My son was originally looking for an asscher or princess shape ring of 1.5 to 2. carats with a budget of not over $10,000. His girlfriend wants a ring that looks BIG. A friend told me that a rose cut ring looks much bigger than it actually is and a 2 carat ring would look like 4 carots. However I am having a hard time getting any info about rose cut diamonds. Does anyone know anything about them. Any advise would be appreciated.
