Let’s Learn About Diamonds- Fundamentals Of Diamond Grading

Silver Jewellery

The most important perquisites for achieving maximum precision in diamond grading include:

→ Precise and standardized terminology and descriptive norms.

→ A well-graduated colour comparison set.

→ A series of proven practical techniques as well as knowledge in the use of equipment and technical aids.

→ Includes thorough cleaning of the stone before work starts, so that you can determine with certainty whether you have dust on the surface or interior inclusions.

→ A great deal of practical experience. Training must be underpinned with experience and knowledge.

→ Good eyesight is the most important and most valuable grading instrument required to observe the most minute characteristics, using either loupe or microscope magnification, to distinguish the slightest     colour nuances.

→ Patience is another very important personal trait that makes a good grader!

Especially at the begging, grading even one brilliant can easily last up to one hour.

In a gemmological laboratory with experienced professional graders who grade diamonds on daily basis, 20 stones every day means around 20 minutes per stone, which is a good work quota.diamond


→ Objectivity

→ Integrity

→ A sense of responsibility

→ Concentration

→ Stamina

→ Attentiveness

Today at the world’s leading diamond laboratories, several graders acting independently of one another working on the anonymity principle and having no knowledge of the client, are always used to perform colour, clarity and cut grading. The certificate is only issued after several experienced graders have come to the same conclusion.

In addition, internal tests, so-called “series tests”, are conducted on a regular basis.

These tests are performed on a series of test diamonds, which are handled in the same way as stones for other clients and which are subjected to exactly the same evaluation procedure. The graders of course do not know that the stones are being evaluated for test purpose.

These “series tests”, which are always performed on the same series of diamonds, are performed regularly. The objective is to check whether over a period of several years graders arrive at a different rating of the same diamond due, for example, to impaired eyesight or declining powers of concentration.

In other words, a diamond that has already been graded should be given the same quality rating when it is graded, again by the same individual.

Everything You Need To Know About Diamond Setting Types For The Engagement Ring

Master jewellers use multiple setting techniques to secure the gems in gold or silver. The setting can enhance the beauty of a diamond or ruin it altogether, so you need to pay lots of attention to settings. When the piece of jewellery is the engagement ring, you have to know that 10% of the price of the ring is given by the setting. This is also valid for other diamond jewellery, so here is a guide on setting types, which is going to surprise you.

One or three pieces – shopping for your love
When you are shopping for a mounting, which is the jewellery shape without the diamond in place, you need to take into account other pieces of jewellery. You may want to offer your special one a complete set of diamond earrings and diamond ring or buy the entire wedding attire in terms of jewellery: the engagement ring and the two wedding bands. Depending on this factor, you can think on how to match or stack the pieces and how frequently they will be worn.

Match the jewellery with your budget
Shopping for an engagement ring or a set of jewellery is not meant to drain your pockets. Before you go out and search for a piece, set your maximum budget and stick to it. If you have a small budget for this type of items, you can pick a single engagement ring with one small stone, and then add matching pieces to it, when your budget increases. The initial ring can be then accompanied by diamond earrings, diamond pendants or bracelets.

Another way to enhance the first investment is to add more diamonds to it, when you afford this adjustment. Of course, the setting must allow these tweaks, so always make sure you speak up your intentions to the jeweller.

The Prong setting
This is the most common type of diamond setting; the stone is being kept in place by three to six metal “claws”. This type of setting is the one seen at classic engagement rings, but it’s also used at diamond earrings or other types of jewellery. The prongs can be shaped in many ways, from flat to round and pointed or V-shaped. The bottom of the stone is being held into a special indent in the metal, called “basket”. The few prongs, the better the view on the stone, but for safety you want more “claws”. However, small stones go best with fewer prongs.

Bezel setting
The bezel setting is common in rings, opposed to the more versatile prong, which can be used on diamond earrings as well. A metal rim surrounds the stone, protecting it from being nicked and securing it to the ring. When you pick this setting you need to be aware the metal colour is going to alter the diamond colour.

Channel and bar channel settings
These settings are popular for wedding bands and complex diamond pendants. The channel setting simply secures the diamond row with two metal channels for a part or the entire ring. There could be one or two stone rows, without any metal between them.

The bar channel is a variation of the previous setting where the diamonds are secured in place with two vertical metal walls on both sides. With these methods, round stones are easier to set, thus you can notice a difference in costs.

Pave, the French-inspired setting
The word pave comes from French and it means paved, which is about how the stones are being secured in place. Three or more rows of small stones are fitted into their basket, and then surrounded in place with metal. The result is a nice “pavement” of tiny stones and colour-matching metal: silver or platinum.
