The idea is that the friend paid for it with the hard work and love that made it and the recipient repays the friend by honoring the work. Removing the bracelet before it naturally falls off is a sign that the friendship has gone sour. Another variation of this tradition is that the recipient of a bracelet is entitled to a wish. After the bracelet wears out and falls off naturally, the wish will come true.

In most cases, these variety names are historical, as the gemstones were not recognized as being varieties of other minerals until well after the name was in common use such as aquamarine, emerald, and heliodor as varieties of beryl.

Next, many gems are crystals which are classified by their crystal system such as cubic or trigonal or monoclinic. They may have luminescence and a distinctive absorption spectrum.

For example diamonds, which have a cubic crystal system, are often found as octahedrons.
