Names for a New Element or Gemstone

Why Decamarkium? Well the Decamark is a generation 3 Pokemon glitch that exist in Pokémon Ruby, Sapphire and Emerald and it's my fave gen 3 Pokemon glitch. So yeah... It's self explainory. (It's only if it's a black and white gemstone that has a question mark in the centre of it)

If you end up reading my book series, Glitcher's Child (When I'll write it. And have it published) you'll know more why. But I'll say this. Rayquaza is my favourite Hoenn legendary Pokemon after Groundon. And well... Yeah... (That's if it's a metallic element)

I'm gonna name a gemstone after a meme site that I use.

If there's a gemstone that is black but if in the light it will change to yellow that isn't yet discovered. I'd call it after my favourite bird species, the Wagtails.

If its an undiscoved alkali metal, I'm gonna name it after someone on ImgFlip of the username of Sayo_nara_chick.

Red and Yellow at same time in a gemstone? Well obviously call it Blazikenite! (I wonder if that will mean that you can make a Blaziken mega evolve if Blaziken actually exist.)

I'm not even gonna bother explaining anymore. (Radioactive metal)

(Gemstone)

(Metal)
