Siminetti was founded in 2010 by our CEO Simon Powell combining his passion for mosaics and luxury surface finishes. Having worked in the mosaics industry for 12 years, Simon identified the many benefits Mother of Pearl could offer the market, taking inspiration from the mosaics of Pompeii and Herculaneum and so began his & the brand’s journey. We are a British company based in Chipping Campden near Stratford upon Avon, the home of the renowned playwright, William Shakespeare.

Today, the company has representation in 6 continents ranging from North America and the Middle East to Europe and India, supporting some of the World’s most luxurious commercial and residential projects with our range of 19 stunning colours of Mother of Pearl.

Offering an unrivalled knowledge of the Mother of Pearl industry, along with its prestigious lifelong partners, ensures all of our clients receive a surface finish and service of exceptional quality. 2021 is a year of development for the brand as we build upon on our new affiliation with Rubelli in Dubai and existing ambassadors internationally, whilst working on our next product launch in 2022 and transition into our new headquarters at the end of the year.


“To continually create inspirational luxury surfaces, that are crafted with passion, viewed with awe and are kind to the planet on which we live.”

– Simon Powell CEO
