Buying a graduation gift for your best friend can be such a wonderful adventure. It's for a person you know so well, but what is the right thing to get? Some kinds of things will seal the special friendship, but carry secrets that only the two of you know. Someday in the future will your "closer then a sibling" friend have to explain it to a spouse or kids? Does that even matter?
Its that connection you both understand and feel that you want to commemorate at this stage of life where so much will now be changing.
Something small, yet conveying the heart of the relationship, is often the best. Something that can be worn and seen in public, or be warn under some clothing so you both know but no one else. Or it can be safely stored on a display or in a jewelry box. The real value is not the item, but who it stands for.
When you shop, by far the most important thing is the right piece. It should fit the situation, and the personalities involved. Reviews are nice and the choices below are very well liked by people that have purchased them. Or there may be something on the list that is new with no reviews yet. Maybe you remember blowing dandelions with your "bestie" or have grown so close only a friendship bracelet with hand cuffs will do. Often a keychain is just right. No matter, workmanship is important. The type of material matters too. These come in stainless steel, zinc alloy, silver or gold.
