Brilliance, fluorescence, brightness, sparkle, scintillation... What do these terms remind you of? Most of you associate these words with diamonds. There’s one more word to be added to the list: fire.
What is diamond fire? Why is it important? How do you understand the fire of a diamond? In this blog, we take a deep dive into the world of lab-grown diamonds.
The fire of a diamond describes all the rainbow colors that are visible in a diamond when it is moved back and forth. Technically, fire is the dispersion of white light into radiant rainbow colors that make the colors sparkle. Also known as light dispersion, the fire of a diamond is the biggest factor that lends it beauty.
Lab-made diamonds are as natural as mined diamonds. Lab diamonds have the same chemical and physical properties as mined diamonds. These diamonds can offer fire as well as mined diamonds can. However, the fire quality of diamonds depends on factors such as diamond cut, color, shape, and clarity, among others. When all these factors of a lab diamond are of a high grade, the fire quality is good.
In the GIA lab, the fire of a diamond is measured by assessing the dispersion under LED lighting. A gemologist examines the fire's dispersion from many different angles. The higher the quality, the brighter and more colorful the flashes of light observed in the diamond.
In general, the smaller a diamond's table facet, the more fire it can emit. Because there is less space for crown facets to produce fire as table% grows, fire tends to decrease.
Here are some tips and cues to look for when exploring lab diamonds for the best fire:
Choose a lab-grown diamond with outstanding symmetry for plenty of diamond fire. This influences how the diamond bounces and refracts light, increasing the importance of those critical virtual facets. This is something that a gemologist can help you with.
Your best bet is definitely a triple-X lab-made diamond. This abbreviation stands for "triple excellent," which means "excellent cut, symmetry, and polish." This is one of the GIA certification grades that any diamond seller should go over with you before you buy.
A lot of factors impact the fire of a diamond, for example, such as diamond shape and cut, among others.
Assess the cut of a diamond. The better the diamond’s cut, the more visible its fire will be. For example, diamond cut grades range from deep cut, well cut, to shallow cut. A well-cut diamond will offer the most fire.
Another factor to assess is the diamond's clarity grade. Diamonds that have many flaws and inclusions fail to reflect light well and hence display poor fire.
Assess the diamond’s color to ascertain its fire quality. A whiter and more transparent diamond can disperse more light and hence offer better fire. Diamond colors of grades D, E, and F offer the most fire.
Most customers are comfortable buying diamonds online. Gone are the days when customers bought diamonds only from brick-and-mortar stores after seeing them in person. Today, online diamond retailers and wholesalers offer tech-savvy methods to choose and buy diamonds.
With the help of online tools, customers can easily view a diamond’s fire and performance under different types of light before they make a purchase.
