Lawrencium does not occur in nature, and it has no isotopes that last long enough to allow significant quantities to be accumulated. It is essentially a laboratory curiosity.

Sample from the Everest Set.
Up until the early 1990's a company in Russia sold a periodic table collection with element samples. At some point their American distributor sold off the remaining stock to a man who is now selling them on eBay. The samples (except gases) weigh about 0.25 grams each, and the whole set comes in a very nice wooden box with a printed periodic table in the lid.
Radioactive elements like this one are represented in this particular set by a non-radioactive dummy powder, which doesn't look anything like the real element. (In this case a sample of the pure element isn't really practical anyway since the element exists as a short-lived laboratory curiosity only.)
To learn more about the set you can visit my page about element collecting for a general description and information about how to buy one, or you can see photographs of all the samples from the set displayed on my website in a periodic table layout or with bigger pictures in numerical order.

Poster sample.
This photograph of Ernest Lawrence appears in my Photographic Periodic Table Poster representing lawrencium, which is named after him. This highly unstable element can't reasonably be photographed, and a picture of its namesake seemed like a reasonable alternative. The sample photograph includes text exactly as it appears in the poster, which you are encouraged to buy a copy of.
