About this 1.51ct natural oval diamond

This 1.51ct natural oval sits in the one-and-a-half to two carat band, graded K 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 6565197871. Listed at 13 retailers as of November 4, 2026, with prices from $4,926 to $8,991, a $4,064 spread on the same certified stone. Wholesale Diamonds Direct lists it at $8,991. 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.
