Two forms of crystals are observed simultaneously for 3,4-MDPV with platinic bromide reagent. The light, orange-red, flat plates with angular or indented edges are very characteristic. The plates when oriented on their sides may appear as needles or blades. Under crossed polars, they are very bright and are observed in various colors- orange, yellow or green crystals. The second shapes of crystals observed are small, thick, rectangular orange tablets that grow individually or in twins.
