Diamonds have grading certificates for a reason, for your protection and your diamonds protection as well. Accuracy is very important to the beauty and value of your gemstone. It’s a good reason to remember the dates that your jewelry was bought or when it was given to you. Usually to go on with enhancing a stone, the clarity or inclusions have to be pretty visible. Thus, they drill holes into the flaws and bleach out the dark inclusions. This usually fills the holes or large inclusions that break the surface up with a compatible material.
The only problem is that this makes the diamond unstable, which means that it’ll be difficult for someone to work on the ring. Also, it can’t be cleaned in a real ultrasonic or steamed container. Diamonds are magnetic to oil and it needs to be heated to release the oil from the stone. There is no way to care for your diamond like a natural diamond. Find a nice GIA cert diamond SI 2 in clarity and F- G in color with a good make. Or, you can find an EGL SI1 EF as they are much more lenient in their grading.

Diamonds have been known since ancient times. They were originally used as a tool to carve other gems like lapis and carnelian.
Ancient Greeks believed that diamonds were splinters of stars that had fallen on earth. Some said that they were the tears of gods. Legend has it that there existed an inaccessible valley somewhere in Central Asia; a carpet of diamonds covered it. It was patrolled by prehistoric birds of prey and guarded by venomous snakes. However, the truth is that the exact origin of diamonds is still a mystery, to scientists and geologists.
Diamonds were formed as long ago as 3.5 billion years, under conditions of great heat and pressure, deep inside the earth. This correlates with the earliest stages of the development of our planet, estimated to be in the region of 4.5 billion years old.
Volcanic eruptions carried the diamonds to the surface of the earth millions of years ago. Diamonds are found in cone-shaped pipes of rock called kimberlitic. These pipes have been weathered and their diamonds dispersed by rivers to far-lying areas, such as coastlines. They should last for several million more years.
Prices for diamonds are determined for the most part by DeBeers Consolidated Mines which is the largest monopoly in the world. The prices are based on color, clarity, cutting proportions and carat weight.
