About this 1.7ct natural oval diamond

This 1.7ct natural oval sits in the one-and-a-half to two carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6542565251. Listed at 18 retailers as of November 2, 2026, with prices from $15,646 to $30,542, a $14,896 spread on the same certified stone. MOH London lists it at $30,542. 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.
