About this 3.78ct lab-grown oval diamond

This 3.78ct lab-grown oval sits in the three to five carat band, graded G colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 7438959159. Listed at 18 retailers as of October 27, 2026, with a 354% 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.
