The stone names are pulled from the manufacturer's catalogue, and may not be 100% accurate or mistranslation. Hematite is clearly not correct, but what the stone is seems to be related. Due to a limited number of selections and needing so many unique choices, stones were chosen for their looks more than their properties.
