color
Amethyst is the purple variety of quartz. Quartz is Silicon Dioxide SiO2. The color comes from trace elements of manganese/Iron Oxide Fe2O3. To get the best color and best uniform color amethyst is heated.
Aluminum is considered a trace mineral. Trace amounts of aluminum are commonly found in foods, but it is harmless in the natural form when eaten in moderation. Elemental aluminum can be toxic.
The Trace elements are related to Biochemistry, anyalitical chemistry, Geochemistry. Trace elements comes in all above chemistries. Go to Wikipedia.
We don't know exactly what you mean by "by the same process", but the color of minerals in general is highly sensitive to their exact chemical composition. Rubies and sapphires are the same mineral with slightly different trace elements. Transition metal ions in particular tend to be highly colored.
color
Yes. Value can be affected, particularly in collector specimens and those used in jewelry. The trace elements could either lower or raise the value of a specimen, and definitely affect the color of many minerals.
The color is derived from the elements in the mineral that accompany the silicon and oxygen in their chemical formula, their exposure to radiation, or the possible inclusion of trace elements or minerals.
Yes it is a mineral. SiO2 in composition. Commonly it can be coloured by trace elements such as iron.
A macro mineral is needed in large quantities whereas trace elements are minerals required in small quantities
A sapphire gem is mainly composed of the mineral corundum and other trace mineral impurities that give it its color.
Aquamarine is a varient of a mineral called beryl. It is composed primarily of beryllium, aluminum, silicon, and oxygen. The color of aquamarine is due to trace amounts of iron trapped in the crystal structure.
Many minerals have similar color, and mineral color can be altered by trace amounts of impurities or by weathering. A better indicator would be the mineral's streak, which is the color of the mineral when powdered, although this characteristic can't be used alone in mineral identification.
The blue color of beryl, variety aquamarine, is due to trace amounts of iron. The mineral is sometimes heat treated to bring out a stronger color.

A ruby is the gemstone form of the mineral corundum and some trace minerals that influence the color.
Vitamin CVvitamin C is a vitamin, not a trace mineral.
