ABOUT US

SICA was born out of a desire to do things differently. The traditional diamond industry, with its history of unethical sourcing, environmental damage, and false marketing claims, inspired us to create a brand that stands for transparency, integrity, and responsibility.

At SICA, we believe that true luxury shouldn’t come at the cost of human rights or environmental sustainability. That’s why we source only conflict-free, ethically mined diamonds and gemstones. We partner with suppliers who share our values, ensuring that every stone is traced back to responsible origins.

Our mission is simple: to offer stunning, high-quality jewelry that you can wear with pride, knowing it was made with care for both people and the planet. We’ve set out to be a brand you can trust, offering honest information, fair pricing, and exceptional craftsmanship.

Join us in our journey to make the jewelry industry more transparent, ethical, and beautiful — because you deserve better, and so does the world.

Our Stones

At SICA, we are proud to offer an innovative alternative to traditional diamonds: lab-created synthetic stones that are virtually indistinguishable from natural diamonds. In collaboration with leading scientists and jewelry experts, we've developed a collection of synthetic stones that replicate the beauty, brilliance, and durability of mined diamonds.

Through advanced technology, our lab-created stones are formed under controlled conditions that mimic the natural diamond-growing process. The result is a stone that is chemically, physically, and optically identical to a natural diamond — but with a significantly lower environmental impact and no ethical concerns.

By embracing scientific innovation, we offer our customers the timeless elegance of diamonds while prioritizing sustainability, ethics, and affordability. With SICA, you can indulge in the luxury of diamonds, knowing that your choice is better for the planet and its people.

OUR MOISSANITE STONES

At SICA, we also offer Moissanite — a stunning alternative to both natural diamonds and lab-created synthetic stones. Moissanite is a gemstone that’s known for its incredible brilliance and fire, often outshining diamonds in its sparkle. Discovered over a century ago, Moissanite is now expertly crafted in laboratories to create beautiful, eco-friendly stones that are both sustainable and ethically sourced.

What makes Moissanite truly unique is its hardness and visual appeal. With a rating of 9.25 on the Mohs scale of hardness, Moissanite is one of the hardest gemstones available, second only to diamonds. Its exceptional brilliance, combined with its ethical origins, makes it a popular choice for those seeking an alternative to traditional diamonds.

At SICA, we proudly offer Moissanite pieces that provide the same stunning visual impact as diamonds, but with a significantly smaller carbon footprint and at a more accessible price point. With Moissanite, you can enjoy a brilliant, ethical gemstone that’s as timeless and beautiful as any diamond, without compromising your values.
