Larger arms are coated in diamond-like substance, with sharp points on the massive elbows. Those are Amethyst's arms protected by Emerald.
The smaller arms are proficient and skilled in pulling things apart quickly and precisely.

Both gems are creative and can make things in their own way. Their combined thoughts, they can tear anyone or anything apart.
Their form is based on the want to keep one another safe.
