The song "Ruby Tuesday" was recorded by The Rolling Stones in 1966, released in January 1967. The song, coupled with "Let's Spend the Night Together", was a number-one hit in the United States and reached number three in the United Kingdom.
This set was made in January 2012 for an anonymous band member to commemorate a 45 year anniversary. Nearly 300 diamonds were incorporated.
Price and value were requested to be kept private.
A word about Color:
A ruby appears red because it absorbs all the other colors of white light (green and blue), while reflecting the red.
The color of any material is due to the nature of light itself. Daylight, often called white light, is actually all of the colors of the spectrum combined. When light strikes a material, most of the light is absorbed while a smaller amount of a particular frequency or wavelength is reflected. The part that is reflected reaches the eye as the perceived color.
The same material can exhibit different colors. For example ruby and sapphire have the same chemical composition (both are corundum) but exhibit different colors. Even the same gemstone can occur in many different colors: sapphires show different shades of blue and pink and "fancy sapphires" exhibit a whole range of other colors from yellow to orange-pink, the latter called "Padparadscha sapphire".
This difference in color is based on the atomic structure of the stone. Although the different stones formally have the same chemical composition, they are not exactly the same. Every now and then an atom is replaced by a completely different atom (and this could be as few as one in a million atoms). These so-called impurities are sufficient to absorb certain colors and leave the other colors unaffected.
For example, beryl, which is colorless in its pure mineral form, becomes emerald with chromium impurities. If manganese is added instead of chromium, beryl becomes pink morganite. With iron, it becomes aquamarine.
Some gemstone treatments make use of the fact that these impurities can be "manipulated", thus changing the color of the gem.
