7 Jewelry Terms You Need to Know


Windowing is an optical phenomenon where light passes through a gemstone without undergoing refraction. It is characterized by either the observer looking through the stone at certain angles, or the presence of dark areas in the stone caused by light leakage through the window. An expertly cut stone should reflect so much light that no background is visible when viewed straight down through the top of the stone without any tilt. However, tilting the stone even slightly changes the angles of light hitting the pavilion facets, and each gemstone has a specific range of tilt brilliance. Gemstones with lower refractive indices require less tilting to exhibit windowing.


Durability refers to the capacity of a material to endure exposure to temperature and chemicals without disintegrating or being damaged. In this regard, lab grown diamond's are known for its impressive durability, particularly in comparison to other gemstones such as cubic zirconia or emerald.

Furthermore, lab grown diamonds is highly stable when subjected to diverse chemicals, solutions, and acids typically used in jewelry manufacturing and repair. Unlike less stable gemstones, it can resist damage from these substances, making it a reliable choice for use in jewelry..


Diamonds are famously known as the hardest naturally occurring substance on Earth. They score a perfect 10 on the Mohs scale of mineral hardness, which is a scale that measures the relative hardness of minerals. This means that a diamond can scratch any other material, including other gemstones and metals, making it incredibly durable.


Lab grown diamonds are renowned for their remarkable toughness and durability. They boast exceptional hardness, making them highly resistant to scratching, chipping, and abrasion. This durability ensures that lab grown diamonds maintain their pristine beauty even with daily wear and exposure to various environmental factors. Whether set in engagement rings or other jewelry pieces, lab grown diamonds symbolize lasting love and commitment while retaining their enduring brilliance and structural integrity.


Lab grown diamonds are prized for their remarkable luster, characterized by an intense and fiery brilliance. Their high refractive index and expertly cut facets create a dazzling play of light, making them captivating gemstones. These lab grown diamonds are celebrated not only for their beauty but also for their ethical and sustainable origins, making them a choice that shines both in appearance and conscience.

Brilliance & Refractive Index

The refractive index of lab grown diamonds is a defining feature that contributes to their stunning brilliance. This index measures how much light bends or refracts as it passes through the diamond. Lab grown diamonds have a high refractive index, which is even higher than that of natural diamonds. This property results in exceptional luster and a brilliant play of light within the gem, creating the dazzling sparkle and fire that diamonds are renowned for. The precise arrangement of facets on the diamond's surface further enhances its refractive capabilities, ensuring that lab grown diamonds shine with unparalleled radiance.

Fire (Dispersion)

Lab grown diamonds are celebrated for their mesmerizing fire, a dazzling display of colorful flashes that occurs when light interacts with the diamond's facets. This remarkable play of color is a result of the diamond's high dispersion, which is a measure of how much light is separated into its spectral colors as it passes through the gem. Lab grown diamonds, like their natural counterparts, possess a high dispersion that creates vivid flashes of spectral hues, adding a captivating and dynamic element to their overall brilliance. This fire, combined with their exceptional luster, makes lab grown diamonds truly enchanting and a coveted choice for jewelry connoisseurs.
