I would love to know your opinion: What do you think this crystal in the 18th opening of Shippuden is supposed to symbolise?

Bonds and or dreams

Given we explicitly see Naruto chase after bonds and connections with others,

And it’s even more evident with Sasuke actively avoiding, trying to attack and severe his bonds until he effectively finally strikes it down and in the background it shows him awakening his MS, showing he’s discarding his bonds but he didn’t fully destroy it partly because it’s his bond with Naruto can’t be broken, partially because his bond with Itachi.

Then there’s Sakura whose caught between the two bonds and dreams of Naruto and Sasuke.

I could have a full breakdown over opening 18

But to keep it short
It’s supposed to symbolize bonds and dreams

Edit: I’ll update this post with a proper breakdown over opening 18 once I have spare time

Supposed to represent bonds because as soon as Sasuke shows up, he tried to shoo the crystal away

Diamond is unbreakable

I saw this from a youtube comment:

It symbolizes peace, the people at the start were the people who gave their lives up for peace, thus letting it go down

Naruto tries to find peace but as time goes on it becomes harder and harder

Sasuke tries to find peace as well, but soon believes there’s no thing as true peace, and so tries to break it

Sakura’s peace represents both Sasuke and Naruto, who move further away from her, representing the two crystals

Kakashi and Obito’s peace, Rin is near but concurrently far and undetected

Madara is near finding his own peace, but Kaguya grabs it, losing it entirely

Everyone else tries to find peace, but they can’t catch it

In the end, Naruto catches the crystal, and he keeps it close to him, he keeps “peace” close to him. Sakura grabs it, and holds onto it firmly, not wanting to lose her “peace”. Sasuke punches it away, representing that he think that there is no peace, and will not accept it. And Itatchi catches it, and releases it to the viewer, representing his sacrifice for peace.

All that Naruto cares for

Bonds, for sure.
