Flawless Diamonds: common questions
Flawless vs. Internally Flawless?+
FL means no inclusions or surface blemishes at 10x; IF allows only microscopic surface marks. Both are visually identical to every human eye.
Is flawless clarity worth it?+
Not for visual sparkle — a VS1 looks the same on a hand. It's worth it for rarity, resale documentation, and the pleasure of owning statistical perfection.
