What actually moves the price
- Carat weight - price climbs faster than size. A 2 carat stone costs 3–4x a 1 carat, not 2x, because large rough is exponentially rarer.
- Cut quality - the only C you should never compromise. It drives the sparkle that makes every other grade look better.
- Color and clarity - G–I color and VS1–SI1 clarity is where most buyers land: eye-clean, face-up white, and far cheaper than premium grades.
- Shape - emerald typically lists below round at the same quality, because round wastes more rough and carries more demand.
