Shine a flashlight closely on your stone. A real diamond will reflect white light and rainbow flashes. A fake diamond will likely not reflect much light.

Diamonds are rare and will only become rarer as time goes on. Tennis bracelets can hold their value and maybe even increase depending on demand. It's important to choose a bracelet that you can wear so that it's a worthwhile investment. That way, you can enjoy wearing it as its value grows.

A diamond disperses heat quickly and also dispels fog from its surface almost instantly. So, all you need to do is breathe on your diamond bracelet until the diamonds fog up. Then, note how long the fog remains on the diamonds. If it disappears in a few seconds, voila; the diamonds are real.

Each time the wearer reaches a life milestone – everything from earning a degree to giving birth – a new diamond can be added. Add-a-Diamond bracelets are designed to be beautiful, wearable pieces from the start, that become even more stunning over time, as more diamonds are added.
