Yes, of course.
Seventy-five percent of diamonds mined are not gem-stone quality, because of their defects: inclusions of other matter pressed within the diamond lattice.
Gem diamonds also have defects and flaws, unless you find one that is classified as Flawless or Internally Flawless. That is the highest grade for diamond clarity and therefore will cost you the most should you find one you want to buy.
Purple diamonds get their color from the presence of hydrogen defects in the crystal lattice during their formation. These defects absorb certain wavelengths of light, giving the diamond a purple hue. The intensity of the color can vary depending on the concentration of these defects.
Gem-quality diamonds are coloured by the inclusion of trace minerals within the crystalline composition of the diamond. For example, nitrogen makes diamonds yellow and/or brown; boron gives diamonds a blue hue, and some coloured diamonds acquire their colour based on structural defects.
Green diamonds are referred to as "green diamonds". They get their color from natural radiation exposure that causes defects in the diamond's crystal lattice, resulting in the green hue. They are one of the rarest colored diamonds in the world.
There are over 300 shades of colour that natural diamonds come in including pink, black, red and yellow. This is because of mineral impurities and lattice defects in the diamond.
From Wikipedia: "The color of a diamond may be affected by chemical impurities and/or structural defects in the crystal lattice." You can read more about what impurities and defects cause which colours, below.
Brown diamonds are the most common color of diamonds found in the gem-quality category. There are several theories as to why diamonds are coloured brown. According to its Wikipedia entry:"Several causes have been identified, including irradiation treatment, nickel impurities and lattice defects associated with plastic deformation; the latter is considered as the predominant cause, especially in pure diamonds."

Diamonds exhibit a range of colors due to impurities, structural defects, and changes in their crystal lattice during formation. These variations can affect how light is absorbed and reflected, resulting in the different hues, including pink, yellow, blue, and green. Natural fancy colored diamonds are rarer than colorless diamonds, making them highly prized in the jewelry market.
Yellow diamonds, like all colored diamonds, get their color due to impurities or structural defects in the diamond crystal lattice during formation. In the case of yellow diamonds, nitrogen atoms are present in the crystal lattice, absorbing blue light and resulting in a yellow hue. The intensity of the yellow color can vary depending on the amount and distribution of nitrogen in the diamond.
Diamonds come in a variety of colors, including white, yellow, brown, blue, pink, green, and black. These colors can be naturally occurring due to trace elements or structural defects in the diamond's crystal lattice, or they can be enhanced through treatments. Fancy colored diamonds are highly prized for their rarity and unique beauty.
Blue diamonds are rarer and more valuable than red diamonds. The presence of the boron element in blue diamonds gives them their color, while red diamonds get their color from structural defects in the crystal lattice. Both colors are extremely rare and highly prized by collectors and investors.
Some diamonds are coloured based on the inclusion of other minerals within the carbon crystal: nitrogen being most common, which gives diamonds a yellow cast. In the case of a red diamond, however, it is the type of diamond, a Type IIa, which gives it its colour. Type IIa diamonds are coloured based on 'structural anomalies" that exist in the stone based on 'plastic deformation'. (These deformations are caused by the "non-reversible changes" in shape that occur under the enormous pressure required to form diamonds deep within the earth's mantel.) Other colours produced by this natural phenomenon include pink and brown.
