Guide to gemstones – some myths and legends
Guide to gemstones – some myths and legends.
Gemstones have played various roles in the myths and legends of human cultures throughout history.
Some tell a story or are believed to have special powers, but all of them share a common beauty.
Each gemstone is unique with a special colour, birthplace and story.
Gemstones come in every colour of the rainbow and are gathered from all corners of the world.
With each coloured gemstone possessing a unique creation of beautiful colour.
Some gemstones have been treasure since before history began and others were discovered only recently.
At the beginning of each month comes a new stone, some months have two gemstones and lucky me, December as three!!!!!!!!
Some stones I will post about aren’t associated with any month, but that doesn’t make them any less fascinating or stunning
As you will see as we progress through the year.
Fancy Coloured Diamonds
Fancy coloured diamonds are true miracles of nature.
The geological conditions needed to create these colours are rare.
Making them scarce and highly priced.
As well as highly prized.
They come in pale pinks, blues, bright yellows, oranges, greens, reds, and brown colours.
Although brown doesn’t sound very diamond like.
However, call them cognac, champagne or even chocolate diamonds.
And you have transformed something which could be perceived as dull and boring to something enticing and exotic.
Fancy colour diamonds are evaluated by their colour intensity unlike colourless diamonds that are graded on their fire and brilliance.
Shades that are deep and distinct in colour are rated higher than light or pale shades.
The GIA (Gemilogical Institute of America) describes colour in terms of hue, tone, and saturation.
- Hue – refers to the diamonds colour
- Tone – relates to the colours lightness or darkness
- Saturation describes the colours depth.
Using highly controlled viewing conditions and colour comparisons, a fancy colour grader , yes that is an actual job, selects one of 27 hues.
Then describes tone and saturation with terms such as “fancy light”, “fancy vivid” and finally “fancy intense”
This colour system was developed by the GIA and is used worldwide.
Today, yellow diamonds are thought of as “traditional” and are among the most abundant of all fancy coloured diamonds.
Blue, red, black and green diamonds are generally thought of as rare however we are seeing an increase in availability.
Pinks, oranges, and purples are extremely rare and so therefore highly sought after which inevitably increases the price as we all know.
And with DeBeers announcement, last year, that the Argyle mine will be closing in 2020, who knows where the price of diamonds will end.
