The best birthstone jewelry for every month

the key to the best birthday gifts

We know it can be challenging to find brilliant birthday gifts for your best friend, mom, sister, and basically any girl in your life. (If you're anything like us, you'd rather give money or giftcards so she can buy exactly what she wants.) Fortunatley, there's the handy concept of the birthstone. We all have one, and these gems can be the answer to those gift-giving woes. Some girls even have two (if you were lucky to be born in June, October, or December). So, we hunted for the best birthstone jewelry in this roundup. Just be sure to find a piece that you know the birthday girl will want to wear!
