About this 0.51ct natural oval diamond

This 0.51ct natural oval sits in the half to three-quarter carat band, graded I colour (near-colourless) and VS2 clarity (very-slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1537797556. Listed at 16 retailers as of November 4, 2026, with a 150% 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.
