About this 1.7ct natural pear diamond

This 1.7ct natural pear sits in the one-and-a-half to two carat band, graded F 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 6435195039. Listed at 5 retailers as of October 28, 2026, with prices from $10,602 to $17,470, a $6,869 spread on the same certified stone. Cape Diamonds lists it at $17,470. 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.
