MARIARUBY

Title

Our Story

MARIARUBY is a brand inspired by Africa and its elements: its culture, animals, colors, the capulana (colorful fabric), fruits, beaches, traditions, instruments, the natural wealth of its tribes, art, traditional trees, and natural resources such as gemstones.

Cheila Gomes, the founder of the brand, met a woman named Maria, who earned a prominent place in the gemstone industry, representing her country at major international trade fairs. There, she gained knowledge and positioned her homeland on the map of gemstone and jewelry enthusiasts worldwide.

Maria’s remarkable sensitivity and entrepreneurial spirit led her to produce jewelry in Thailand, which she later sold to her fellow countrywomen. The name Maria is without a doubt one of the most beloved names in the world, and Ruby is among the most precious and desired gemstones.

For Cheila, the connection between the two names was simply perfect. Inspired by this story, the jewelry brand MARIARUBY was born.

CEO - Cheila Gomes

About the CEO

Cheila Gomes is the CEO and creative director of MariaRuby.

A Marketing Manager for 17 years, she worked for eight years in the extractive industry in Mozambique. One of the biggest milestones in her career as an employee was undoubtedly leading the public relations department of the world's largest ruby mine.

With a degree in Marketing, a Master's in Marketing & Advertising, and a Master's in Business Management in Oil & Natural Gas, she transitioned into the world of jewelry in 2022 and founded MARIARUBY.

She is passionate about jewelry, because when used in everyday life, it can represent self-confidence, love, friendships, deep connections, and inner resilience.

The fact that you worked with rubies, which are incredibly beautiful, powerful, and valuable stones, realizing their true value, and the way they stir the emotions of those who handle them, undoubtedly contributed to your vision and bold and courageous approach in creating the brand.

FROM THE CEO

Title

“Jewelry is not just an accessory, it’s a story you carry with you.”

CERTIFICATION, ETHICS & AUTHENTICITY

A piece of jewelry is typically made of a noble metal, such as gold, silver, platinum, rhodium, or palladium, often combined with gemstones. In our case, we are committed to marketing jewelry made with natural and sustainably sourced stones.

All of our gemstones come with certificates of origin and the Kimberley Process, which guarantee the authenticity of our products.

When it comes to cut gemstones, we maintain full control over their production, which also allows us to guarantee their authenticity after processing. Even so, once cut, our stones are sent to recognized laboratories to obtain a gemological certificate. This document, issued based on gemological examinations, provides detailed specifications about the stones, such as crystal system, species, family, origin, possible treatments, type of cut, refractive index, and other elements.

We care deeply about the safety and trust of our customers throughout the purchasing process, as concerns related to ethics and sustainability play a significant role in the decision-making process at the time of purchase.
