Belgian Heritage

BE PROUD OF

Belgium

Since 1447, Antwerp has been synonymous with quality diamonds and superior craftsmanship. Already then, the world’s leading diamond centre secured a well regulated market that won the absolute confidence of traders and consumers.
The Antwerp Diamond Heritage reveals the creative dynamism behind the diamond industry; unravelling the mysteries and beauty of the diamond, all of which has the makings of a compelling story.

1446

Passion for diamonds

Until the 15th century, only kings wore diamonds as a symbol of strength, courage and invincibility. Charles VII King of France broke the rules for his paramour, the very first woman to wear diamond jewellery. Crafting the Master Cut Lodewijck van Bercken, a mid-15th century diamond polisher, was said to have discovered the process of working one diamond with the aid of another and was thus credited with the invention of polishing. He was instructed by Charles the Bold to work three diamonds: the first was the famous Sancy, worn by the Sovereign. The second, a brilliant invented for Pope Sixtus IV and the third, a triangular diamond mounted in a ring that was later presented as a token of appreciation to the French King, Louis XI.

1447

A living Testament

The very first document concerning the Antwerp diamond trade is the decree against the sale of false stones of 1447 an official warning that “no one within the city of Antwerp was to buy, sell, pawn or pass on any false stones imitating diamonds, rubies, emerald or sapphires, …” Already in that time, Antwerp had secured a well regulated market which won the absolute confidence of diamond traders and consumers. Object of Desire The first diamond engagement ring was given to Mary of Burgundy by Archduke Maximilian of Austria. When Mary said “Yes” the tradition, of a diamond ring as symbol for eternal love and happiness, was born.

1515

The Rise of Antwerp

The 16th century, the golden age of Antwerp marks the rise of Antwerp as the world diamond centre. The diamond industry, established in the 15th century expanded considerably and secured a permanent position for Antwerp in the international trade.

1630

Rubens & Diamonds

Antwerp inspires. In the past decades, this prosperous city has produced many of the world’s most famous old masters, such as Rubens, Van Dyck, Jordaens and many more. Rubens had also a lifelong affair with diamonds. His treasure trove of diamonds suggested that he had more than a passing interest in all that glitters. His second wife, Helene Fourment, wore several diamonds and precious stones from Rubens’ private collection on their wedding day in 1630.

1751

The Art of Polishing

As technology progressed, the diamond polishing techniques evolved. An example of an Antwerp polishing workshop around mid-17th century depicts a hand cutter rubbing two diamonds against each other while the polisher stands near the scaif and applies oil to his brush. A third worker operates the mill. These 17th century techniques used in the Antwerp workshops still form the basis of today’s diamond polishing factories.

EXAMINATION

When registered in our lab, your diamond or jewellery will be thoroughly examined by our graders and will undergo the following steps:

WEIGHT

SCREENING

MEASUREMENT

FLUORESCENCE

COLOUR

CLARITY

CUT

The weight of a diamond is expressed in carats. One carat equals 0.2 grams or 100 points, which indicates the size. HRD Antwerp has extremely accurate scales that measure up to five figures after the decimal point.

The first step is to determine if your diamond is natural, laboratory-grown or treated. If a diamond does not pass the initial test, it will be directed to our research department to further determine its nature.

Your diamond is accurately measured in millimetres as mentioned below: minimum diameter – maximum diameter in mm x height in mm (example: 6.44 – 6.47 mm x 4.04 mm)

The fluorescence grade under long wave is mentioned in the report. For the “Natural Diamond Colour Grading Report” the fluorescence grade under short wave is also mentioned.

Most diamonds range in colour from colourless (‘D’) to tinted colour (‘Z’). The colour grade is determined by comparison with a series of master stones, the best grade being D.

All natural diamonds have traces of their growth history, which determines the diamond’s purity. In most gem-quality diamonds, these are minor internal characteristics or inclusions. The very best and rarest stones are graded ‘loupe clean’ or 'LC'.

A diamond’s cut is essential to its beauty and is a combination of craftsmanship and scientific knowledge. The right proportions, symmetry and polish create internal reflections that maximise a stone’s sparkle, brilliance and fire.

HEARTS & ARROWS DIAMONDS

LASER INSCRIPTION

SEALING

Hearts & Arrows diamonds are precisely cut round brilliants that, when examined using a special viewer, display eight hearts through the pavilion of the diamond (from below) and eight arrows through the crown of the diamond (from above). The appearance of the pattern is a strong indicator of a top-quality cut.

o inscribe diamonds with lasers, HRD Antwerp uses high-quality excimer shortwave technology. It cannot be seen with the naked eye and consequently does not affect the diamond’s physical appearance or value. Laser inscription can either be used to match your diamond and its corresponding grading report or to customise your diamond with a personalised message or logo.

Sealing guarantees that an issued grading report and the corresponding diamond belong together, and it keeps the diamond safe from oil and dirt. The HRD Antwerp sealing is tamper-proof.

Laboratory Grown Diamond Grading Report

Every diamond is tested to determine whether it is natural. If it is found to be laboratory grown, under disclosed conditions, we will issue a Laboratory Grown Diamond Grading Report, with this clear wording on the cover. Each laboratory grown diamond is laser inscribed with “LAB GROWN” and report number. The presence of the laser inscription is mentioned on the Grading Report, including a reference number and statement that the diamond has been laboratory grown. The same nomenclature as in a Natural Diamond Grading Report is used, with a detailed description of the 4Cs.
