Miriam de Ungría´s constant pursuit of aesthetics and the need of being surrounded by beautiful things led her to spend five years at the Complutense University of Madrid, where she earned her degree in Geography and History, specializing in Art History. A year after the completion of her degree, her lifelong fascination with the world of jewellery led her to the European Centre of Gemmology and Jewellery at the University of Oviedo where she studied gemmology, jewellery manufacturing, wax moulding, gemstone setting and jewellery design, which she would later perfect in Italy.

The ensuing courses in diamonds, colour stones and pearls, as well as those of jewellery appraisal, would give her the credentials to pursue her career as a jewellery designer and appraiser.

She launched her first jewellery collection in 1991, introducing herself to a clientele that immediately vested their trust in her, not only for her designs but also for the appraisal of their most personal pieces of jewellery. Hence, she successfully brought together her two passions: design and gemmology.

In 1991 she, along with a group of gemmologists and appraisers, founded the Spanish Jewellery Appraisers’ Association (A.E.T.A.), which later served as its president.

Shortly thereafter, she would expand her professional horizons by collaborating with others in the sector. In January 2000, she joined forces with Spain’s premier international jewellery brand, Carrera y Carrera, on a major project to modernize and re-position the brand. As the Director of Fine Jewellery at Carrera y Carrera, she launched the “Garden of Roses” collection in New York in July 2002, the success of which enhanced her reputation and status internationally.

In 2014 she launched her biggest challenge: her own brand MdeU, which has been growing with the web site www.mdeu.es and corners at the El Corte Inglés department Store in Spain. She came out with three collections: “Heart&Roses”, “Asia” and “Limited Edition” and soon she added “Logo” and “Just say it”. Bracelets, necklaces, earrings, brooches, cufflinks…and even a small sample of pieces for the house “MdeU Home” with silver initials for an exclusive scented soaps which soon became a must.

Year 2016 started with two new collections: “Ellipse” and “Colour”, a renovated web site and a business plan focused in the international market, which took her to Dubai and Jordan. In January 2017, coinciding with the launch of “Universe” collection, she presented her designs in Bulgaria. Very much aware of the importance of the social media, MdeU is daily showing products in Facebook and Instagram and updating the web site.

In May 2017 presents “cLOVEr” a collection created for the jewellery brand “Chocrón”, based on a four-leaf clover in white and rose 18k gold and diamonds.

The end of year 2018 is a new turning point; Miriam de Ungría moves to London looking for a business opportunity, after the positive results of the trunk show organized two months earlier in this city. Her latest collection “Meninas”, first launched in Madrid and then London, is the most contemporary representation of the painting created by the universal maestro, Velazquez.

The 2019 exhibitions, taken place in Sofia (BULGARIA) London, UK (December 2018 and November 2019) and LUXEMBOURG (December 2019) show her increasing presence in Europe.

Year 2020 started with the recognition from the “Art and Culture” Foundation to her carrier as a gemmologist and jewellery designer.  Shortly after, another prize as best international jewellery designer was received from the Bulgarian Fashion Academy. She took the opportunity to exhibit her latest creations in Sofia, (BULGARIA) and shared a lecture about diamonds at the Unicredit Bank for the “Women in Business” Association

In 2020, Miriam de Ungría has launched a series of videos showing her gemmological and creative passion. Seen in all social media platforms (Instagram, Facebook, Linkedin and YouTube) these videos show tips, curiosities and interesting knowledge about the world of jewellery and gemmology.
