About this 1.4ct natural oval diamond

This 1.4ct natural oval sits in the one-and-a-quarter to one-and-a-half carat band, graded K colour (faint-tinted) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2547597634. Listed at 10 retailers as of November 2, 2026, with prices from $2,815 to $6,112, a $3,297 spread on the same certified stone. NZ Jewellers lists it at $6,112. 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.
