Aluminium isn't a mineral (it doesn't occur naturally). Perhaps you are thinking of alumina, which does have transparent mineral forms called corundum (ruby, sapphire, padparadscha).
A ruby is not classified as a mineral ore; rather, it is a gemstone and a variety of the mineral corundum, composed primarily of aluminum oxide. Rubies get their red color from trace amounts of chromium. While they can be mined and are valuable, they do not serve as a source of metal or other industrial minerals, which is the typical definition of an ore.
Could be diamond, ruby, emerald, tourmaline.
It is OK, rubies are easy to make artificially as they are made out of Aluminium Oxide. However there is one particular gem mineral (Spinel) that looks like ruby and some of the world's most famous rubies are not rubies but Spinels. eg. the Black Prince's Ruby and the "Timur ruby" in the British Crown Jewels are in fact spinels.
The commercial name of the ruby is 'ruby rock'. In geological terms it is called as Goodletite. It is commonly found in Westland and New Zealand.
