Blue Topaz

“Blaze”
Imperial topaz and diamonds set in rose gold pendant
97.5-carat topaz
Designed by Lester Lampert of Lester Lampert, Inc.

The Imperial topaz in this pendant is 97.45 carats—the largest owned by any museum in the world.

The name supposedly refers to a tradition in the Ural Mountains of Russia, where shades of pink, orange, and red topaz (the rarest) were reserved for the family of the Czar.
The ancient Greeks believed that topaz gave them strength. In Europe during the Renaissance (the period from the 1300s to the 1600s) people thought that topaz could break magic spells and dispel anger. For centuries, many people in India have believed that topaz worn above the heart assures long life, beauty, and intelligence. (http://www.gia.edu/topaz-history-lore)

Many consumers are not aware that a blue topaz is caused by treatment. Blue is not its natural color. Also, topaz has many colors, which includes pink and purples that rival the finest fancy sapphires. Fancy sapphires have a mixture of colors that are not often found in a jewelry store.

Amethyst

Amethyst and pearl “Sun” brooch/pendant. Gold, Victorian. 2.5”.

Amethyst has a beautiful wine color and the Greeks associated it with Bacchus, the god of wine. Many believed that amethyst can keep its wearer clear headed or able to make rational business decisions as well as quick-witted in battle. If you wear it than it prevented drunkenness. Never knew a gem has that much power but the Greeks believed it.
There were legends for every gem that cultures have came across in time. Even today we have many legends about colors. The legend not to wear white after Labor Day. Another legend you only wear black to a funeral. Red roses mean romance. Yellow roses means friendship. Pink roses means love/appreciation. Orange roses mean enthusiasm. Imagine if those things were true.

Tourmaline

Tourmaline, Maine (top left-7.01 cts, top right-7.57 cts, center-3.96 cts, bottom left-5.61 cts, bottom right-5.95 cts)
For centuries people were confused as to what the gem tourmaline was. Until the development of modern mineralogy it was identified as some other stone, such as a ruby, sapphire, emerald, and so on because of its coloring.
It’s easy to understand why people confused the tourmaline with other gems: Very few gems match the gem’s dazzling range of colors. From rich reds to pastel pinks and peach colors, intense emerald greens to vivid yellows and deep blues, the breadth of this gem’s color range is unrivalled. Brazilian discoveries in the 1980s and 1990s heightened tourmaline’s appeal by bringing intense new hues to the marketplace. (http://www.gia.edu/tourmaline-history-lore)
Soon the gem was identified in the late 1800’s in California and it was known as the American gem by the Tiffany gemologist George F. Kunz.

Opal

opel
Opal is the product of seasonal rains that drenched dry ground in regions such as Australia’s semi-desert “outback.” The showers soaked deep into ancient underground rock, carrying dissolved silica (a compound of silicon and oxygen) downward. (http://www.gia.edu/opal)

During dry periods, much of the water evaporated, leaving solid deposits of silica in the cracks and between the layers of underground sedimentary rock. The silica deposits formed opal.

Tanzanite

Tenzanite
Tiffany and Co. recently discovered tanzanite and it is only found in one place on earth. It was found in a country named Tanzania. The gem was name after the country. Most crystals comes in different colors depending on viewing direction, but cutters have a choice to pick the bluish purple or the very favored pure blue or the violetish blue hue depending on how much weight the cutter wants to retain from the rough. Weight value in size and shape.
Tanzanite comes from the mineral Zoisite, which has a variety of colors. It is mined commercially only in one area of the world: the Merelani Hills of Tanzania.

Sapphire

3.08 ct. blue Kashmir sapphire. Unheated, cushion, antique mixed cut.
Blue sapphire belongs to the mineral species corundum. It can be a pure blue but ranges from greenish blue to violetish blue. The name “sapphire” can also apply to any corundum that’s not red and doesn’t qualify as ruby, another corundum variety. (http://www.gia.edu/sapphire)
There are not just blue and red sapphires. Sapphires can come in colors of violet, green, yellow, orange, pink, purple and intermediate hues. These sapphires are called the “fancy sapphires”. It can, also be parti-colored sapphires that shows a combination of different colors. Sapphires can change its colors according to the light of day or incandescent light.

Red Ruby

red ruby

Ruby is the most valuable variety of the corundum mineral species, which also includes sapphire. Rubies can command the highest per-carat price of any colored stone. This makes a ruby one of the most important gems in the colored stone market. Chromium is the trace element that causes the ruby’s red, which ranges from an orangey red to a purplish red. (http://www.gia.edu/ruby)

The redness of the Ruby comes from how much chromium is present or absence. The more chromium the red is brighter and the less chromium the lighter the color. The color is what makes the ruby so unique. The color red seems to catch people’s attention even if it’s a lighter red.

Emerald

Emerald is the green to greenish blue variety of beryl, a mineral species that also includes aquamarine as well as beryls in other colors. (http://www.gia.edu/emerald)
Gem experts differ on the degree of green that makes one stone an emerald and another stone a less-expensive green beryl. Some people in the trade tend to give the name emerald to any green beryl colored by chromium. But to most gemologists, gemological laboratories, and colored stone dealers, it is more correct to call a stone green beryl when its color is “too light” for it to be classified as emerald.
