Buying Tips for Asscher Cuts

A Guide to Asscher Cut Diamonds sparkling

When buying an Asscher cut diamond, there are several important factors to consider.

First, it’s crucial to pay attention to the clarity of the diamond, as step-cut diamonds like the Asscher cut tend to highlight any imperfections more prominently.

Next, color considerations are important, with a minimum of H color recommended for Asscher cuts.

Lastly, cut quality guidelines should be followed to ensure optimal brilliance and sparkle.

Clarity Recommendations

Let’s dive into the clarity recommendations for buying Asscher cut diamonds.

Consider these considerations while considering clarity:

  1. Clarity Grade: Look for a diamond with a clarity grade of at least VS2. This ensures that any inclusions or blemishes aren’t visible to the naked eye, giving you a beautiful and flawless appearance.
  2. Asscher Cut Diamonds: Due to the unique faceting of Asscher cuts, clarity plays a crucial role in their overall appearance. The step-cut facets of Asscher diamonds can make inclusions more noticeable, so it’s recommended to choose a higher clarity grade for these cuts.
  3. Diamond Expert: Consulting with a diamond expert can provide valuable insights and guidance when it comes to the clarity of Asscher cut diamonds. They can help you navigate the different clarity grades and assist in selecting a diamond that meets your preferences and budget.

Considering the clarity recommendations is just the first step in finding the perfect Asscher cut diamond. Now, let’s move on to the next section and explore the color considerations.

Color Considerations

Our color recommendations for buying Asscher cut diamonds start with considering a minimum of H color for the best results. Asscher cuts, similar to emerald cut diamonds, have large, open facets that allow more light to pass through, making color more visible. When it comes to asscher cut diamonds, color grade plays a significant role in the overall appearance of the stone. Choosing a higher color grade, such as G or higher, will provide a slight incremental whiteness to the diamond.

It’s also important to ensure that the color of the center diamond matches the side stones in engagement rings. For the best value, we recommend opting for an I color or better. With these color considerations in mind, let’s now move on to discussing cut quality guidelines.

Cut Quality Guidelines

For the best results when buying Asscher cuts, we recommend considering cut quality guidelines. Here are a few tips to help you find the perfect Asscher cut diamond:

  • Look for symmetry: Asscher cuts should have a symmetrical shape with straight edges and aligned facets. Check if the corners are well-defined and the facets are evenly distributed.
  • Check the table and depth percentages: 60%–68% for the table, 60%–70% for the depth. These proportions maximize light reflection and brightness. To understand more about how these percentages impact a diamond’s appearance and how they compare to other popular settings, consider exploring prong setting engagement rings, which provide valuable insights into the nuances of diamond settings.
  • Consider the length-to-width ratio: Asscher cuts typically have a ratio between 1.00 and 1.05. This ratio determines the shape and appearance of the diamond.

By following these cut quality guidelines, you can ensure that you get a stunning Asscher cut diamond with excellent sparkle and brilliance.

Now, let’s move on to the next section, where we’ll discuss setting styles for Asscher cuts.

Setting Styles for Asscher Cuts

When it comes to setting styles for Asscher cut diamonds, there are several popular ring designs to consider.

Halo settings, which surround the center Asscher diamond with smaller accent diamonds, are a popular choice for adding extra sparkle and enhancing the vintage appeal of the cut.

In addition, Asscher cut diamonds can also be beautifully showcased in solitaire settings or paired with diamond-accented bands for a more glamorous look.

However, it’s generally advised to avoid settings that obscure the corners of the Asscher cut, as this can detract from the unique shape and beauty of the diamond.

Popular Ring Designs

We can explore various popular ring designs and setting styles for Asscher cut diamonds. When it comes to designing a ring with an Asscher cut diamond, there are several options that can enhance the beauty and uniqueness of this vintage-inspired shape.

Here are three popular ring designs to consider:

  1. Art Deco-inspired settings: The Asscher cut diamond is often associated with the Art Deco era, known for its geometric shapes and intricate detailing. Art Deco-inspired settings for Asscher cut diamonds feature geometric patterns, milgrain detailing, and side stones that complement the clean lines of the diamond.
  2. Halo settings: Adding a halo of smaller diamonds around the Asscher cut diamond can enhance its brilliance and create a stunning visual impact. The halo setting not only adds sparkle but also makes the center diamond appear larger, giving it a more substantial presence on the finger.
  3. Solitaire settings: For those who prefer a more minimalist and timeless look, a solitaire setting is an excellent choice for an Asscher cut diamond. The clean lines and elegant simplicity of the solitaire setting allow the beauty of the Asscher cut diamond to take center stage.

