About this 1.78ct natural oval diamond

This 1.78ct natural oval sits in the one-and-a-half to two carat band, graded M colour (faint-tinted) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 5563041937. Listed at 5 retailers as of November 6, 2026, with prices from $4,341 to $6,204, a $1,863 spread on the same certified stone. Yorxs lists it at $6,204. 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.
