How can I get it out?

Any ideas on how to get my diamonds and oil out of the jar without using heat and preferably without damaging the diamonds? (Challenge level: ⭐️⭐️⭐️⭐️⭐️)

The best solution I can think of currently is deep freezing and just scraping the jar and hoping it all comes out, but yes I now realize this was not a well planned idea 😂
