How to get the Pierre Sinnoh
The Pierre Sinnoh is obtained from spinning Pokestops and Gyms. There is a very low drop chance of around 1% per spin to receive a Pierre Sinnoh or any of the other evolution item, and there is an equal chance of obtaining each of the 5 currently available items.
There's no way to ensure that the Pierre Sinnoh will drop, but with only 4 other items, there's a greater than 50% chance that you'll receive one once you've spun over 250 Pokéstops.
The 7th day streak bonus gives you a very high chance of obtaining one of the evolution item, but it's not believed to be guaranteed.
