        ***AWESOME COLOUR CHANGE  *** GEMSTONE RING   Defining Color Change In Color Changing Gemstones Did you know there are such things as color changing gemstones? Some exquisite gemstones change color under different lighting sources from natural sunlight to florescent or different internal lights. These color changing gemstones come from many different families of minerals including Alexandrite, Garnets and some Sapphires. First let me point out that color change is defined by what you see between natural and artificial light. If you think about it for a moment, it will be obvious. Electric lights have only been around for a bit over a century, but the color change phenomena in color changing gemstones has been know for much longer. Originally, it was defined as the difference people saw between sun light and fire light, be that from a candle, oil lamp, or whatever. As incandescent light became common, the effect was the same as comparing sun light with fire light. so the definition was modified to be a comparison between natural and electric lights. Below are pictures of a Garnet. This is one of the most widely available color changing gemstones on the market today.   So why is it that only a few gemstones exhibit these dramatic color changes, since nearly all gemstone color depends on the nature of the illumination? The answer is that these color change gems have two, approximately equal-sized transmission windows. A red gemstone appears red because it absorbs all frequencies of light except for red. A gemstone that absorbs all frequencies except for blue and red light will appear blue when the light is rich in blue wavelengths (e.g., fluorescent light) and red when the light is rich in red wavelengths (e.g., incandescent lighting).  The Physics behind Color Changing Gemstones The actual mechanism behind color changing gemstones is quite simple. Every light source has a different fingerprint. That means that visible light can be made up of many different wavelengths that show different colors   In the image above it is easy to see that noon sunlight (the yellow line) has a relatively flat line that contains almost every color.   STONE SIZE: FACETED PEAR SHAPE 13 X 10 MM METAL: SOLID.925 STERLING SILVER  RING SIZE: 9 MORNING/ DAYLIGHT OR BRIGHT NIGHTLIGHT HOT PINK TAKEN WITH MY PHONE CAMERA   LATE AFTERNOON   LOW LIGHT/ EVENING LIGHTING TURNS TO AMETHYST GREEN PAYMENT WITHIN 48 HRS UNLESS OTHERWISE ARRANGED WITH SELLER    

            Tanzanite is known for the exquisite combination of purple and blue hues, one of the loveliest of gems that has been discovered in modern times. Tanzanite,discovered in Tanzania in 1967 and introduced to the world in 1968, is mined as a greenish yellowish brownish crystalline material that resembles Andalusite. Tanzanite is basically the Blue variety of "Zoisite", and mined in Tanzania just below the base of majestic Mount Kilamanjaro. Zoisite was originally used in lamp shades and other ornamental art carved items. Tanzanite has been adopted as a December birthstone by the American Gem Trade Association and shares its last-month-of-the-year membership with turquoise and zircon. Even though all the major industry associations agreed that the public would respond positively to a dynamic new birthstone choice for December, amending the birthstone list is like amending the Constitution. There must be compelling reason and wide support. The last time the birthstone list was revised was in 1912, when jewelry industry leaders met to give gems discovered since the formulation of the traditional list a shot at birthstone status. Alexandrite made the 1912 list, and now that Tanzanite has been given birthstone status it shows the degree to which this gem is revered by the trade and public alike. It's affordability and distinctive beauty have earned this gem a status that rivals Kashmir Blue Sapphire. Tanzanite can be cut to emphasize its blue or violet color component, so it can resemble the finest royal-blue sapphire or hint at amethyst purple. This color versatility has endeared this member of the Zoisite family to leading jewelry designers in America, Europe and Japan. Top Gem Tanzanite is very beautiful and looks great in jewelry. If you are considering Tanzanite, I stock some Top Gem colors of rich deep Intense blue/blue-violet. TREATMENTS  - Virtually every Tanzanite is heated to permanently change its color from it's orange-brown state to the spectacular violet-blue color for which this precious gemstone variety is known. Moderate heat (750 o -950 o  F) is applied to get the color you see today ranging from light blue/blue-violet to AAA+ Top Gem colors of rich deep Intense blue/blue-violet. The typical heat treatment process is a permanent process that does not adversely affect the durability of the gemstone, so there's no need to worry when you see this enhancement disclosed.  CARE  - Tanzanite is sensitive to sudden temperature changes that may cause cracking. The fracture is uneven and brittle and a jeweler's torch could fuse the gem, so it may be prudent to ask a Jeweler to remove the stone before applying his torch. Tanzanite is easily attacked by hydrochloric and hydrofluoric acid. Tanzanite should  never  be cleaned in an ultrasonic or steam cleaner, since this cleaning method can cause irreparable damage to the stone. I strongly recommend  Ionic  Cleaners and/or warm, soapy water and a soft brush as the best way to clean Tanzanite jewelry. Since Tanzanite is of the softer variety of gems, like emerald, I recommend it be handled as though it is was as soft as opal. Also, if mounted on a Ring, since rings are susceptible to knocks and abrasion, I recommend mounting in a bezel or protected with heavy prongs as much as possible.           PLEASE NOTE THAT THERE MIGHT BE VARIANCES IN COLOUR DUE TO DIFFERENT MONITORS OR VIEWING EQUIPMENT.   SHAPE OVAL FACET TREATMENT ROUTINELY HEATED WEIGHT 0.47ct ORIGIN ARUSHA, TANZANIA DIMENSIONS 6.03x3.97mm CLARITY TYPE I - VVS COLOUR VIOLET BLUE HARDNESS 6.5 LUSTRE ADAMANTINE QUANTITY 1                                                 GIA CLARITY CHART      PLEASE DO NOT ASSUME TO USE ANYTHING FROM THE MELBON SITES WITHOUT PRIOR PERMISSION.
