The 4 C’s to keep in mind when choosing your white brilliant cut diamond

The Cut

The cut refers to the faceting proportions on the surface of a diamond and affect it’s overall appearance and quality. Cut is graded on a scale from Excellent to Poor and incorporates the diamond’s brightness, fire, scintillation, weight ratio, durability, polish, and symmetry. Kolmio uses the most skilled diamond cutters to ensure that our diamonds are precisely proportioned to reflect light and maximise brilliance.

The Colour

Traditionally the colour of a diamond reflects its value and rarity. The whiter the diamond, the higher the value and rarity. Colour grading starts at D (colourless) to Z (light yellow or brown). Traditionally “the whiter the better”, but we also love working with the most interesting, unusual colours of diamonds like, cognac, yellow and grey.

The Clarity

Virtually all diamonds have imperfections called inclusions or blemishes. The less internal features it has, the more light refracts through and the higher the value and price.


Carat Weight

A “carat” is the gemologist’s standard unit of a diamond’s weight. This factor has a great effect on the diamond price.


Unique and unusual cut diamonds

Rose Cut

The rose cut diamond dates back to the early 1500’s. Rose cuts are flat bottomed and domed shaped featuring triangular facets on the tipped crown. The rose cut diamond resembles the shape of a rose bud. It’s very commonly used in antique jewellery, but the demand for it has increased for it, as it has a unique shape. Available in an array of colours and shapes, these gems are truly something beautiful to behold. If your partner loves antique jewellery, this cut is the perfect fit for an engagement ring that will make them feel like they are walking on air! They are also available in a variety of shapes.

Unique colour

Champagne or cognac

These are gorgeous rich amber tones of diamonds. A personal favourite! These diamonds are rare and rich natural brown diamonds. Tones ranging from C1, the lighter champagne colour, to C7, the rich dark brown colour. Like the French drink, cognac, it speaks luxury and elegance. These diamonds are available in the traditional Brilliant Cut as well as the Rose Cut, in a variety of shapes.

Opaque diamonds

These diamonds usually persists of quite an amount of inclusions, making their brilliance and fire a lot different than the classic white diamond, as light refracts differently through them. These beauties are quite special. They are available in an array of colours and shades. The beauty of these diamonds is that you won’t get the exact same diamond colour ever! This diamond choice is perfect for those who like to stand out and thrives for something unique and truly amazing. Black diamonds also form part of this category, as they are not transparent.
