Traditionally, Australia has been a land more associated with opals than diamonds, and yet, the largest irradiated diamond in the world gave its name to the area where it was discovered: a small valley in the hills of Balwyn. No satisfying explanation of how the diamond came to be there (to say nothing of the circumstances of its irradiation) has ever been put forward. It is believed by some to have been a fragment of the Cranbourne meteorite, but if that were the case, there would surely have been other diamond fragments found. It is a puzzlement.
This confusion has not been helped at all by the fact that Deepdene did not, officially, exist between the years of 1927 (when the suburb’s railway station was closed) and 2010 (when it was officially granted suburb status by the Office of Geographic Names). It has been noted that these years coincide with the life of Doktor Heinrich Lantz, however this notation is incorrect (the Doktor was born in 1912, although he did first become a doktor in 1927) and is believed to have died in 1999 (although no body was ever found), and more compellingly, there is no record of Lantz even being aware of the existence of Deepdene. (To be fair, this may be due to a very successful coverup – Lantz was skilled at those.)
Today, Deepdene irrefutably exists, although it is possible that this existence is only a contingent one, and may be erased when the next trans-universal crisis event realigns and reweaves the timelines, as has happened many times in the past (notably, in 1927 and 2010).
