About this 3ct natural oval diamond

This 3ct natural oval sits in the three to five 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 1423019706. Listed at 6 retailers as of October 27, 2026, with prices from £26,004 to £36,133, a £10,129 spread on the same certified stone. Cape Diamonds lists it at £36,133. 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.
