Seven Fine


Seven Fine Gems has a long history. It is the result of the merger of two companies from the Neves family: Nevestones and Nevesgems. It is a story of success in which, side by side, man and nature introduce the world to the most beautiful Rubellites and Tourmalines ever mined.

Quality and respect are in our DNA

Seven Fine Gems represents one more step in the family’s search for perfection. Our passion for precious stones, respect for people and our commitment to our clients informs our unique extraction and cutting processes. The company is also responsible for the sales, marketing and exportation of the stones, adhering to the highest international standards at all stages.


Where We Are

From minas gerais

to world

The Neves family is known for the exquisite work it carries out in the Cruzeiro Mine, a mine it owns and which is a veritable natural treasure. The mine is located in Governador Valadares, Minas Gerais, an important gemological hub, 650 km from Rio de Janeiro and 980 km from São Paulo.



The Cruzeiro Mine is the world’s largest Tourmaline mine.

From the outside, the landscape is enchanting. Its interior seduces through the colors of its stones: Tourmaline and Rubellite. The Rubellite, which has an intense pinkish red hue, considered the most splendid in the world, and is our greatest treasure.

Our concern for the present and the future means that Seven Fine Gems ensures stable quantity, quality, variety and, principally, continued supply of Rubellites and Turmalines.



No stone is as plural as the Tourmaline. This is why it always surprises. Tourmaline is elegance. Exclusivity. Versatility.

A natural composition of rare beauty in the most varied tones, allowing the creation of jewelry in countless styles and trends.


Precious stones mesmerize and seduce. They bring poetry to our lives. Among the most desired stones is Rubellite. Its intense red hue and energy are unmistakable and it constantly inspires the production of magnificent jewels.

The Seven Fine Gems Rubellite is considered one of the greatest discoveries of its type in the world. It possesses a clarity and clearness that impress and make it irresistible to the beholder.