Accent Diamonds and Bands

Let’s explore different setting styles for Asscher cuts, including accent diamonds and bands, to enhance the beauty of this vintage-inspired shape.

When it comes to accent diamonds, there are a few options that can complement the step-cut facets of the Asscher diamond. One popular choice is to surround the center Asscher diamond with smaller brilliant cut diamonds in a halo setting. This adds a touch of sparkle and creates a stunning contrast between the square shape of the Asscher diamond and the round brilliance of the accent diamonds.

Another option is to incorporate pavé diamonds on the band of the ring. This creates a continuous sparkle and adds extra elegance to the overall design.

These setting styles highlight the unique characteristics of the Asscher cut while enhancing its beauty.

In the next section, we’ll discuss some settings to avoid for Asscher cuts.

Settings to Avoid

We recommend avoiding certain setting styles for Asscher cuts to ensure the best presentation of these unique and beautiful diamonds. When it comes to setting an Asscher cut diamond, it’s important to consider the shape and facets of the stone. Here are three types of settings to avoid for Asscher cut diamonds:

  • Asscher cut diamonds have a distinct windmill pattern of facets that create a mesmerizing display of light.
  • Avoid settings that obstruct the view of the diamond’s facets, such as bezel or tension settings.
  • Opt for prong settings that allow maximum light to enter the stone and highlight its unique features.
  • Channel Settings:
  • Channel settings, in which smaller diamonds are set into a channel within the band, may not be ideal for Asscher cut diamonds.
  • The straight edges of the Asscher cut can create gaps between the channel walls, compromising the overall aesthetic.
  • Halo Settings with Small Accent Stones:
  • While halo settings can enhance the beauty of many diamond shapes, be cautious when choosing a halo setting for an Asscher cut.
  • The corners of the Asscher cut may be covered or overshadowed by small accent stones in a halo setting, diminishing the distinct shape of the diamond.

Asscher vs. Other Cuts

When comparing the Asscher cut to other diamond cuts, there are several key differences to consider.

The Asscher cut is compared to the emerald, cushion, and princess cuts.

While both the Asscher and princess cuts have a square shape, the princess cut offers more brilliance due to the alignment of its facets.

On the other hand, the Asscher cut has angled corners that create an octagonal shape, while the cushion cut is a brilliant cut with more fire and brilliance.

Each cut has its own unique characteristics and appeal, so personal preference plays a significant role in choosing the perfect diamond.

vs. Emerald

The forms of asscher and emerald cuts distinguish them. There are some important distinctions between them:

  1. Shape:
  2. Asscher cuts have a predominantly square shape with slanted corners, while emerald cuts have an elongated rectangular shape.
  3. Emerald cuts offer a bright sparkle, while asscher cuts may appear larger for the same carat weight.
  4. Brilliance and Fire:
  5. Asscher cuts are step cuts with straight facets and a larger table size, providing a unique vintage appeal and a hall of mirrors look.
  6. Emerald cuts are also step cuts, but they feature fewer facets and a larger surface area, resulting in a more elegant and understated sparkle.
  7. Personal Preference:
  8. Choosing between an asscher cut and an emerald cut ultimately depends on personal preference.
  9. Some may prefer the vintage charm and brilliance of an asscher cut, while others may prefer the larger appearance and sophisticated elegance of an emerald cut.

Both cuts have their own unique characteristics and appeal, so it’s important to consider your individual style and preferences when deciding between an asscher cut and an emerald cut diamond.

vs. Cushion

One key difference to consider when comparing Asscher cuts to other diamond cuts, such as cushion cuts, is their overall sparkle and fire.

Asscher cut diamonds are known for their unique ‘windmill’ pattern of facets, which gives them exceptional clarity and brilliance.

On the other hand, cushion-cut diamonds have a softer and more romantic appearance, with larger facets that create a beautiful play of light and shadows.

While both cuts have their own charm, Asscher cut diamonds tend to offer slightly more brilliance, while cushion cut diamonds provide a captivating display of fire.

Ultimately, the choice between Asscher and cushion cuts comes down to personal preference and the desired look you want for your diamond.

vs. Princess

We prefer the Asscher cut diamond over other cuts, such as princess cuts, because of its unique facets and vintage charm. When comparing Asscher diamonds to princess diamonds for engagement rings, there are several factors to consider:

  • Facet Alignment: Princess cuts have facets that are aligned differently, resulting in more brilliance. Asscher cuts, on the other hand, have angled corners that create an octagonal shape and a hall of mirrors look.
  • Shape: Asscher cuts have a square shape, while princess cuts have sharp, right-angled corners. It comes down to personal preference in terms of which shape is more appealing.
  • Price: Asscher cuts are generally a little more affordable than princess cuts, although the price tends to even out when considering other factors like clarity.
