Asscher Shape Diamond Engagement Rings

A diamond cut which exudes vintage elegance and understated luxury. Our exquisite asscher cut diamond engagement rings are a truly sophisticated symbol of love.  Like the emerald cut, the asscher cut has an open culet (the bottom of the diamond) and a facet plan that draws the eye into the gemstone and gives it depth. This is a highly unusual design, often favoured by those with a more vintage taste, but also with a modern sense of style with its simplicity and symmetry.

Asscher diamonds are sometimes referred to as octagonal, or square emerald cuts. The squared nature of the diamond means the four lines of symmetry and diagonal corner facets draw the eye to the centre of the stone, making it an enchanting and unique diamond shape.

Asscher diamonds feature large step cut facets, producing optical properties that appear like a ‘hall of mirrors’. With its signature clipped corners, the asscher cut diamond features longer facets which give it a staircase appearance as it flashes long lines of sparkle, instead of the typical all-over sparkle.

Our collection of asscher cut diamond engagement rings are meticulously crafted by hand to the highest standards, offering exquisite quality and sparkle. We offer a choice of both lab grown diamonds that come with a full diamond grading report from the IGI, GIA or GCAL or our signature gemstone, the Ethica Diamond. 

The perfect length:width ratio for an asscher is between 1-1.04, for maximum light play and refractivity and standard asscher cut diamonds have 50-58 facets with cut corners, allowing light into the diamond and creating a 'hall of mirrors' effect.

Celebrities who have chosen an asscher diamond cut engagement ring include Jessica Alba, Gwyneth Paltrow, Kate Hudson, Sheryl Crow, Megan Fox and Kourtney Kardashian.

Today, the asscher cut diamond engagement ring is sought after by those who appreciate its unique and classic beauty. Its geometric shape and distinctive cut make it a standout choice for those looking for an engagement ring that is both elegant and timeless.

How do I choose an asscher cut diamond? 

Choosing an Asscher cut diamond involves considering several factors to ensure you get the best one possible. Here are a few tips to help you in the process:

1. Cut: The cut of the Asscher diamond is crucial as it determines its overall sparkle and brilliance. Look for a well-cut diamond with a symmetrical and even shape to ensure maximum light reflection.

2. Clarity: Asscher cut diamonds tend to highlight any flaws or inclusions due to their large, open facets. Aim for a diamond with a clarity grade of VS1 or higher to ensure minimal visible imperfections.

3. Colour: Asscher cut diamonds also tend to show more colour compared to other diamond shapes. Opt for a diamond with a colour grade of G or higher to ensure a bright and white appearance.

4. Carat weight: Choose the carat weight that suits your preferences and budget. Keep in mind that the Asscher cut tends to accentuate the diamond's size, so even a slightly smaller carat weight can appear larger.

5. Certification: It's important to buy a certified diamond from a reputable source like the GIA or IGI. This ensures that the diamond has been graded and evaluated by experts.

6. Personal preferences: Ultimately, choosing an Asscher cut diamond comes down to personal taste. Consider your preferences in terms of the diamond's shape, proportions, and overall aesthetics. Some people may prefer a more square Asscher cut, while others may prefer a more rectangular shape.

Do asscher cut diamonds have a bow tie effect?

Yes, an Asscher cut diamond can occasionally have an undesirable bow tie effect. The bow tie effect refers to a dark shadow or area that appears in the centre of some diamond cuts, including the Asscher cut. It is caused by light leakage or poor reflection within the diamond, resulting in a loss of brilliance. This dark area can detract from the overall appearance of the diamond and affect its beauty. When choosing an Asscher cut diamond, it is advisable to look for one that exhibits minimal or no bow tie effect for the best visual appeal.The severity of the bow tie effect can vary, and some diamonds may have a more pronounced bow tie while others may have a minimal or nonexistent bow tie.

What's the best ring style for an asscher cut diamond?

The best ring style for an Asscher cut diamond ultimately depends on personal preference and style. However, there are a few ring styles that tend to complement and enhance the beauty of an Asscher cut diamond:

1. Solitaire: An Asscher cut diamond looks stunning in a classic solitaire setting. The simple and clean design allows the diamond to be the centre of attention and showcases its unique shape and facets.

2. Halo: The geometric shape of an Asscher cut diamond pairs beautifully with a halo setting. A halo of smaller diamonds surrounding the centre stone enhances its brilliance and gives the ring a vintage or Art Deco-inspired look.

3. Three-stone: Placing two smaller diamonds on either side of the Asscher cut diamond creates an elegant and symmetrical three-stone ring. This style adds extra sparkle and visual interest to the ring.

4. Vintage-inspired: Asscher cut diamonds have a vintage appeal, so choosing a vintage-inspired setting can enhance their character. Look for ornate details, intricate filigree, or milgrain accents to create a vintage look.

5. Split shank: A split shank setting, where the band splits as it approaches the centre stone, can add a modern twist to an Asscher cut diamond engagement ring. This style can create a unique and contemporary look while still allowing the Asscher cut diamond to shine.

6. Bezel: A bezel setting surrounds the entire perimeter of the diamond with a metal rim, providing a secure and sleek look. This type of setting can emphasise the step-cut facets of an Asscher cut diamond and enhance its geometric shape.

7. Tapered band: A tapered band, where the width of the band gradually decreases as it approaches the centre stone, can add elegance and balance to an Asscher cut diamond ring. It creates a visually pleasing taper that draws attention to the diamond.

It's important to consider the overall style, metal choice, and personal preferences when selecting a ring style for an Asscher cut diamond. Our expert team at Ethica Diamonds can provide valuable guidance and options based on your specific requirements.

What is the history of the asscher cut?

The asscher cut diamond engagement ring has a fascinating and storied history. It all began in the early 20th century when a renowned Dutch diamond cutter, Joseph Asscher, introduced a new diamond cut that would forever change the engagement ring landscape.

In 1902, Joseph Asscher patented his eponymous diamond cut known as the asscher cut. This cut was a variation of the traditional emerald cut and featured a square shape with cropped corners and deeply cut step facets. Asscher was inspired by the Art Deco movement, which emphasised geometric shapes and clean lines.

The popularity of the asscher cut diamond engagement ring grew throughout the 1920s and 1930s. It was a favourite among the elite and glamorous, with its unique shape and brilliant facets capturing the attention and desire of many. The asscher cut became synonymous with luxury and sophistication, embodying the glamour of the Art Deco era.

Despite its initial popularity, the asscher cut diamond engagement ring faced a decline in popularity in the mid-20th century as other diamond cuts, such as the round brilliant cut diamond, gained more prominence. However, in the early 2000s, the asscher cut diamond experienced a resurgence in popularity due to its vintage charm and timeless appeal.

One of the most iconic asscher cut diamond engagement rings in history is the one worn by Elizabeth Taylor. Her husband Richard Burton presented her with a stunning 33.19-carat asscher cut diamond “Krupp Diamond.” Taylor's ring is regarded as one of the most exquisite and notable pieces of jewellery in the world.
