The NFPA 704 Diamond, commonly referred to as the NFPA Hazard Diamond, provides a system for identifying the specific hazards of a material and the severity of the hazard that would occur during an emergency response. The system addresses the health, flammability, instability, and special hazards presented from short-term, acute exposures that could occur as a result of a fire, spill, or similar emergency.
The OSHA's Hazard Communication standard and the NFPA 704 standard were designed differently, however both systems use numbers which can lead to confusion. The NFPA 704 is used primarily by fire and emergency responders / safety personnel to quickly gather information regarding the hazards present.
The fact that there is so much to learn about diamonds is what makes them so fascinating, and we love teaching people all about them, which is why we have created this helpful guide, outlining everything you need to know about the fire of a diamond!
Generally, the lower the clarity of the gemstone, the less powerful the fire and sparkle in the stone will be. A diamond with poor clarity would have small imperfections on the surface that are visible to the naked eye, meaning light will be unable to enter inside the diamond and reflect out. Diamonds with a higher number of inclusions can often look dull and lacklustre. So keep an eye out for this when shopping for your perfect diamond. You can head to our diamond section on our page here.
Typically, diamonds with less colour allow more light to pass through, so, the whiter or transparent the stone, the greater the light dispersion. So, referring to the diamond colour guide below, a grade D, E or F diamond would give off the very best fire.
The fire of a diamond is just as important as other attributes, like brilliance and scintillation. As well as contributing to the overall beauty of your diamond, the fire also contributes to the quality of it.

NFPA 704 labels are required when a law says to put them on. NFPA 704 does not stipulate when a container, tank, or facility must be labeled with the 704 diamond. When another code, regulation, or an AHJ (Authority Having Jurisdiction) demands this type of labeling, it instructs you how to do so.
If the NFPA 704 diamond is required, an AHJ will determine where and how many it should be displayed. It must be apparent to any responders who may come upon it. On the other hand, there must be numerous signs on the outside of buildings in various locations or rooms. At the very least, there should be two placards next to each facility entrance/exterior storage area.
When looking at the NFPA fire diamond, yellow is for chemicals with high levels of instability. These numbers detail how susceptible materials react in various environments and can help you determine if they require caution while responding to an incident or spill. Responding personnel will use this number to determine if an area shall be evacuated or the fire fought from a protected location.

Hearts on Fire hand select the most beautiful diamonds on earth, choosing only rough diamond crystals that are internally clear and knot-free. By using only the most exceptional rough diamond crystals, our cut and polished gemstones have a clean, brilliant, and unmistakable sparkle in their finished form.
Every single one of Heart on Fire's diamonds, even the tiniest accent diamonds, has the signature Hearts & Fireburst pattern. This pattern is a result of the HOF cut, and a testament to its consistency. It is Heart on Fire's promise that every diamond in a piece of Hearts On Fire jewelry will sparkle with their signature brilliance.
At Hearts On Fire, octahedral or double pyramid diamond crystals are our preferred rough source. These rough diamond crystals are internally pure, meaning they are clear or nearly clear when they emerge from the ground. Octahedral rough diamond crystals are rare, and form only in high temperature and pressure conditions, so they are more difficult to source than diamonds with more visible inclusions, like crystals and debris that got trapped during formation.
When you purchase a Hearts On Fire diamond, you are buying The Most Perfectly Cut Diamond In The World . And this is more than just a marketing claim - Hearts On Fire is the ONLY diamond brand in the entire world that can make this exclusive statement of perfection.

With a precise selection of the rarest diamond crystals, our master craftsmen then cut and polish at 100x magnification, while the rest of the industry only operates at 10x magnification.

Hearts on Fire boasts its perfect cut as their trademark for their diamond jewelry. It is an exquisite choice for celebrities, lovers, and clients who want a natural and brilliant diamond for themselves or their loved ones.
Hearts on Fire diamonds are known and marketed as "World's Most Perfectly Cut Diamond." It is a bold statement, but they back it up with their rigorous process using their in-house formula and new technology.
The cut is the most important of the 4Cs (carat, color, clarity, and cut) in a diamond when it comes to sparkle and beauty. With Hearts on Fire's proprietary cut, they consistently produce diamonds that are brighter and sparkle better than other diamonds. Their patented cut enhances the diamond's color and clarity.
The brand name comes from the eight flawless "hearts," which you can see at the top. Meanwhile, the "fire" comes from the starburst arrangement visible at the bottom of the diamond. Combining these two designs creates the uniqueness of the Hearts on Fire Diamond.
Hearts on Fire are natural and genuine diamonds. These crystals undergo a rigorous process and standards to filter and take only the purest and finest rough crystals. Because of this, only 1/10 of 1% of the rough diamond crystals in the world can become a Hearts on Fire Diamond.
After choosing diamonds, they use vibration-free cutting wheels to cut and polish them, following the ideal proportions and symmetry. They polish these diamonds at 100x magnification, which is ten times what the industry requires.
All the diamonds from Hearts on Fire are naturally-mined crystals guaranteed to be conflict-free. They source them ethically and responsibly from Angola, Botswana, Canada, Namibia, Russia, and South Africa. They fully follow and comply with the Kimberley Process.
Fire refers to how well the diamond displays the colored light. A diamond with a rainbow-like appearance, like Hearts on Fire, is because the proportions from the diamond's top and bottom are correctly balanced. Otherwise, they will have a flat and dull appearance because they cannot reflect colored light properly.
The last element is scintillation, which refers to how well the diamond reflects light during movement. If there is high scintillation, it means the diamond has few spots where there is no sparkle. Additionally, a well-cut diamond, such as Hearts on Fire, has a surface area that produces a visible spark.
Aside from brilliance, fire, and scintillation, polish is also one factor to consider because it affects the diamond's ability to absorb, refract, and reflect light. The more polished and transparent a diamond is, the more sparkle it will have. That is why Hearts on Fire polishes its diamonds more than the industry standard.
American Gem Society (AGM) is a preeminent jewelry trade organization dedicated to protecting consumers by helping them know what they are buying. They evaluate each diamond and grade it based on its qualities and components. They also generate a report that includes details from cut quality to the carat weight.
The clarity ratings range from Flawless (absolutely no inclusions) to Slightly Included (slight characteristics not visible to the naked eye but visible under 10x magnification) on Hearts on Fire diamonds. So, you will not have to worry about seeing a major inclusion in your diamonds.
