What Is a Round Brilliant Cut Moissanite?
The round brilliant cut is the most popular and technically advanced gemstone cut in the world. Designed with 58 precisely arranged facets, it is engineered to maximise light return, fire and brilliance.
In moissanite, the round brilliant cut enhances the stone’s natural refractive properties, creating exceptional sparkle and rainbow fire. This makes round brilliant moissanite one of the most sought after choices for moissanite stud earrings, engagement rings and tennis bracelets in NZ.
The History of the Round Brilliant Cut
The modern round brilliant cut was refined in the early 20th century to optimise light performance in diamonds. Its proportions were carefully calculated to reflect light back through the top of the stone rather than allowing it to escape through the sides or bottom.
When applied to moissanite, this precision cut amplifies brilliance even further due to moissanite’s higher refractive index compared to diamond.
The result is a stone that appears lively, bright and intensely radiant.
Why Round Brilliant Is Ideal for Moissanite
Moissanite has a refractive index of approximately 2.65 to 2.69, higher than diamond. This means it bends light more dramatically, producing stronger fire and sparkle.
The round brilliant cut complements these properties by:
• Maximising light return
• Enhancing symmetry and balance
• Creating consistent sparkle from every angle
• Offering timeless versatility
For this reason, round brilliant moissanite is often considered the best cut for those wanting maximum brilliance.
Round Brilliant vs Other Moissanite Cuts
Compared to oval, cushion or emerald cuts:
Round Brilliant
• Highest overall sparkle
• Most traditional and timeless
• Symmetrical and balanced appearance
Oval or Cushion
• Slightly softer silhouette
• Can appear larger face up
• Slightly less uniform sparkle
Emerald
• Step cut style
• More subtle flashes
• Emphasises clarity over fire
If maximum sparkle is your priority, round brilliant moissanite remains the leading choice.
Is Round Brilliant Moissanite Good for Stud Earrings?
Yes. The round brilliant cut is particularly well suited for moissanite stud earrings because:
• It distributes sparkle evenly across the face of the stone
• It looks proportional and balanced in small sizes
• It pairs seamlessly with both silver and gold settings
• It works beautifully in secure screw back designs
For example, a 6.5mm round brilliant moissanite is approximately 1 carat equivalent and creates a classic diamond stud appearance with enhanced fire.
