Proof of the collision of Nibiru's moons with Tiamat?

Could this be the first evidence of the collision between Tiamat and the moons of Nibiru? Scientists have discovered that tiny diamonds found inside a meteorite show signs of originating in a lost planet - one that dates back to the earliest days of the Solar System. Could this be from the destruction of Tiamat or maybe one of Nibirus moons? 
According to researchers from the École Polytechnique Fedérale de Lausanne, the diamonds from an asteroid called Almahata Sitta, which fell into the Nubian desert in October 2008, formed at pressures consistent with early Solar System protoplanets.
The researchers, led by planetary scientists Farhang Nabiei, studied the diamond inclusions inside the meteorite and found relatively large, individual diamond crystals up to 100 μm that could not have formed under an impact event, because of such an event's short duration, which would not allow time for such large crystals to form.
Nor, the researchers said, could chemical vapour deposition have produced the crystal sizes - which leaves static high pressure.
The other fascinating thing about diamonds is that, as they are forming, they often trap minerals present in their formation environment. Using transmission electron microscopy and electron energy-loss spectroscopy, the team analysed the Almahata Sitta diamonds to see what these mineral inclusions were.
They discovered chromite, phosphate and iron-nickel sulfide embedded in the diamond, with compositions and morphologies that could only have occurred under greater pressure than 20 gigapascals - nearly 200,000 times that of sea level atmospheric pressure.
Here on Earth, most diamonds are formed at around just 4.5 gigapascals. The team's result suggests that the diamonds in Almahata Sitta formed in a Mercury- to Mars-sized proto-planet. The moons of Nibiru that were destroyed when they collided with Tiamat were about this size, so could it be from the time of the destruction of Tiamat? Sill it is the FIRST proof that there was once other planets in the solar system.
