About this 3.5ct natural oval diamond

This 3.5ct natural oval sits in the three to five carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1553679836. Listed at 13 retailers as of October 30, 2026, with prices from £31,424 to £50,648, a £19,224 spread on the same certified stone. Helzberg Diamonds lists it at £50,648. 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.
