About this 0.78ct natural marquise diamond

This 0.78ct natural marquise sits in the just-under-one-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by HRD 13006144022. Listed at 11 retailers as of October 30, 2026, with prices from $2,343 to $6,274, a $3,931 spread on the same certified stone. NZ Jewellers lists it at $6,274. 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.
