Red Diamonds
Colored by intense pressure and a malformation in structure, these red diamonds for sale hold the rarest – and most valuable – coloring amongst all fancy colored diamonds for sale in the USA.
-
Orange Diamonds
Blue and yellow light cling to specifically arranged nitrogen atoms, providing it with a unique fancy orange diamond coloring.
-
Yellow Diamonds
A common color that is caused by nitrogen atoms. Unlike orange, atoms in yellow colored diamonds for sale don’t need a specific arrangement, due in part to their similarity to carbon atoms.
-
Green Diamonds
Unlike other diamond colours, green diamonds for sale in Canada and the USA get their colouring after formation from direct alpha, beta, and gamma particle radiation. The deeper the green, the rarer the diamond.
-
Blue Diamonds
This beautiful blue diamond colour is caused when boron contaminates the structure of a diamond during formation.
-
Purple Diamonds
While it’s not certain exactly how fancy purple diamonds in Canada are formed, they are an extremely rare & valuable colour of diamond.
-
Pink Diamonds
Much like red diamonds, the colouring is caused by a deformity in the structure that refracts light and absorbs green light, shining throughout the fancy pink coloured diamond.
-
Violet Diamonds
A hard to find diamond colour, when found, they tend to be small. While fancy violet diamonds for sale are a colour of their own, their chemical composition is a combination between blue and purple.
-
Brown Diamonds
Along with yellow & orange diamonds, brown diamonds in the USA and Canada get their colouring from nitrogen, as well as defects in the crystal’s structure.
-
Grey Diamonds
High amounts of hydrogen in the diamond’s composition cause it to absorb each colour of light equally, sort of how mixing each colour of paint with a bit of white makes grey.
