About Us

Diamonius is an innovative company founded to provide consumers with conflict-free jewelry. Diamonius is dedicated to creating high quality beautifully designed diamond alternative jewelry without the high social and environmental price tags associated with mined diamonds.

Every woman should have the opportunity to own extraordinary jewelry that is conflict-free, and has no negative environmental, economic or humanitarian effects. Diamonius’ philosophy is to provide all women with their dream jewelry at an affordable price without compromising luxury or elegance. We enable fashionistas to wear $150-200 rings that look visually identical to $2000-$8000 rings.

Diamonius uses only the highest quality lab created diamond simulants as substitutes for naturally mined diamonds. Diamonius diamond simulants truly capture all the brilliance and luxury of mined diamonds. Our Diamonius diamond simulants will not fade, discolor or cloud. Our diamond simulants are colorless and flawless. Diamonius diamond simulants are visually indistinguishable from a mined diamond except by specialized gemologist equipment. Synthetic diamonds are to follow.

To show our commitment to fighting the destruction that diamond mining does to our planet,
we donate 2.5% from every item sold to orphans in Sierra-Leone, a nation whose population has been greatly abused by armed conflict and indebted slavery due to diamonds exported to first world countries.

Diamonius is part of Worthington-Bronfman Ventures Inc.  Diamonius has shipping centers located in San Francisco, California; Williamsville, New York; Ontario and Quebec.  Items are usually shipped from our US facilities.
