Colored diamonds are frequently not given the attention that they deserve for the sole reason that people mistakenly believe that they are somehow inferior to classic, white diamonds. The truth is that colored diamonds appear by the same organic process just as white diamonds. Everybody who thinks less of colored diamonds should know that they are much more hard to come by.
On the Formation of Diamonds
We’ve all heard that diamonds are forever. Diamond doesn’t differ from graphite in its pure chemical element since they are both made out of carbon. However, the differences in allotropy make them poles apart in terms of their appearance, properties, and of course, their price. One of the reasons a diamond rock is more expensive than your graphite pencil is the structure of the molecules.
In graphite, we see the planes of hexagonal structures layered on top of one another so that every other layer lines up, and not the adjacent one. The bonds between carbon molecules in graphite are both strong covalent as well as weak interlayer bonds. Diamond carbon molecules, on the other hand, have only strong covalent bonds. The allotropy of diamond carbons consists of tetrahedral shapes throughout the spheres. All carbon bonds are connected, leaving no lone pairs.
The earth’s mantle, a layer below the crust and mantle, is the place that creates diamonds. The exact composition of the rocks from which the diamonds form is not known. The circulation of hot water and other fluids commonly found in the earth’s mantle is what alters the chemical composition of rocks, melting and dissolving them to create a new mineral.
From the pit of the earth that creates diamonds, hot magma rises with speed of up to 20 meters per second. In the case of diamonds, kimberlite rocks containing diamonds form volcanic kimberlite pipes. The vertical kimberlite pipes are how people were able to find diamonds that predate humankind itself.
Getting Familiar With Colored Diamonds
Colored diamonds are extraordinarily rare. Unlike white diamonds, colored diamonds have additional chemical constituents in the chemical formula or peculiarities in the chemical structure that result in a particular type of pigment.
Type 1 diamonds diluted with nitrogen atoms in big aggregates of even numbers give a color in the spectrum of dark yellow to brown. If there’s no pairing in the nitrogen atoms, it causes a lighter shade of the same tint, like intense bright yellow or brown. One example of non-paired nitrogen type 1 diamonds is the Canary diamond, accounting for just 10% of natural diamonds. Type 1 diamonds absorb ultraviolet and infrared radiation.
Type 2 diamonds get their color not by nitrogen impurities, but by anomalies in the chemical structure. Plastic deformation, coming from an exerted force or a change in temperature during crystal growth, can alter the color of the diamond. Type 2 diamonds color can be affected by crystal lattice distortion, boron in the crystal matrix, varying degrees of radiation, the inclusion of graphite, sulfides, and hydrogen content. Unlike type 1 diamonds, type 2 diamonds absorb infrared and transmit ultraviolet radiation.
Your Best Choice for Colored Diamonds
Diamonds have been a subject of controversy for far too long. With blood diamonds, also known as conflict diamonds coming from impoverished countries, many people’s stance on diamonds had started to dwindle. However, technology has come about with cutting-edge laboratories able to produce authentic synthetic diamonds. Regular diamonds take billions of years to form, while with the right equipment, you can have diamonds of any color created in just a few weeks.
Colored diamonds are not only a style statement but one of the best investment options you can make.
