About this 1.5ct natural oval diamond

This 1.5ct natural oval sits in the one-and-a-half to two carat band, graded M colour (faint-tinted) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1559605877. Listed at 10 retailers as of November 1, 2026, with a 35% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface. 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.
