DIAMOND GUIDES
Guide to Diamond Cuts
A diamondās cut is one of the most important factors influencing its beauty, brilliance, and sparkle. More than simply the shape of a diamond, cut refers to the precision of a diamondās proportions, symmetry, and facet arrangement ā all of which determine how light travels through the stone.
At MIDAS Jewellery, we believe a beautifully cut diamond transforms exceptional craftsmanship into timeless brilliance.
What Is a Diamond Cut?
Diamond cut refers to how expertly a diamond has been shaped and polished from its original rough stone. A well-cut diamond reflects light beautifully, creating brilliance, fire, and scintillation.
Even a diamond with excellent colour and clarity can appear dull if it is poorly cut. For this reason, cut is often considered the most important of the 4Cs ā cut, colour, clarity, and carat weight.
Why Diamond Cut Matters
The quality of a diamondās cut directly affects:
- Brilliance ā the white light reflected from the diamond
- Fire ā flashes of rainbow colour
- Scintillation ā sparkle and light movement
- Overall visual beauty
When a diamond is cut with ideal proportions and symmetry, light enters the stone and reflects back through the top surface, creating exceptional radiance and sparkle.
Diamond Cut Grades
Diamond cut quality is graded based on factors such as proportions, symmetry, and polish. The most recognised grading scale includes:
Excellent
Exceptional brilliance and light performance with ideal proportions and symmetry.
Very Good
High-quality brilliance with only minor differences visible to the naked eye.
Good
Provides attractive sparkle while offering a balance between beauty and value.
Fair
Less brilliance due to light escaping through the sides or bottom of the diamond.
Poor
Noticeably reduced sparkle and overall visual appeal.
At MIDAS Jewellery, we carefully select diamonds with exceptional cut quality to ensure maximum brilliance and beauty.
Diamond Cut vs Diamond Shape
Diamond cut and diamond shape are often confused, but they are different.
- Cut refers to the craftsmanship and light performance of the diamond.
- Shape refers to the external outline or form of the stone.
Popular diamond shapes include:
- Round Brilliant
- Oval
- Pear
- Emerald
- Cushion
- Princess
- Marquise
- Radiant
- Heart
- Asscher
Each shape offers a unique personality and style while interacting differently with light.
Popular Diamond Cuts
Round Brilliant Cut
The most popular and brilliant diamond shape, featuring precise facets designed to maximise sparkle and fire. Known for timeless elegance and exceptional light reflection.
Emerald Cut
Characterised by long, open facets and a sophisticated hall-of-mirrors effect. Favoured for its refined and elegant appearance.

An elongated shape that offers brilliant sparkle while creating the illusion of greater size and length on the finger.

Pear Cut

What Determines Diamond Cut Quality?
Several factors contribute to a diamondās cut quality:
Proportions
The relationship between the diamondās depth, width, and angles determines how effectively light is reflected.
Symmetry
Perfectly aligned facets create balanced sparkle and brilliance.
Polish
A high-quality polish creates smooth, mirror-like surfaces that maximise light reflection.
Faceting
The arrangement and precision of facets influence the diamondās brilliance and fire.
How Cut Impacts Diamond Appearance
A well-cut diamond can appear:
- Brighter
- Larger
- More brilliant
- More valuable
Poorly cut diamonds may appear dull, dark, or smaller because light escapes through the bottom or sides rather than reflecting back to the eye.
This is why cut quality is often prioritised above carat weight alone when selecting a diamond.
Choosing the Right Diamond Cut
The ideal diamond cut depends on your personal style, lifestyle, and design preferences. Consider:
- Desired sparkle level
- Preferred shape
- Ring setting style
- Finger shape and size
- Budget
