ABOUT US
Valenza's gemological excellence: expertise and transparency in digital.
Masi's Legacy: From the Goldsmith's Shop to Digital Commerce
Our history is rooted in the goldsmithing and gemological traditions of Valenza, the beating heart of Italian fine jewelry. Pietre Preziose Online is the digital brand specializing in the supply of loose gemstones, born from the legacy and direct experience of Masi Gioielli, the company founded by brothers Umberto and Andrea Masi in 1988.
This deep connection with our parent company, which in turn was founded by founder Luigi Masi in 1957, allows us to bring to the e-commerce world not just a product, but a standard of excellence consolidated by decades of craftsmanship and selection.
Rigour and Selection: The Guarantee of Gemologist
Our uniqueness lies in the rigorous selection of raw materials. We are not just retailers: every single gemstone destined for our catalog is personally selected and verified by Graduated Gemologist Umberto Masi (HRD Antwerp 1987). This unparalleled technical expertise ensures that each stone possesses the purity, color, and rarity that define high-end jewelry.
The attention to detail and the highest quality standards, typical of Valenzano craftsmanship, guide every stage of our sourcing, ensuring that the purchased stones are perfectly suited for setting and creating fine jewelry.
Ethics, Transparency, and "Tailored" Service
Trust is the essential value in the gemstone trade. For this reason, we operate with maximum transparency regarding origin and authenticity. We supply exclusively natural gemstones, sourced from operators certified according to the Kimberly Process.
Our e-commerce platform is designed to make this collection of select gems accessible to private customers, discerning goldsmiths, designers, and collectors. Drawing on our experience, we offer a tailor-made consulting service that assists clients in finding the ideal gemstone—by type, cut, size, or rarity—transforming your vision into reality with the certainty of Masi quality.
Vision and Innovation of Form
Our commitment is not limited to buying and selling: it is fueled by constant research. We develop our collections based on in-depth studies of global trends and, above all, the exploration of unconventional stone cuts and shapes.
This daily connection with the Masi Gioielli fine jewelry workshops in Valenza provides us with a privileged perspective, allowing us to understand design needs and offer gems that inspire 21st-century jewelry creations.
