab-grown oval sits in the one-and-a-half to two carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2507434914. Listed at 3 retailers as of October 29, 2026, with prices from £894 to £1,141, a £247 spread on the same certified stone. GemTrove lists it at £1,141. 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.
