Why CBI Diamonds?

 

Paramount quality

CBI produces the highest quality diamond cuts, engaging their passion and expertise to enhance all the natural assets of a diamond, making your diamond appear bigger, white and cleaner than diamonds of identical carat, colour and clarity.

Investment in the future

Exceeding known metrics, CBI diamonds are cut with the future in mind. Current internationally agreed cut grades are wide, allowing for enormous variation. With advances in technology and consumer knowledge the experts at CBI see a future where cut will be reported in finer detail meaning truly excellent cuts and high-performance diamonds are elevated in value above diamonds currently achieving the very minimum standards for the grade.

Exclusivity

Stepping away from the modern demands of mass production, CBI produces a limited stock of just 1000 diamonds a year, allowing them to prioritise precision and consistency above all else.

About CBI

CBI are trailblazers in diamond cut

CBI produce diamonds which use advanced technology and expert knowledge to maximise their visible carat, colour and clarity.

CBI look beyond the certificate

They are leaders in diamond cutting and education and have developed their own, regimented standards which prioritise diamond performance and consistency.

From fine beginnings

At CBI they know that the best quality cut diamonds can only be achieved with the best quality source material. The uncompromising standards of a CBI diamond promises high performance and consistency, guaranteed to give your diamond superior scintillation, dispersion, brightness and contrast

Rarity vs Quality

When assessing diamonds, the universally accepted grading system takes into account the Four Cs <link> but these can be separated into two value factors. A diamond’s rarity and diamond’s quality.

Rarity

When assessing diamonds, the universally accepted grading system takes into account the Four Cs <link> but these can be separated into two value factors; a diamond’s rarity and diamond’s quality. Rarity describes the fixed and unchangeable characteristics of a diamond. Diamonds of high size, colour and clarity command high prices because these characteristics are rare.

Quality

When it comes to cut, the level of quality is in our hands. Cut is dictated by the technology, skill and passion of the diamond cutter. The joy or disappointment experienced when looking at your diamond can be a direct result of just how expertly it was cut.

Brightness

Finely cut diamonds tend to appear BRIGHT in a broad variety of lighting environments.

Fire

Fine makes tend to exhibit large amounts of FIRE when illuminated in fire-friendly lighting environments.

 

Leakage

Fine makes do not have excessively large areas of light LEAKAGE.

Contrast

Fine makes will have enough dark/light CONTRAST to be interesting, but not too much dark as to impact the brightness of the stone.

Proportion factors

Weight Ratio. Finely cut diamonds achieve a high level of performance without using excessive weight.

Durability. Fine makes are resistant to chipping.

Tilt. Fine makes do not exhibit the “fish-eye” effect.

Girdle. Fine makes do not have excessively thin or thick girdles, mostly due to durability/weight ratio concerns.

Culet. Fine makes do not have an excessively large culet.

Finish factors

Polish. Finely cut diamonds should have a polish which does not interfere with light return. 

Symmetry. A finely cut diamond should have perfectly aligned and shaped facets. Traditional diamond grading reports on the average symmetry throughout the stone. Not satisfied with this CBI makes sure that every individual facet is cut to their exacting standards. 

CBI Diamonds FAQ

 

Are CBI diamonds more expensive than normal diamonds?

CBI makes no apologies for the small premium required to invest in one of their diamonds. CBI diamonds use the finest starting material, the most highly skilled cutters and most advanced technology, prioritising cut results throughout. Executing the calculated designs of their diamonds also means that they yield less carat weight from a rough diamond compared to an inferior cut, which makes the process of creating perfection more costly.

Are CBI diamonds a good investment?

Investment diamonds make up a very small proportion of diamonds traded and when creating an engagement ring, investment should never be a primary consideration. You’re probably looking to create an engagement ring as a symbol of love and commitment, not with the intention of selling it down the line. 

What’s the difference between CBI and Excellent/ Ideal cut diamonds?

Looking beyond a diamond certificate, CBI diamonds give you the security that your stone has been cut to a refined set of standards. Of the diamonds which are graded as Excellent even by a reputable grading laboratory, you can expect there to be significant and visible variation in light performance due to the wide guidance of this criteria. Until grading laboratories report on brightness, fire, leakage and contrast, choosing a specialist diamond from a brand committed to high performance is your best guarantee.

Why don’t diamond certificates report on light performance?

The cynical answer would be because they don’t want to. Diamonds have historically been cut to enhance their value according to a set of goal posts dictated by existing diamond grading criteria. If grading laboratories alter the criteria for cut it would mean that stocks of diamonds currently classified as the best possible cut, could be downgraded at a financial loss. A less cynical answer could be that certificates just don’t report on light performance yet. Growing markets such as China have already seen the demand for higher performing diamonds and as the market evolves reporting should catch up.

Select the perfect diamond shape for you. Round Brilliant diamonds are undoubtedly the most popular for their fire and sparkle but if you are looking for the variety and character of a fancy shape then see what else is available.
The size that suits your design, your taste and your budget. Carat weight refers to how heavy a diamond is. It is indicator of the size of the diamonds, however, you should refer to the measurements of the stone to get like for like comparisons.
The quality of a diamonds is arguably all about cut. An Excellent cut diamond will be fashioned so that it’s proportions, symmetry and polish result in superb brilliance, fire and sparkle. 
White diamonds are graded by how colourless they are in appearance. D-F are Colourless, G-I are Near Colourless and K-Z are Tinted. The difference between each colour grading is slight and saving on colour can free up spending on the other Four Cs.
Clarity is an assessment of the number and position of visible inclusions in a diamond. For some shapes such as Emerald cut diamonds clarity is key, while for other more brilliant cuts, inclusions can become less noticeable.

Clarity is graded using the following abbreviations: IF/F meaning Internally flawless/ Flawless, VVS meaning Very Very Slightly included, VS meaning very slightly included, SI meaning Slightly Included and I is Included.

Polish grading is a recognition of how finely a diamond cut was finished. A diamonds Polish should enhance the cut by not interfering with light return.
Diamonds cuts are carefully calculated and planned for optimum light performance and beauty. The facets in a diamond should be perfectly aligned and shaped. 
The depth of a diamond will impact the light performance and appearance of size. If a diamond is deep a lot of it’s carat weight will be ‘hidden’ beneath the stone where it can’t be enjoyed and the diamond will look smaller. Depth of a diamond also impacts light performance and a diamond that is too deep or too shallow will leak light.
The table needs to be well balanced to the proportions of the diamond. For a Round Brilliant diamond, the table should be around 54% – 57%
Fluorescence is the phenomenon in a diamond that causes a stone to produce a colour reaction (usually blue) in response to ultraviolet light. ‘Strong fluorescence’ is generally avoided as it can make a diamond appear hazy, however in some instances, faint blue fluorescence can improve the appearance of a diamond with low colour, in making it look whiter in daylight.
Our diamonds above 0.30ct will come with certification from an independent, reputable diamond grading laboratory. These include The American Gem Society (AGC), the Gemological Institute of America (GIA) and the International Gemological Institute (IGI)
Choose any special criteria for your diamond; Crafted by Infinity (CBI) for their impeccable cut quality, Mined diamonds from the Earth, Canadian diamonds with guaranteed provenance, or Lab Grown diamonds taking advantage of cutting edge technological developments.
Length-Width ratio of a fancy shaped diamond can be a matter what suits your personal taste and the ring design but it can also impact the beauty of the stone. Ideal ratios for different fancy shaped diamonds include Emerald diamonds = 1.34 – 1.43, Oval diamonds = 1.35 – 1.45, Pear diamonds = 1.47-1.65 and Marquise diamonds = 1.90 – 2.10
