These are known as fancy-colour diamonds and are valued for the intensity of their colour. Intensely coloured diamonds are the rarest and most beautiful of nature's gem treasures. Rarity and desire are the two things that set the price of coloured diamonds. The most rare and prized in order are red, blue, pink, green, gold and then yellow, milky white, champagne and black.

PANTONE 2018 COLOUR OF THE YEAR

Posted on February 13, 2018 by Jan at Neville Jordan | 0 Comments

ULTRA VIOLET

 

Pantone has announced Ultra Violet as its Color of the Year for 2018, but just who are the experts that make this decision each December?

Pantone got its start in 1963. Founder Lawrence Herbert created a system for identifying, matching and communicating colors for consistency across the print and textile design industries. His initial work led to the Pantone Matching System, a book that standardized colors across these fields.

 

Purple has ancient associations with power and royalty. We also associate it with the mysterious — the cosmos, mysticism, and counterculture. Think of Prince, David Bowie, and Jimi Hendrix, alternative icons who favored this brilliant hue.

Ultra Violet-inspired gemstones include amethyst and tanzanite.

 

 

HOW BIG IS MY DIAMOND?

Did you wonder why a 2 carat diamond does not look twice as big as a 1 carat diamond?
 
The carat is a unit of mass which is used to weigh diamonds. 
 
Just because a diamond is twice as heavy as another stone, it doesn’t mean it will look twice as large as the other.

From rich reds to pastel pinks and peach, intense emerald greens to vivid yellows and deep blues, this gem’s colour range is unrivalled.The chemical composition is responsible for its colour.
 
Many tourmaline colour varieties have inspired their own trade names:

Rubellite is a name for pink, red, purplish red, orangy red, or brownish red tourmaline.
Paraíba is a greenish blue, or blue tourmaline from the state of Paraíba, Brazil.
Watermelon tourmaline is pink in the centre and green around the outside.

Heat can damage a tourmaline. High heat can alter the colour, and sudden temperature change (thermal shock) can cause fracturing.
