What is the crown height of Asscher Moissanite?

When it comes to the world of gemstones, Asscher Moissanite is a name that has been gaining significant traction. As a leading supplier of Asscher Moissanite, I am often asked about various technical aspects of this beautiful gemstone. One question that frequently comes up is, "What is the crown height of Asscher Moissanite?" In this blog post, I will delve into the concept of crown height, its importance, and how it relates to Asscher Moissanite.

Understanding the Basics of Asscher Moissanite

Before we dive into the details of crown height, let's first understand what Asscher Moissanite is. Asscher Moissanite is a type of moissanite that is cut in the Asscher shape. The Asscher cut is a step - cut diamond shape that was originally developed in the early 20th century by the Asscher brothers. It is characterized by its square or rectangular shape with cropped corners and a high - stepped pavilion and crown.

Moissanite itself is a gemstone composed of silicon carbide. It was first discovered in a meteor crater in Arizona in 1893 by Henri Moissan, after whom the gemstone is named. Moissanite has several properties that make it an attractive alternative to diamonds. It has a high refractive index, which means it can disperse light in a way that creates a beautiful sparkle. It is also very hard, with a Mohs hardness of 9.25, making it durable enough for everyday wear.

What is Crown Height?

In the context of gemstone cutting, the crown is the upper part of the gemstone, located above the girdle (the widest part of the gem). The crown height refers to the vertical distance from the girdle to the table (the flat top surface of the gem). Crown height is an important factor in gemstone cutting as it affects the gemstone's appearance, including its brilliance, fire, and scintillation.

Brilliance refers to the white light reflected from the surface and interior of the gemstone. Fire is the dispersion of white light into the colors of the spectrum, similar to a rainbow. Scintillation is the sparkle or flashes of light that are seen when the gemstone is moved. The crown height plays a crucial role in determining how light enters and exits the gemstone, thus influencing these optical properties.

Crown Height in Asscher Moissanite

For Asscher Moissanite, the crown height is a critical aspect of its cut quality. A well - proportioned crown height can enhance the gemstone's beauty and value. The ideal crown height for Asscher Moissanite can vary depending on several factors, including the size of the gemstone and the desired optical effect.

In general, a crown height that is too low may cause light to leak out of the sides of the gemstone, resulting in reduced brilliance. On the other hand, a crown height that is too high can cause light to escape through the bottom of the gemstone, also leading to a loss of brilliance. Therefore, finding the right balance is essential.

Most Asscher Moissanite stones are cut with a crown height that is around 12% - 16% of the gemstone's total depth. This range is considered to be optimal for achieving a good balance between brilliance, fire, and scintillation. However, it's important to note that these are general guidelines, and the actual crown height may vary slightly depending on the specific characteristics of each individual gemstone.

The Impact of Crown Height on Asscher Moissanite's Appearance

As mentioned earlier, the crown height has a significant impact on Asscher Moissanite's appearance. A well - cut crown height can maximize the gemstone's brilliance. When light enters the gemstone through the table, it is reflected and refracted within the gem. If the crown height is properly proportioned, the light will be redirected back to the viewer's eye, creating a bright and sparkling appearance.

The crown height also affects the fire of the Asscher Moissanite. A crown with the right height can ensure that the light is dispersed in a way that creates a beautiful display of colors. This is because the angle at which the light enters and exits the gemstone is crucial for the dispersion of light into its spectral colors.

Scintillation is another aspect that is influenced by the crown height. When the gemstone is moved, the light interacts with the facets of the crown, creating flashes of light. A well - cut crown can enhance this effect, making the Asscher Moissanite appear more lively and eye - catching.

Comparing Asscher Moissanite with Other Shapes

When comparing Asscher Moissanite with other fancy - shaped moissanites, such as Pear Cut Moissanite and Crushed Ice Oval Diamond Moissanite, the crown height requirements may differ. Each shape has its own unique characteristics and optical properties, and the crown height is adjusted accordingly to optimize these properties.

For example, the pear - cut moissanite has a more elongated shape, and its crown height may be adjusted to ensure that the light is properly reflected and refracted along the length of the gemstone. The crushed ice oval diamond moissanite, with its unique "crushed ice" effect, may also have a different crown height to enhance the sparkle and light play associated with this style.
