Famous Diamonds

Among the most well known diamonds is the Hope. This 45.52 carat steel blue diamond is currently on display at the Smithsonian. The legends of the ill-fortune and curse bestowed on the possessor of the Hope Diamond are many. This diamond was donated to the Smithsonian in 1958. The Hope was originally a rather flat, blocky 110-carat rough.

Diamond Scams

When it comes to diamonds, there are numerous scams to avoid. Most scams are minor, but there are some major ones that come up from time to time concerning the buying and selling of diamonds. Scams occur simply because most people who buy diamonds – for whatever reasons – don’t know that much about diamonds. Therefore, they are easily fooled.

Diamond

Diamond has remarkable optical characteristics. Because of its extremely rigid lattice, it can be contaminated by very few types of impurities, such as boron and nitrogen. Combined with wide transparency, this results in the clear, colorless appearance of most natural diamonds. Small amounts of defects or impurities (about one per million of lattice atoms) color diamond blue (boron), yellow (nitrogen), brown (lattice defects), green (radiation exposure), purple, pink, orange or red. Diamond also has relatively high optical dispersion (ability to disperse light of different colors), which results in its characteristic luster. Excellent optical and mechanical properties, combined with efficient marketing, make diamond the most popular gemstone.
