A startup called Dust Identity raised $10m to grow its diamond-based security business. 

The company, which uses tiny bits of diamond dust to help manufacturers secure their supply chains against counterfeiters, offers a solution to manufacturers who are struggling to control the quality of all the pieces that go into their products.

Dust Identity mixes tiny, ground-up diamond fragments into a polymer and then sprays the whole mixture onto physical objects such as airplane parts or computer components.

When these objects dry, these tiny diamond fragments form a unique configuration that can be scanned into a database and used to authenticate objects as they move along a supply chain.
