Name That Star Trek Object

The dilithium crystals that Elaan wears?

 

Salt?

 

Silicon nodules ("no commercial value" as Vanderberg said ) are actually the Horta's eggs/children.

 

Wow, all three answers could be equally correct, but the real winner is ... @Methuselah Flint: Elaan's Dilithium Crystal Necklace!

Clue 1: One person's common object is another person's valuable object.

Common to the Troyians and Elasians, but valuable to the Klingons.

 

And so off we go...

Clue # 1
I don't think any of us have a clue what the purpose of this object is. Nevertheless, it is very noticeable - protruding, one might say.

 

Can't be the light probe on the sick bay bed as we had that before!

 

No it's not that object, but who says we can't repeat objects?

Clue # 2
People walk past me, but never do they touch me.

 

these wall fixtures?

 

I believe Billy Blackburn works on one during TLOZ... Another clue later..

 

Clue # 3
I am singular, and in only one place on the ship.

 

This corner wall-floor thing seen in engineering?

 

@ItsGreen ^^That doo-hickie is also prone to being found in corridors:

@Methuselah Flint I'm gonna go with McCoy's Hexapod Lizard wall art.

@Methuselah Flint Did someone forget that they were running this round of the game?

 

Woah hold on sir! I do have other things going on in my life

The above is all wrong I'm afraid. I do like the lizard wall art guess though

Clue # 4
The outer material appears to be made of a contemporary material to today.

 

@Methuselah Flint No offense intended...

 

No problem!

 

Clue # 5
Someone does get pretty emotional near where I am placed.

 

Clue # 6
I'm not even used to help solve the problem at hand.

 

This sick bay filter-ish thingy in The Deadly Years?
