Peter George Banks Jewellers: Precious diamonds for unique moments
A diamond grading certificate or report/dossier is like a ‘fingerprint’ for the diamond, describing the stone in technical detail to verify its value and identity. It does not assign monetary value to the stone, as an appraisal does, and is only provided for loose diamonds. The report is created by a Gemmological laboratory where the diamond is evaluated, measured and graded by cut, clarity, colour and carat. A completed certificate includes an analysis of the diamond’s dimensions, polish, symmetry and other dimensions.
A certificate verifies the diamond is natural and enables you to buy your diamond with confidence. Every loose diamond supplied by Peter George Banks Jewellers has been analyzed by one of the two largest and most reputable independent laboratories in the world: Hogue Raad voor Diamant (HRD) and the Gemmological Institute of America (GIA).
4 C’s Diamond Education
A diamond is pure or nearly pure carbon, with extraordinary qualities of fire and brilliance. The factors used commonly to determine the quality and value of a diamond are known as the 4 C’s: Cut, Clarity, Colour and Carat weight.
· Diamond shapes
Cut shouldn’t be confused with shape. Shape refers to the general outward appearance of the diamond, such as marquis, oval or princess.
The term cut refers to the facets, and their proportions, on the surface of a diamond. The shape and skill of how a diamond is cut determines the sparkle. Perfect proportions mean more dazzle as it is all about catching and refracting the light. A diamond cut too deep or shallow has less sparkle than one with ideal proportions. The cut also determines the shape of a diamond and can range from the classic Round Brilliant cut to a Princess cut and more fancy cut diamonds such as; Asher, Emerald and Marquise. Quality of cut is defined as Excellent, Very Good, Fair or Poor. From exceptional fire, presence and brilliance to dull and lifeless as they lose most of the reflected light out of the sides and bottom of the stone.
The very best colour for a diamond is no colour at all, these precious stones are known as 'white diamonds'. The whiter the diamond, the greater its value and beauty. Most diamonds are graded on the GIA colour scale from D (colourless) the rarest and most valuable, down to Z (yellow) of lesser value and quality. Stones on the D-F ranges are considered the most beautiful and valuable, they are also the rarest.
Due to the pressure placed on carbon crystals when diamonds are formed tiny inclusions remain inside the diamond, often invisible to the naked eye. As diamonds refract light from the way they are cut, the ones which are free from inclusions do not interfere with the passage of light through the stone. Flawless; having no internal or external imperfections are the highest quality of diamond, extremely rare and demand the highest value. Most diamonds contain small natural inclusions, the number of these and their size in the diamond effect the clarity as shown in the chart. Clarity grades range from ‘Flawless’ (FL) or ‘Internally Flawless’ (IF) to ‘Imperfect’ (I or P).
The size of a diamond in measured in carat weight. For example one carat is 0.2 grams, this is divided into 100 points so a diamond of 75 points weighs 0.75 of a carat and a diamond of 50 points weighs 0.50 of a carat. A two-carat diamond will be worth more than two times a one-carat diamond of the same quality.

Will it fit?
For the perfect fit you will need to establish her ring size. Women usually wear dress rings on their right hand which will be a different sizing to their engagement ring finger and as such needs be taken into account. If you can ‘borrow’ a ring and either bring into us or trace around it for us to measure this would be ideal, try and remember on which finger she normally wears it. Or have a friend take her shopping and try on a few rings so they can pass over the information to you.
Setting your Budget
Diamonds are an excellent investment that will last a lifetime; they will not depreciate in value. But how much should you budget for? We recommend to spend what feels right but as a starting point it is commonly suggested that the engagement ring should cost twice the man’s monthly salary, but the ‘perfect’ ring usually chooses you so although you may have a budget in mind, prepare to be flexible. Good Jewellers have the experience to discreetly guide your lady away from a ring which is outside your budget, which is why it’s a good idea to use our private viewing service. You can make an appointment or phone ahead giving us an indication of your preferred and upper limit budgets and discuss comfortable payment options to avoid disappointment or embarrassment.
For those unique moments in life, trust Peter George Banks Jewellers. We won't let you down.
A Brief History of Diamonds
Diamonds, from the Greek, adàmas, (archaic root word of adamant) meaning unbreakable, are the hardest substance of carbon allotropes, some 99.95% pure crystallized carbon formed beneath the Earth’s surface when crystals of diamond occur in volcano feed pipes. It was discovered roughly around 3000 years ago, in Central Asia. Experts surmise that it could have been used as early as 6000 years ago. Recent finds indicate that the Chinese have been using them around 2500 BCE or later, although no sufficient evidence is enough to rewrite the decreed historical data.
Official records state that, around 800 BCE, Indians had made one of the most important discoveries of the ancient world; the discovery of the diamond. Although used largely for decorative purposes and somewhat spiritual by nature, the diamond has been used for polishing stone axes and as a tool to help fine-tune and polish weapons, due to its hardness.
It was only during the Greco-Roman era that diamonds became a rare medium for trade, gradually became one of the many symbols for luxury in an era aside from its supposed magical properties.
The myth of the diamonds having supernatural qualities survived well through the passage of years, after the fall of The Western Roman Empire and through to the Byzantine era. However, it was only during these times, in the dark years of the Middle Ages, that the diamond began to have a reputation for possessing evil effects. Miners, who were well aware of the myths of vitality-imbued characteristics of the gemstone, began stealing the jewels by swallowing them in small amounts. This led to the rumor injected by mining owners to discourage the theft of the valuables. They disseminated the rumor that the diamonds were poisonous and required spiritual guidance and almost divine intervention to reverse the side effects.
As the years passed and into the renaissance period, the mining consortiums of India began to experience a salient decline in its production of diamonds as demand began to increase. Even other mining syndicates around the world could not keep up with the ever-increasing need for diamonds. It was only when in South Africa, during the proto-industrial age, large deposits of the precious commodity were discovered, that the world’s largest diamond rush began.
Diamonds spread all over the world, especially in gifts for royalty and very wealthy people. It took many centuries before India dried up its main resources for diamonds which led to exploration around the world for more mines. This exploration brought on major diamond mine discoveries in both Brazil and South Africa. Since then South Africa has become the largest producer of diamonds in the world. Unfortunately we all have heard about the troubles this trade has brought to the people of Africa, but no matter what it continues onward.
Diamonds have been traded and sold for thousands of years but not too many people know how and where they got their start in the jewellery trade. Diamonds are not only found in wedding rings, necklaces and earrings, but now they're placed on cell phones, cars and even clothing.
Belgium jewellers, specifically Antwerp, made a name for themselves for developing a new technique to polish and shape the gems was created. Since then Belgium has become the diamond center of the world with more than 12,000 expert cutters and polishers at work. You'll find today that 85% of the world’s rough diamonds, 50% of cut diamonds, and 40% of industrial diamonds are traded in Antwerp year round.
