Meet Mairi
The Founder of Maadrn Fine Jewels Inc.

As the Founder and head designer of Maadrn Fine Jewels Inc, Mairi Shewfelt is responsible for overseeing all facets of the company. She does a very thorough due diligence when choosing recycled, up-cycled, dead stock precious gemstones, diamonds and pearls. Seeking out gemologists and dealers globally that share her ‘Ethos’ for sustainability is an integral part of the company. She uses recycled gold and silver. She is passionate about her commitment to changing how jewelry is made and reducing toxic waste from mining and manufacturing. Her vision is to open the marketplace up for sustainable and ethical handmade jewelry that is both affordable and luxurious. Her jewelry is made in Toronto, Ontario. Her one-of-a-kind pieces are sought-after all over North America and Europe.

Mairi gained her vast business experience in the Fast Moving Consumer Goods (FMCG) market from her time spent as an executive at PepsiCo. She covered nine Asian Pacific countries that spanned their Snack Food, Drinks and Oats divisions. Prior to moving into the FMCG market, she worked as a currency and fixed-income trader for Chase Manhattan Bank in Toronto, Ont and London, England. Mairi has worked in the jewelry industry since 2014. Maadrn Fine Jewels is a vetted member of the Canadian Jewelers Association. 

Mairi enjoys getting involved in local charity events and supports local food banks. She is an avid supporter of My Sister Place and Anova in London Ont, which offers shelter, counselling and support for women and children experiencing mental health issues and abuse. Mairi also supports the Children’s Health Foundation in London, Ontario, along with the Canadian Cancer Society. Mairi sits on various boards in Canada. 

Mairi relocated from London England to Canada in 2017 to be closer to her family. She has two dogs and splits her time between Canada, England and Italy. 

“I founded Maadrn Fine Jewels to change the way people think about Luxury Jewelry. Eco-Luxury to me, is about taking care of yourself and the world we live in. For my business, it is about using recycled stones, ethical trading practices and production techniques that won’t harm the environment. Plus, making 95% of our jewelry in Canada is something to be proud of as we support our economy and its workers."
