STATEMENT: Topaz's Stoneheart form would be extremely weak, far weaker than Aventurine's. Reasoning: Numby.
Evidence 1: Aventurine's Stoneheart form is very shiny
Evidence 2: Topaz's Cornerstone is of a similar making to Aventurine's, and is also quite shiny; it is also undamaged, unlike Aventurine's Cornerstone
Evidence 3: Based on Evidences 1 and 2, it is clear that Topaz's Stoneheart form would be EVEN SHINIER than Aventurine's
Evidence 4: Numby likes to eat shiny things, therefore Numby would try to eat Topaz and would be nibbling on any shiny part of her Stoneheart form, jumping all over her and generally being a nuisance, and not paying any mind to us or anything else that Topaz is fighting. Trotters are also known to be extremely nimble, so Topaz would be unable to neutralize Numby.
Conclusion: this is clearly canon.
