I need help with my boyfriends birthday gift?

Me and my boyfriend have the same birthday, and I wanted to get me and him matching bloodstone necklaces. I'm looking to spend around 100 dollars, and of course, a guy has to wear it, so it can't be girly. I'm going to buy it online, so if you know any sites that could help, can you please link them to me? I specifically want the necklaces to have bloodstone in it, but it can have other gems in it too, as long as there's bloodstone.
