Lab diamonds are gems with special properties that are not found in other types of stones. They are rare and are usually very expensive. Here are a few things you should know about them.
Colors available
Colored diamonds are now becoming very popular, and it is easy to see why. This kind of jewelry is unique, bold, and exciting. However, there are a few things to keep in mind when buying a lab created diamond.
First, you should consider what color grade you want your lab created diamond to have. This is an important factor in determining its price. For example, if you are considering a diamond with a rich, dark color, the cost will be higher than if it was a more muted shade.
Generally, you’ll want to buy a diamond that is at least in the G-J range. These stones should have no noticeable tinting and are also a good match for your center stone.
Resale value
If you’re planning to sell your lab diamond, you’ll want to know its resale value. A diamond’s resale value is influenced by several factors.
For starters, a mined diamond’s resale value will be far more than a man-made one. The reason is that mined diamonds are natural and are created by Mother Nature. It’s also important to keep in mind that mined diamonds are also very expensive. That means they can drain your retirement account and put a dent in your emergency fund.
On the other hand, a man-made diamond can be purchased for up to twenty to forty percent less than a mined diamond. This allows you to purchase a large gemstone at a reasonable price, while still preserving some semblance of your hard-earned cash.
Crystal structure
Lab diamonds are man-made diamonds that have the same physical and chemical properties as a natural diamond. This means that you can be sure that you are getting a beautiful and durable gemstone.
There are two main techniques used to produce lab diamonds. The first one is the High Pressure High Temperature (HPHT) technique. In this process, a small diamond seed is placed inside a chamber filled with carbon rich gases. This is then heated to more than 1,400 Fahrenheit. This enables the atoms to crystallize and form the diamond structure. The result is a flat, cubic, tabular diamond.
A second method of producing lab diamonds is by using Chemical Vapor Deposition. This process uses a small diamond seed to form a diamond. This crystal is then polished and placed back into the chamber for more growth.
Chemical composition
Lab diamonds are crystalline form of carbon created in a controlled laboratory. These diamonds are the same as mined diamonds but with enhanced color, clarity, and physical properties.
Unlike natural diamonds, which are formed over billions of years, lab diamonds are created in a laboratory. The chemical composition of lab diamonds is carbon-based, which proves they are real.
The process of creating a lab-grown diamond involves high-pressure synthesis processes and machines that mimic the natural conditions of the mantle of the Earth. A lot of hype has been whipped up around these lab diamonds in recent years. Nevertheless, a number of people still prefer to buy a natural diamond.
Physical and optical properties
Lab diamonds are synthetically created gemstones which have the same physical and optical properties of real gemstones. However, these synthetic stones are not as durable as the real thing.
There are several ways to produce lab grown diamonds London. One of them is the Chemical Vapor Deposition method. This method involves the breaking down of carbon-rich gas in the presence of a catalyst metal. The resulting carbon atoms then bond to the seed crystal of the diamond.
Another method is the High Pressure, High Temperature (HPHT) process. This process requires the use of a carbon source and temperatures between 1350 and 1600degC. This process produces a more complex morphology.
Grading process
For many years, GIA didn’t grade lab-grown diamonds the same way that they do natural diamonds. This has changed recently. However, GIA still doesn’t grade lab-grown diamonds according to the Four C grading scale.
GIA’s inventory control department is a hub for its laboratory operations. This department is staffed with highly trained personnel. Its responsibilities include maintaining a random distribution of diamonds and using the best support technology. It also provides a place to examine each step of the grading process.
Last speech
Unlike other diamond grading reports, the IGI Diamond Report doesn’t contain a proportions diagram. Its cut grades are assigned within a range of Ideal, Good, and Good Plus. These grades reflect GIA’s own set of standards.
