Octagon Cut Diamond: Eight-Sided Brilliance and Structured Sophistication

The octagon cut diamond is making waves in the luxury jewelry world, captivating engagement ring shoppers, collectors, and fashion-forward buyers alike. As its name suggests, this rare geometric diamond cut boasts eight polished sides that create a mesmerizing shape unlike any traditional round or square stone. The result is a diamond that exudes both vintage charm and modern flair – a true embodiment of structured sophistication. In this article, we’ll explore what an octagon cut diamond is, why it’s uniquely appealing, and how Mikado Diamonds embraces this elegant, uncommon cut in our collections.

What Is an Octagon Cut Diamond?

Simply put, an octagon cut diamond is a diamond shaped with eight sides when viewed from above. This gives the stone a distinctive outline resembling an octagon (imagine a stop-sign shape, but glittering). In many ways, the octagon cut offers a contemporary twist on the classic round brilliant. It is cut by expert gem artisans to maximize light return, often featuring more facets than a standard round diamond. Those extra facets and the symmetrical eight-sided form yield incredible fire and sparkle, even under low light conditions.

Notably, octagon cut diamonds are similar in brilliance to round cuts but with a bolder, angular silhouette. From the crown (top) view, you can see crisp edges and broad facets that act like mirrors – creating a kaleidoscopic play of light. This shape is the only diamond cut with eight equal sides, and its unique geometry gives it a shine and character all its own. According to some jewelry experts, octagon diamonds are a relatively new entry to the diamond world, designed to stand out for their crisp, symmetrical form and high-performing sparkle. Because they require precise cutting, they have historically been uncommon – until recently mostly appearing in specialty lab-grown diamonds where cutters have more flexibility to experiment.

Why Choose an Eight-Sided Shape?

If you’re drawn to the octagonal diamond shape, you’re in good company. This cut has been gaining attention among trend-conscious buyers for several compelling reasons. Here are a few of the top appeals of an octagon cut diamond:

• Unique Style & Elegance: An octagon cut diamond immediately stands out. It’s uncommon and eye-catching, perfect for those who want a ring that doesn’t look like everyone else’s. The eight-sided shape strikes a balance between classic and modern – offering a nod to Art Deco geometry while remaining sleek and contemporary. In a solitaire ring, an octagonal diamond becomes a conversation piece, radiating unique elegance.
  
  
• Symbolism & Meaning: The number eight carries special meaning in many cultures. In Chinese and other Asian traditions, eight is considered a harbinger of good fortune. The octagon shape is also linked to renewal and infinity – its resemblance to the figure-eight symbolizes enduring love and rebirth. For an engagement ring, these sentiments add romantic significance. An octagonal diamond ring can thus signify eternal commitment, luck, and a prosperous union all at once.
  
  
• Brilliance & Sparkle: Octagon cut diamonds are engineered for brilliance. With their many facets and symmetry, they deliver outstanding fire – rivaling even rounds in sparkle. In fact, the broad facet arrangement often creates a “starburst” effect of light. Wearers love that this cut shines brightly even in dim lighting, meaning your diamond catches eyes day or night. It’s a dazzling choice for those who refuse to compromise on sparkle.
  
  
• Secure & Practical: The eight-sided shape isn’t just beautiful – it’s also quite practical. Unlike shapes with sharp points (like marquise or princess cuts), the octagon’s corners are cropped, which can make it less prone to chipping. Moreover, jewelers note that octagon diamonds tend to sit securely in prong settings. The evenly angled sides allow prongs to grip snugly, so an octagon cut stone is held more securely in a ring – ideal for someone with an active lifestyle. You can enjoy a bold look without worrying about daily wear as much.
  
  

In essence, choosing an eight-sided diamond means embracing a shape that marries meaningful symbolism, modern style, and superb brilliance. It’s perfect for the individualist who appreciates both beauty and deeper significance in their jewelry.

Mikado Diamonds and Structured Sophistication

At Mikado Diamonds, we believe that every jewelry piece should tell a story – and an octagon cut diamond tells a story of structured sophistication like no other. Our design philosophy blends time-honored craftsmanship with contemporary design, and the octagonal cut fits this ethos beautifully. The clean geometry of an octagon diamond adds a distinct architectural elegance to rings, earrings, or pendants, aligning with Mikado’s commitment to elegant yet uncommon designs.

Quality and Variety: Despite being relatively rare in the market (the octagon cut is still new and limited in availability), Mikado Diamonds offers a curated selection of these extraordinary stones. You can find octagon cut diamonds in both natural and lab-grown varieties through our collection. For example, we have sourced exquisite natural octagon diamonds like a 0.78 ct H/SI2 octagonal diamond (GIA certified) that would make a stunning centerpiece for a custom ring. If you desire a larger or more affordable option, lab-grown octagon diamonds are available as well – such as a dazzling 3.04 ct E/VVS2 octagonal lab-grown diamond with excellent symmetry and polish. Each of these stones is hand-selected to meet our strict standards of cut and quality.

Design Your Dream Ring: One of the hallmarks of Mikado Diamonds is our bespoke approach. Many clients choose an octagon cut diamond to create one-of-a-kind rings that reflect their personal style. Whether set in a vintage-inspired halo or a sleek modern solitaire, an octagonal diamond brings a structured, architectural look that elevates the design. Our jewelers can craft settings that protect the eight corners (for instance, using a bezel or halo can both showcase the shape and guard it, marrying style with security) while letting the stone’s brilliance take center stage. The octagon cut’s versatility shines here – it looks just as breathtaking in a classic platinum setting as it does in an ornate antique-style design. Mikado’s wide array of setting choices (we boast one of the largest selections of ring settings) means your octagon diamond ring will be perfectly yours.
