Why is there a line in the middle of my diamond?
The “crack” is a reflection from the diamond’s girdle and is a so-called girdle reflection. This phenomenon is caused by the pavilion facets and is the answer to the horizontal line in the diamond. The purpose is simply to protect the diamond. A thicker girdle protects better than a very thin girdle.
Are raw diamonds worth anything?
With few common inclusions, raw diamonds are more valuable than diamonds with several common flaws. A raw diamond which has a brownish or yellowish tint is stronger but less valuable. On the other side, diamond with less hue is far more valuable. Transparent and colorless diamonds are too rare to find.
Can you find diamonds in gravel?
During a hard rain, water washes through the plowed field, collecting heavy gravel and leaving it in low-lying areas. Diamonds are fairly heavy for their size and are often found near other heavy rocks and minerals, such as jasper, hematite, calcite and quartz.

Why are rough diamonds so cheap?
Simply put, rough diamonds are cheaper than their more polished counterparts, mostly because they haven’t undergone an expensive cutting and polishing process. This doesn’t mean they are any less spectacular; in fact, as we’ve said, their beauty lies in their natural and unpolished look.
Can sandpaper scratch a diamond?
No, sandpaper cannot scratch a diamond. The hardness of sand paper grit ranges between 7 and 9 on the Mohs scale, which makes sand paper softer than a diamond. Many people use sandpaper to test if a diamond is real or fake.
Why can’t you scratch a diamond?
The hardness of a diamond is a result of its very compact crystal structure. Diamond is the hardest known natural mineral on both the Mohs and Knoop scales, which characterize a mineral’s scratch resistance through the ability of a harder material to scratch a softer material.
Will fake diamonds float in water?
Real diamonds are incredibly dense, and often outmatch the fakes in density tests. To confirm this, fill a glass up with water and drop your diamond in. A fake diamond will most likely float on top or only sink to the middle while a real diamond will sink to the bottom thanks to its density.
