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 $74,968 to $120,830, a $45,862 spread on the same certified stone. Helzberg Diamonds lists it at $120,830. 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.
