There are different colors of diamonds because of the elements or chemicals that are in the structures what absorb wavelengths and give off the color is why there are different colors of diamonds. In the article it mentioned that “the absorption of wavelengths is dependent on the elements of present in the structure of the gemstone.” This comes to show that minerals absorb wavelengths of light and give off that light. The evidence supports the claim by coming to show that diamonds are depending the elements or chemicals do absorb light giving them different colors. Color is the wavelengths of visible light that an object radiates or absorbs so that's why we see color. In the article it states that ¨transition metals are capable of absorbing different wavelengths of visible light, giving off wide range of colors seen in gemstones.¨Knowing this we now know that colors are wavelengths of visible light that is absorbed.

What is color? Color is different kind of wavelengths of light. The different wavelengths of light can determined the color. Gemstones also have chemical structures that help absorb the different amount of light. Many gemstones are actually colorless this is usually called “Pure form” when it combines with the impurities in the gemstones structure it causes their coloration. Some of the gemstones don't have an element for it to absorb light at all so it would stay colorless. The transition metals have electrons the unpaired electrons are the ones that will absorb the light which would give the electrons a higher energy level than the paired electrons. This is the reason why gemstones and appear to have color and this is what color is.

Color is wavelengths of light, and each wavelength is a particular color. The color we see is a result of which wavelengths are reflected back to our eyes.  In the chemistry of color-changing alexandrite it says, “Alexandrite color is a consequence of impurities present in its chemical structure.” Another piece of evidence comes from from the podcast when the speaker says, “This is known as inter atomic charge transfer - the electron jumps from one molecular orbital to one belonging to a different atom and the energy required to make that jump is equal to the wavelength of light absorbed.” She also states, “The absorbed light is reflected and that’s why we see Prussian blue as blue.” This evidence supports my claim because color is made from the wavelength and is made when the wavelength of color is reflected back into our eyes. Alexandrite color does not remain the same and can change when placed in different sources of light. The color of an object is determined when the wavelengths of light that it reflects.

Gems are different colors because of the light. We perceive color depending on the wavelengths and the light. In the article, it says "Different colours of light have different wavelengths, so the exact wavelengths that are absorbed will affect the colour that the object appears.". This is showing that the reason there are different colored diamonds is because the wavelengths that are absorbed and the ight, will affect how we see colored diamonds.

Light  can reflect anywhere an example is how diamonds reflect and change color just for a while or while you different color the light. In the article "the Chemistry of Colour Changing Alexandrite" it tells us how Nordenskjöld is a gem that change color. Yes, it change color, because the light reflect to the gem and it change color.  It also say " "In daylight it’s blue-green, but under the artificial light in your home, it takes on a purple-red hue. The small amounts of chromium impurities cause this curious effect. Chromium ions absorb visible light strongly in the dark blue and yellow regions of the spectrum.". Based on this evidence Diamonds can  reflect different color of light.

There are different colors of diamonds because the chemical structures of gemstones absorb different wavelengths of light. The transition metals can absorb colored light. DIfferent transitional metals are capable of absorbing different wavelengths of visible light which allows a wide range of colors. Transition metals may be part of the chemical formula and can be present as impurities. A transition metal atom sits in the place of another atom which would usually occupy that position in the structure and can lead to an intense colouration.The different impurities of the gemstone structure allow different colors to show when light is reflected. The chemical bond change can change the whole color of the gemstone.

There are different colors of diamonds because some have different impurities in their structure which leads to their colouration. According to our notes it says” Some minerals are colorless an it is inclusion of impurities in their structure which leads to their colouration.” Another thing is the environment the diamonds are in. It affects the color of the diamonds. This is why there are different colors of diamonds.

Gems are different Colors because they absorb different types of light. For example,in the article, "The chemistry of color changing alexandrite" it states " alexandrite’s colour doesn’t remain the same and can vary when its placed in different light sources. In daylight it’s blue-green, but under the artificial light in your home it takes on a purple-red hue. The small amounts of chromium impurities cause this curious effect. Chromium ions absorb visible light strongly in the dark blue and yellow regions of the spectrum. Uniform white light gives alexandrite a purple-grey colour due to this. This supports my claim because it shows how how the gem changes color in diffrent types of light.

Different colors are caused by chemicals and the wavelengths they emit. From the provided sources we know that “Color is perceived by our eyes as wavelengths of light, certain chemicals can reflect or transmit light in visible light bands.” We also know that color is that color has to do with a substance's composition. So depending on the type of element, the color will differ. Such as strontium, which makes red, and sodium, which makes yellow. We know that these elements make these colors because when they are burned the flame is a certain color. All of this shows that different colors are caused by the chemicals they are made of, and the wavelengths that those elements emit.

Color is the reflection of light, different colored diamonds are depended on what light is reflected. The article "The Chemistry of Colour-Changing Alexandrite" tells how a gemstone can change color depending on what light is absorbed or reflected. My partner also got evidence that supports this claim. In that, color is based on the light spectrum and what we see is the light reflected. This evidence supports the claim that color is the reflection of light. So for example a red gemstone would be reflecting the red spectrum more so than any other light spectrum colors. That is why color is a reflection of light and that different colored diamonds are depended on which color is reflected.

Color is the chemical base of the object. For example the document says “ The origin of these colors have a chemical base and the precise colour can vary depending on the chemical composition of the gemstone.” Color is also the Visible Light we can see. The document says “We observe an object as color when it absorbs some wavelengths of visible light but not others,”It also says “An object that absorbs all wavelengths of visible light that pass through it but does not absorb red light will appear red”This means that all the  visible light wavelength that are absorbed by the object or mineral will appear the color that we see.

Gems are different colors because they absorb different wavelength of visible light. In the article ¨The chemistry of color changing alexandrite¨ said, the gem can change its colors in different light sources. It also showed the chromium ions absorb the visible light. And the other visible light it didn't absorb shows on the gem. This supports the claim because then other gems that don´t change color and stay the same color do the same but they absorb the wavelength of same visible light unlike the alexandrite.
