Hi Santosh,
I sent you a PM in reply to yours. I agree that you should pick high quality, but within your budget. If her pearls are quite formal and in 18K, she might enjoy something that can be worn more casually, such as white South Sea pendant and earrings. Also check the Designers section on
www.thepearloutlet.com. There are some very unusual items there. Terry and his crew are very helpful.
