When a natural -- not man-made diamond -- is radiated, the crystals containing trace amounts of minerals other than carbon, the natural, latent colour of the stone is enhanced.
Whenever a diamond is radiated, it is imperative that this process be documented, so that any potential buyer understands where the diamond 'got its colour'. A gemologist can determine whether or not a diamond has been irradiated and its colour, therefore, enhanced.
Intensely coloured diamonds are generally more valuable than diamonds with less prominent colours. As well, naturally coloured diamonds are more valuable than diamonds that have been enhanced.
The Hope Diamond is basically a blue diamond.
A shirt may appear to change color in the sun due to the bleaching effect of sunlight. Sunlight contains ultraviolet (UV) radiation, which can break down the dyes or pigments in the fabric, resulting in fading or discoloration. Additionally, some fabrics may be more prone to color fading or changing under prolonged sun exposure.
The Hope Diamond is a deep blue color due to traces of boron within the diamond's carbon structure. These boron impurities absorb red, yellow, and green light, resulting in the blue color that the diamond is famous for.
No, for a naturally coloured diamond, and yes, for a treated diamond with enhanced colour. Any diamond can be treated, either chemically or by radiation, to enhance its natural colour. Many naturally coloured diamonds require no treatment, because their colour is judged to be naturally ideal. A certified gemologist can identify a naturally coloured diamond, and can also identify and describe treatments to a diamond intended to enhance its natural colour.
A blue diamond is commonly referred to as a "blue diamond," but it is also known as a "fancy blue diamond" when it possesses a significant saturation of blue color. These diamonds get their color from the presence of boron in their crystal structure. Notable examples include the Hope Diamond and the Blue Moon Diamond, which are renowned for their stunning blue hues.
People who want to change the colour of a diamond use radiation, not a chemical.
An irradiated diamond is a diamond that has been exposed to controlled radiation to alter its color. This process can intensify or change the diamond's color, often resulting in hues like green, blue, or yellow. The irradiation treatment is permanent and does not affect the diamond's durability or structure.
A diamond reflects whatever light is available, and a diamond is cut to reflect the full spectrum of colour. As well, some diamonds may have a phosphorous 'afterglow' once a light source has been removed. But a diamond will not appear blue in direct sunlight and brown in artificial light. In that sense, a diamond will not change colour.
No natural diamond will change colour.
You cannot
Diamonds don't change colour; diamonds reflect a rainbow of colours, depending on the light. Stones that change colour are not diamonds, and if they are used as accents in a piece of diamond jewelery, they simply enhance the charm of the piece.
Mineral change color because of heat, light, or radiation
I'm sorry but its impossible
Natural green diamonds are extremely rare. You would call one a 'green diamond'. According to the GIA Web site: "Green diamonds get their color when radiation displaces carbon atoms from their normal positions in the crystal structure. This can happen naturally when diamond deposits lie near radioactive rocks, or artificially as a result of treatment by irradiation."
The color of Cherenkov radiation is typically blue.
Radiation does not typically have a color. Electromagnetic radiation such as visible light does have colors, but other forms of radiation like X-rays or gamma rays are not visible to the human eye and do not have a distinct color.
According to Wikipedia, the Dresden Green Diamond, the most famous green diamond, owes its "...unique apple green color is due to natural exposure to radioactive materials..." Some green diamonds are made more green after being irradiated in order to enhance its colour. This process treats or enhances a diamond, and therefore, makes it less valuable than a naturally coloured diamond. A certified gemologist can identify such diamonds.
