Single Cut vs Full Cut Diamonds: What’s the Difference and Which is Better?

Cut quality largely determines a diamond’s fire, brilliance, and scintillation. Diamonds form over billions of years under intense pressure and heat deep within the Earth, but their true beauty is revealed only after expert cutting and polishing. A diamond’s cut shapes how it reflects light, its sparkle, and brilliance.

In this guide, we’ll explore the intriguing differences between single-cut and full-cut diamonds. Knowing these unique characteristics will help you select and purchase loose diamonds for your engagement ring or piece of fine jewelry.

What Are Single-Cut Diamonds?

Single-cut diamonds, also known as 8/8 cuts, have fewer facets than most modern diamonds. Generally, they feature 16-18 facets, often split evenly with eight on the top (crown) and eight on the bottom (pavilion). This simpler faceting pattern creates a gentle sparkle and makes single cuts popular in vintage and antique-style jewelry as accent stones. 

Single-cut diamonds are predominantly cut and polished in sizes under 0.03ct or 2mm. The reason is that the facets on tiny diamonds can be so small that they cannot be resolved by the human eye, creating a “mushy” look.

What Are Full-Cut Diamonds?

Full-cut diamonds are a modern evolution of single-cut stones, taking the faceting technique to a more complex level. Full cuts, often called “round brilliant cuts,” feature 57 or 58 facets, which produce the fire and brilliance most people associate with diamonds. Each facet reflects light from multiple angles, creating a dynamic display of sparkle. This is why full-cut diamonds are a go-to choice for engagement rings, earrings, and other statement jewelry pieces.

Key Differences Between Single-Cut and Full-Cut Diamonds

While both cuts bring a unique beauty to jewelry, here are some essential distinctions to consider:

  1. Faceting: Single-cut diamonds have 16-18 facets, while full-cut diamonds have 57-58. More facets in full-cut diamonds create more sparkle. 
  2. Cost: Single-cut diamonds are typically less expensive due to their simpler faceting. Full cuts require more labor, which raises their value.
  3. Aesthetic: Single cuts offer a vintage look, perfect for antique-style pieces. Full cuts are known for their fiery brilliance, suited for modern styles.
  4. Size: Single cuts are commonly used in smaller stones (under 0.10 ct), while full cuts are available in a broader range of sizes. 

Where Are Single-Cut Diamonds Used?

Single-cut diamonds are mostly used in Swiss Watches, antique or vintage-style jewelry, as their softer sparkle complements the aesthetic of classic designs. You’ll often find them in pavé, channel, or cluster settings where their simplicity enhances rather than distracts from the center stone. Likely, because single-cut diamonds create a delicate shimmer rather than intense brilliance, they’re a great choice for accenting step-cut center stones like emerald or Asscher cuts.

Where Are Full-Cut Diamonds Used?

Full-cut diamonds are versatile and can enhance nearly any jewelry style. They are especially popular in modern jewelry designs where maximum sparkle is desired. In engagement rings, smaller full-cut diamonds often frame a center stone in a halo setting or line the band in a pavé setting. With their exceptional brilliance, full-cut diamonds bring a captivating sparkle to jewelry, making them perfect for larger stones in solitaire settings, as well as for pavé or micro-pavé accents. 

Single-Cut and Full-Cut Diamonds: Which Is Right for Your Jewelry?

Your choice between single and full-cut diamonds depends on style, jewelry design, and desired sparkle. Full cuts offer maximum brilliance and fire, ideal for center stones or designs needing extra sparkle. In contrast, single cuts give a subtle, classic beauty, perfect as accent stones in vintage or intricate settings.
