Yes. We have found hundreds. One of the most prominent examples is the burial of Volnikovka, which is rather recent (published c. 2014). But we've been finding Hun artefacts since the 19th century, although sometimes they were mislabelled as Germanic early on. Altlussheim, Szermabisenyo, Brut, Nagyszeklos, Concesti, and a dozen other sites have yielded many fine examples of late antique craftsmanship including gold and garnet cloisonne swords and other fittings.

I have a few images of some Hunnish military artefacts saved here, including belt fittings, swords, and helmets: https://www.pinterest.com/evanschultheis/hunnish-artefacts/

There's also a great paper on Hunnish Women's dress here.

This paper shows off a burial I'm trying to reconstruct from Singidunum.

Garnet Cloisonne was largely (although not purely - these steppe groups were always a mix of different ethnicities) a Hunnic introduction to Europe and there's some great papers on the technology of Cloisonne, which was quite advanced. The Huns also probably introduced the true Spangenhelmet to Europe, as none appear before the burials of Tsaritsyno, and the "Roman" ones (Leiden, Deir El Medineh, etc.) are all 6th-8th century, not 3rd-4th as they're sometimes mislabelled. They also introduced the narrow langseax, which eventually became the saber. They may have introduced buttons as well (buttons were extremely rare before the 6th century AD, they appear in the Celtic sphere and on very rare occasions pop up randomly in provincial Roman finds, but it's not until the reign of Anastasius in 491 that they become widespread in Roman dress, stemming from Eastern influences).
