when do we find out garnet is a fusion
Garnet (Steven Universe) The first time viewers see Garnet's "fusion" become undone is in the episode "The Return", the succeeding episode "Jail Break" marking the first appearance of the two Gems that make up Garnet: Ruby and Sapphire. Her design also changed in that episode. According to Sugar, Garnet was intended to be a fusion since the pilot episode, though the characters of Ruby and Sapphire came into focus while Sugar was writing for Garnet. Sugar described the process as "reverse engineering" the two personalities based on what the production team brought to the show.[7] Garnet being a fusion of two Gems was a popular fan theory before it was revealed to be true in "Jail Break", as the writers included minor hints in various episodes. Neither character was given real depth in "Jail Break", but their presence explain how Garnet's two parts blend into one character. Ruby is characterized as feisty and aggressive, while Sapphire is stoic and contemplative, resulting in a complex dynamic when Garnet is fused together. Garnet's stable relationship while fused is used as a metaphor in the series, as Ruby and Sapphire together are stronger than any one Gem on their own.[3]
Diamond Most natural diamonds are formed at high temperature and pressure at depths of 140 to 190 kilometers (87 to 118 mi) in the Earth's mantle. Carbon-containing minerals provide the carbon source, and the growth occurs over periods from 1 billion to 3.3 billion years (25% to 75% of the age of the Earth). Diamonds are brought close to the Earth's surface through deep volcanic eruptions by magma, which cools into igneous rocks known as kimberlites and lamproites. Diamonds can also be produced synthetically in a HPHT method which approximately simulates the conditions in the Earth's mantle. An alternative, and completely different growth technique is chemical vapor deposition (CVD). Several non-diamond materials, which include cubic zirconia and silicon carbide and are often called diamond simulants, resemble diamond in appearance and many properties. Special gemological techniques have been developed to distinguish natural diamonds, synthetic diamonds, and diamond simulants. The word is from the ancient Greek ἀδάμας – adámas "unbreakable".
