Amethyst are two twin Gems who mainly do patrol duty. They are individually named Eighty-Four and Thirty-Three. They're two in one and partnered with each other. According to Yellow Diamond, twin Gems will not break when they touch each other, as demonstrated when the twins bash their heads together, much to the chagrin of their observers. They are both great at swordplay and were recommended to train Phos for a short time.

The twins work in tandem for a lot of things, often talking at the same time or finishing each other's sentences. No one really cares which is which anymore, including themselves.

~!Later, Thirty-Three expresses to Phos that they want to go to the moon with them to practice independence from their twin. Unknown to them, however, Eighty-Four overheard and later switched their hairstyle to deceive Phos, and went to the moon in Thirty-Three's place.

Amethyst 33 has recently learned to cope with their twin leaving, and believes after 200 years that they are alright. They think 84 is doing alright as well, and still feels connected to them.!~

In a world inhabited by crystalline lifeforms called The Lustrous, every unique gem must fight for their way of life against the threat of lunarians who would turn them into decorations. Phosphophyllite, the most fragile and brittle of gems, longs to join the battle. When Phos is instead assigned to complete a natural history of their world, it sounds like a dull and pointless task. But this new job brings Phos into contact with Cinnabar, a gem forced to live in isolation. Can Phos’s seemingly mundane assignment lead both Phos and Cinnabar to the fulfillment they desire?

In the mysterious future, crystalline organisms called Gems inhabit a world that has been destroyed by six meteors. Each Gem is assigned a role in order to fight against the Lunarians, a species who attacks them in order to shatter their bodies and use them as decorations. 
 
Phosphophyllite, also known as Phos, is a young and fragile Gem who dreams of helping their friends in the war effort. Instead, they are told to compile an encyclopedia because of their delicate condition. After begrudgingly embarking on this task, Phos meets Cinnabar, an intelligent gem who has been relegated to patrolling the isolated island at night because of the corrosive poison their body creates. After seeing how unhappy Cinnabar is, Phos decides to find a role that both of the rejected Gems can enjoy. Houseki no Kuni follows Phos' efforts to be useful and protect their fellow Gems.
