Unfortunately, it is impossible to know from your description. You could post a picture on a "What is this Rock?" website and get several opinions.
No, quartz crystals are not cubic. They are hexagonal prisms with a six sided pyramid on the top.
Rainbow quartz is a term used for describeing two states of quartz crystal. One state, is a quartz crystal that has been fractured internally. The refraction of light through the crystal, produces a rainbow color spectrum. The second state, are quartz crystals that have been coated in titanium. The coating gives the surface of the quartz a rainbow effect.
Quartz is colorless when pure, but can be found in all colors of the rainbow.

Mystic quartz is not a naturally occurring stone. The rainbow colors are created by enhancing colorless stones like clear quartz or white topaz.
Quartz itself is transparent or transluscent. But trapped impurities such as iron, copper, etc give quartz a full rainbow of colors to choose from.
Quartz is a mineral that is formed by volcanic action. It is the second most common mineral. Feldspar is more common.
Halite typically forms cubic crystals with smooth faces, while quartz forms hexagonal prisms with pointed ends. Halite crystals are transparent and colorless, while quartz crystals can vary in color and are often translucent or opaque. Additionally, halite has a salty taste and is softer than quartz, which is a hard mineral.
I don't know where it is found. (in fact that is what i was searching for) but i can say what it looks like. Mystic quartz looks like an exploding rainbow (with a kaleidoscope effect) when light is refracted off of it correctly. (Answered by a 13 year old:))
Minerals species which crystallize in the hexagonal division are apatite, beryl, and high quartz. Minerals of this division tend to produce hexagonal prisms and pyramids. Example species which crystallize in the rhombohedral division are calcite, dolomite, low quartz, and tourmaline. Such minerals tend to produce rhombohedra and triangular prisms.
Objects that act as a prism include glass prisms, water droplets, and certain crystals like quartz. These materials can refract light, separating it into its component colors. For example, a glass prism can create a rainbow effect when white light passes through it. Additionally, natural phenomena like rainbows are formed when sunlight refracts through raindrops in the atmosphere.
Optical quartz is a high-purity form of quartz crystal known for its excellent optical properties, including transparency and low birefringence. It is often used in the manufacturing of optical components such as lenses, prisms, and windows, particularly in applications requiring precise light manipulation. Due to its stability and durability, optical quartz is also utilized in scientific instruments and telecommunications. Its unique properties make it essential in various fields, including electronics, photonics, and spectroscopy.
