1. The Shattering Robonoid Wasn't Made To Identify A Gem's Identity, But Just To Scan Any Gem And Shatter

1. The Shattering Robonoid wasn't made to identify a Gem's Identity, but just to scan any gem and shatter them in areas where there's not much Homeworld activity anymore, where Off Colors are found. So why set it to not kill a Diamond when a diamond wouldn't even go there in the first place.

2. She had to, or needs to lie for Pink Diamond/Rose Quartz. She had to frame Pink Diamond as a bad person(because it's true anyway) and keep her secret identity.

3. Pearl's color palette is still the same when she shapeshifted to Rose, White skin, pink hair, blue eyes. It just appeared darker because of the nighttime palette. That's why the episode was called "A Single Pale Rose"

Rose Quartz appearing more peach is already confirmed by Ian JQ a long time ago that the reason why she's peach is because some Rose Quartz in real life have shades of peach. Peach is much like a closer shade of Pink. Even if it did meant to resemble humans which is Organic, then it would make sense since Pink Diamond is related to Organic Life. Maybe that's also the reason why she's the only Gem we know who can bear a human, because she's organic.

We've seen steven make color changes before because he's organic, by shapeshifting cats. And if that's not enough, Diamonds appear in different colors. Even a Pink Diamond in real life which is mostly pink has small traces of other rainbow colors. Because Diamonds are mostly transparent and refract light. In Pink Diamond, you can see few traces of Purple and Orange, sometimes blue and yellow. Other diamonds do these light to color refraction too.

(I'll just insert this, what makes me believe more that Diamonds are organic is because they are made of carbon, with some colors having chemical impurities. Carbon is the basic building block of life.) But Pink Diamond is the only diamond related to Organic Life.

4. Steven's insides are probably modified to work properly while having the sharp tip inside. After all, Steven is a diamond. He also has some healing saliva that works based on his emotions. So if something feels wrong, the healing will automatically respond until he and his insides feels alright.
