What Is The Rough Diamond Making Process?
Diamonds from deep within the earth over a very long period. The actual process that forms the diamond starts with carbon atoms coming together to form graphite. Which then moves through the following stages to become a diamond. Diamonds make up just one percent of all gemstones mined on earth. But they are treasured because of their beauty and rarity. Find out how they’re made below!
Step 1: Selecting Raw Diamonds
The mining and rough Diamond Making Process starts at a diamond mine. Diamond miners carefully dig through layers of dirt, rock, or kimberlite using explosives to discover diamonds. The largest stones are taken first, then smaller stones as they become easier to see. When there are no more diamonds in one layer of earth, miners move to another area. Repeat their search for diamonds. Each diamond mined goes through several cutting stages before it becomes a polished gemstone; most diamonds never make it past stage 2 because of their lack of size or flaws. To get from Stage 1 to Stage 2 (cutting), each stone has to go through extensive grading processes. Where individual experts check for clarity, color, and cut grade quality.
Sorted by color, shape, and polishing of Diamond
All diamonds must be sorted by color, shape, and weight before entering into a polishing machine. So that machines can be set up with only those diamonds that have similar qualities. As you can imagine, sorting thousands of diamonds by hand is quite time-consuming! This is why automated sorting machines have been developed over time to speed up the diamond selection process. Before any machine begins working on a diamond, it’s given an identification number which helps keep track of its progress throughout the entire rough diamond-making process. Some sorting machines look like mini-mills with huge spinning drums that crush large amounts of raw material while others use light sensors and computer algorithms to identify diamonds based on their unique properties.
Step 2: Grading Diamonds
After a diamond is found, it goes through grading before it can be sold. The grading process uses x-rays and computers to determine how big each diamond is, how clear it is, and how well-proportioned its shape is. A color grade measures a diamond’s yellowness; less yellow diamonds are considered more valuable. A clarity grade measures blemishes on a diamond’s surface. Many kinds of blemishes can affect the value—for example, diamonds with fewer internal inclusions are generally worth more money than those with many inclusions. Some diamonds also have flaws called birthmarks or irregularities, which decrease their value. Finally, a diamond’s cut affects its appearance: poorly cut diamonds look duller and smaller than they are. In general, diamonds with higher grades (clarity, color, cut) cost more money because they’re rarer and more valuable.
A diamond cutter looks at these grades when deciding where to place an order for rough diamonds from mines around the world.
Step 3: Faceting Rough Diamonds
Diamonds are graded on several qualities, including cut, color, and clarity. This makes it difficult to compare prices and assess the value of diamonds of different grades. For example, a diamond with an SI1 quality in most categories might have a higher price than one with an SI2 quality in all categories. But if both diamonds are cut in such a way that they’re easily identifiable as excellent-cut diamonds, it’s fair to say they’re worth about equal amounts. Diamonds should be assessed according to their values (rather than relative values) because otherwise, consumers can’t make fair comparisons among stones of different cuts—and thus can’t make informed decisions about how much money to spend on them.
So, for example, you wouldn’t want to purchase a diamond just because it was cheap or expensive just because it was expensive. You’d want to purchase one based on its intrinsic value. To get around these issues, the diamond scanner includes a third category: cut grade (which measures how well a diamond has been polished). The scale for grading diamonds by cut grade ranges from excellent down to very good, good, fair, and poor. A diamond rated at least excellent in terms of its polish will reflect light evenly across its surface so that when you look at it from above you’ll see what looks like a bright white star; diamonds rated lower will appear duller or darker when viewed from above.
Step 4: Cutting Polished Diamonds
In rough diamond cutting, diamonds are cut to enhance their clarity and improve their value. Because diamonds are extremely hard and heat resistant, it can be difficult to produce a polished surface that meets certain standards of quality. Diamonds with flaws or spots can easily damage cutting tools and compromise finished products. Therefore, strict selection criteria have been set to govern who receives rough stones to guarantee high-quality cuts. Diamond companies focus on specific regions because they know what kinds of geological formations produce top-quality diamonds. The Diamond planning process begins in areas where geologists and prospectors uncover raw crystals underground; those pieces are sold or leased by those governments through official channels or auction houses like Sotheby’s or Christie’s.
