USGS briefly summarized the Platinum Spike, 1889-90:



1889-91: Destabilization of the Silver Standard may have encouraged a form of commodity speculation in Russia, particularly for those merchant houses trading heavily with the USA.





1890/1: Base-metals didn't witness a price-hike, either.

The price of Platinum rose dramatically in 1889, evidently an attempt at 'cornering the market.' It was suggested that dental patent holders & manufacturers were the culprits, in the 50% price hike.
