Can a diamond break or chip?

Even though a diamond is one of the hardest naturally occurring substances on earth, it can still be broken. If struck hard enough from the right angle, a diamond can even shatter. It is important when storing your diamonds to keep them away from other diamonds in your jewelry box so that they won’t scratch each other.

The part of the diamond that is most likely to chip is the girdle The girdle refers to the widest part of the diamond where the crown meets the pavilion. If a diamond was the equivalent of the earth, the girdle would be the equator. (the widest part of the diamond where the crown The diamond crown refers to the collective facets above the girdle of the diamond. meets the pavilion The diamond pavilion refers to the collective facets below the girdle of the diamond ) and the culet. For this reason it is important to avoid diamonds with thin girdles. As for the culet The diamond culet refers to point at the very bottom. In some cases, the tip is polished off to form another facet. This is done to prevent accidental chipping. (the point at the bottom of the diamond), not all diamonds have a culet but those that do are so that it will not chip off.

How can you tell if a diamond is real?

One way to tell if a diamond is real is to take the diamond to a jeweler. The jeweler will magnify the diamond in question and perform a few harmless tests on the diamond to see how it performs. The absolute best way, however, is to send the diamond to the GIA The Gemological Institute of America is the world’s foremost authority on diamonds, colored stones, and pearls. They are responsible for the establishment of the four C’s and issue diamond and gemstone certification based on unbiased analysis of gemstone quality. so they can conduct a proper and unbiased test. They will also be able to certify the diamond for you. If your diamond is already certified, you can verify the number on the report with the GIA or whichever laboratory certified the stone and make sure that your certificate and diamond are authentic.

There is one exception when it comes to fluorescence. In cases where the diamond has a lower color grading, a strong blue fluorescence could counteract the subtle yellow tones.

On the other hand, if one of the stones was cut shallow to stretch the surface area of the stone, then it could appear larger. Having a stone that is too deep or too shallow is undesirable because it will not reflect light properly, making the stone appear smaller and dull.

In the case of gemstones, some gemstones are heavier than others. Rubies A Ruby has the same durability as a sapphire and is a reliable gemstone.
