Before you read this blog, keep in mind that I have the mindset that you're caught up with Steven Universe, or more specifically, Steven Summer Adventures. So if you haven't watched all of SSA, then please do so.

Alright, so in the episode, "Back to the Moon Part 2," we learn that Pink Diamond, was shattered by none other then Rose Quartz. What we don't know, is what she did with the shattered pieces. Or do we?

We don't know exactly how many pieces she was shattered into, so lets think of a reasonable amount of places where it could be.

1. The Laser Light Cannon
In the second episode of Steven Universe (Which is one of my favorites btw), we find that Rose owned a laser light cannon. In the shot that the crystal gems use it, we can see inside of the cannon. In there, we see a gem, which is quite possibly a shard of Pink Diamond. This is possible, because we know that gems can be put into objects and be used, like when Lapis Lazuli was trapped in the mirror. So, how does this hold up? Really well, actually. A theory on the internet going around is the fused weapon between Yellow, White, and Blue diamond is what caused corruption. Evidence for this, is when the weapon activates, we can see a bright light, that plays music, and has blue, yellow, and white in it. So how does this have anything to do with the cannon? Well, when the cannon activates, it plays music, and it's made of light. Sound familiar? *cough cough* fused weapon theory *cough*.

2. Lion
This one seems kind of bizarre, but bare with me. In the most recent episode of SU, we find that Rose owned a couple of lions. I believe that one of the shards is in Lion. It's sort of like how in the episode, "Frybo," the gem shards Pearl had could possess certain objects. But if this is true, then where's the shard? There's two possibilities. One, it's under his mane. I mean, we never see under it, and in Lion 3: Straight to video, Steven says, "You never let me rub your belly!" (Or something along the lines of that). He probably doesn't want Steven touching his gem, most likely because he thinks he's Rose, and doesn't want to be shattered anymore. But a better theory is that it's inside Lion's mane. But...where? Well, look inside his mane.

Do you see it? No? Well, you do, actually. You just don't realize it. First, look at Pink Diamond's mural at the moon base.

Notice how by her legs, there's sort of gem/crystal things coming up from the ground? Well, look at the bottom of the tree in Lion's mane. I believe one of her shards are behind the tree, and somewhere in those gem things.

3. The Mysterious Temple Mural
As we see in Serious Steven, there's a mural with Rose battling Blue Diamond, and she appears to have a pinkish gem sort of thing, that's sending something out to attack Blue Diamond.

4. Steven's Shield
This one is highly unlikely, but what if Steven's shield is from a shard from Pink Diamond? Evidence for this is the fact that the gem on the shield, does not match Steven's/Rose' gem. The shield also destroys any gem magical thing, such as Lapis' water bending abilities, and Pearl's holograms.

So there's my personal theory, I hope you've enjoyed.
