You really need to see the diamonds for comparison yourself. Inclusions can look very different in each diamond depending on various factors:
- where the inclusion(s) is/are
- solitaire vs halo, 4 prong vs 6 prong
- how likely YOUR eyes would get drawn to the inclusions and get bothered by them
- how well the diamond is cut (this is the most important factor- if it’s Excellent across the board, it’ll hide inclusions very well)
That said, a 2.5 ct diamond is a large diamond. My diamond is a 2.65 VVS1 and is “flawless” to me.
