Welcome to the sparkling world of Geraldo, where exceptional diamond creations dazzle the eye. Where the finest craftsmanship meets the most advanced technology and where connoisseurs look for diamond-studded jewels of unsurpassed beauty and quality.

Where every product – be it a bracelet, a ring, a pendant, an earring or a necklace – is visually striking and different than anything else on the luxury market. Where craftsmen work hard throughout the entire creation process to ensure that mostly valued jewelry concepts – “aristocracy” and “heritage” are inherent in any piece of jewelry.


Fifteen years ago, out of pure happenstance, GERALDO’s founder met a brazilian widow who wished to create an incredible Jewellery piece as a tribute to her late husband’s dream.

The dream was to invisibly set together round diamonds making an innovative sphere-shape. Inspired by her story, the founder engineered the Diamond Sphere™, a technological enigma to even the most experienced jeweler and named the company GERALDO.

To guarantee success company recruited best of breed craftsmen, highly trained engineers and creative designers. The company was immediately recognized as a “Gem-maverick” creating nearly impossible bespoke and signature pieces.

Diamond Sphere

The biggest innovation of Geraldo Jewellery House was to come up with the new invisible setting technique applying it to round diamonds. Becoming patented proprietary technology, the invisible setting of round diamonds opened a new page not only in the brand’s history but in the jewellery industry with the introduction of the Diamond Sphere (Patent Design US D653 155S).

Unparalleled engineering work of craftsmen, invisible round diamonds are set together into a perfect sphere-shape making it a technological enigma to even the most experienced jewelers and jewellery lovers around the World.

invisible setting

Invisible setting is a method of setting gems, in which a mosaic-like array of stones seems to float seamlessly in a piece with no visible prongs or support (for instance, making 7 stones of 0.07 carat each to look as 1.5 carat single stone). In fact, they have been cut individually and very precisely with grooved girdles and are locked into a thin wire framework underneath.

Geraldo advanced the “invisible” technique to new horizons, improving the technology thus allowing to apply it for round diamonds but also to clear almost any design boundaries.
