Showcase-Ready
Your diamond hourglass arrives in premium presentation packaging with a black box and red satin interior lining. It also includes a quality wooden display stand designed to showcase the hourglass on any surface. The packaging makes this piece suitable for gifting or displaying in your own collection.
Shines Bright
These lab-grown diamonds are chemically and structurally identical to natural diamonds—atoms of carbon arranged in the same crystal lattice that makes diamond the hardest known substance. The only difference lies in the trace impurities that produce their distinctive yellowish-green hue. Fun fact: despite its hardness, diamond is still carbon, which burns in an oxygen-rich environment, producing a bright flame as it converts to CO2. But we don't recommend burning your diamonds in an oxygen atmosphere in a quartz tube to observe the bright flame—some things are just too beautiful to sacrifice to science.

The Weight of Time
Here's another surprise about your hourglass: the weight of this incredible device fluctuates as it operates. When you flip the hourglass over, it gets much lighter as the diamonds enter freefall. That changes when the diamonds hit the bottom—the momentum they gained as they fell comes into play. Weight is really a force, and the diamonds coming to rest in the bottom chamber contribute to it. For a brief moment, when the minute runs out and the last diamonds hit the bottom, the hourglass becomes much heavier!
