Different Coloured Diamonds By: Carol Bell

Dressy colored stones are all the rage these days. Gemologists have developed new techniques of create variations that are affordable to the average individual - by administering treatments to less desirable stones. Those diamonds are given treatments of irradiation followed with intense heat which transforms brown and yellowish diamonds into lovely colored gems that are affordable. This produces breathtaking greens, blues, yellows, reds, purples and other variants. These colors are considered irreversible, but, there's a possibility they may change during repair work if intense heat is used.

Treatments such as irradiation make it feasible for more individuals to obtain these brilliantly colored diamonds since many natural colored examples are uncommon and also very costly. When seeking for colored examples you must assume that any affordable extravagant color diamond has undergone treatments. Ask about the stones source and ask to view a lab certification to check authenticity.

Synthetic colored stones are an additional option if having a colored rock is something you like but cannot really justify the cost. These are genuine diamonds, though they're created in a lab.

Naturally colored stones get the coloring from different trace constituents present in the stones, such as nitrogen, that produces a yellow diamond. Diamonds can gain color by exposure to radioactive particles throughout its creation and a demonstration of one affected by radiation like this would be a Green diamond.An additional way that a naturally colored stone gets color is by its inclusions. Though seen as flaws and undesirable in a colorless stone, formations give unique conditions and powerful flashes of color within a fancy color diamond. Bear in mind that normal fancy colored examples are very pricey, and as such, all that are labeled to be sold as natural should be accompanied with a certificate from a respected grading lab.

A 'fancy' gem is a natural one which has color which may change from almost any color – and many variations in between with shades that can range anywhere between weak to strong.

The most famous examples in the world are Color diamonds such as the Tiffany Diamond, which is yellow, along with the Hope Diamond which happens to be blue. Color diamonds possess a wonderful fiscal record as their value has not decreased on wholesale level for over thirty years. Pink and blue diamonds have doubled every 5 years in a strong economy. In the 70's you might have purchased an extremely good quality blue diamond for around 50,000 dollars and now that same stone would be worth between two to three million.
