just a recomendation. round cut, around 1 ct, good color and clarity would go for around 2 g's, probly even less. Don't go to 47th street, they'll rip you off tremendously, instead make a trip to ac, they have about 9 jewelry shops, the best prices, in fact at least 50% of jewelers from 47th get their stuff from ac. if really interested i could put you in contact with a jeweler in there.
