In 2022, Marrin Costello Jewelry launched our sustainability initiative — where for every item purchased, a tree is planted. As of 2024, we have planted over 15,000 trees. 

In 2024, we began a new initiative — where for every item purchased, a water bottle is rescued.

As a small business, we believe in honoring transparency and authenticity. We have partnered with Greenspark to reduce our carbon footprint within all facets of our operations — so that our environmental impact is as kind and minimal as possible whilst we create beautiful products for you to enjoy and share for generations.


Now produced with an environmentally conscious stainless steel base, Marrin Costello Jewelry is crafted of heirloom quality to leave a lasting impression. Our product is guaranteed tarnish free, made to be part of your jewelry wardrobe forever more.  We source our products from manufacturers that are in compliance with local and national laws, respect the natural environment, and uphold the respect and safety of their workers.


We make a conscious effort to make sure as many products as possible from our packaging are crafted as compostable and biodegradable. All materials used are either recycled, recyclable, or reusable.


At Marrin Costello Jewelry, intention is behind every decision made. Each product is mindfully designed and crafted with you in mind, creating the perfect balance in our jewelry line. Any product that does not meet our quality control standards is offered to our customers at a heavily discounted price during our sales, donated to local charities, or used in collaboration with other brands for gifts with purchase and giveaways.
