We are here to help you make a difference.

The “ethical jewelry movement” is now well underway with most companies aware that they need to know where their materials come from. Knowledge of material origins is a fundamental starting place to get to know one’s impact, but it is just the beginning. Knowing the origin does help us make future sourcing decisions and when paired with more on the ground engagement, can truly make a difference.
