Diamond

A few facts about the diamond:

The diamond consists of carbon which is formed in the intermagmatic phase in the earth's crust due to extremely high temperatures and extremely high pressure. It is the hardest known material* (on the Mohs' scratch hardness scale) and therefore absolutely suitable for everyday use.
*(I've heard of a snail whose teeth should be harder than diamond, but I haven't researched it yet and don't know if it's so important here?)

The diamond is the natural gemstone with the most clearly defined quality graduation.

The advantage is that it makes the comparison very easy for you as a customer.

The disadvantage is that this beautiful gemstone is almost only offered in standard cuts, and thus somehow one looks like the other.

The criteria are the so-called "5 C".


1. Clarity: the degree of purity
refers to visible inclusions at 10x magnification:

  • if = internal flawless = flawless
  • vvsi= very, very, small inclusions
  • vsi= very small inclusions
  • si= small inclusions
  • Piquee I = small inclusions visible to the naked eye
  • Piquee II = inclusions visible to the naked eye
  • Piquee III = large inclusions visible to the naked eye.


2. Color: 

  • River (D/E) = very fine white
  • Top Wesselton (F/G) = fine white Wesselton (H) = white
  • Top Crystal (I) = lightly tinted white Crystal (J) = tinted white
  • Yellow I (K/L) = light yellow cast 
  • Yellow II (M-Z) = yellow cast


Then there are the so-called "fancy colours". These are coloured diamonds, e.g. pink, champagne, blue, green, yellow, etc.... These must be clearly recognizable as coloured from a distance.

3. Cut:
The most common shape for diamonds is the brilliant cut.
The brilliant cut is a standardized round cut with 56 facets. But of course you can also get the diamond in all kinds of other shapes, e.g. Princesscut, Emerald- or Asshercut, Navette, Heart, Drops or in free fantasy cuts.

4. Carat: the weight
the size is given as weight in carat. Carat is an ancient weight unit and refers to the seeds of the carob tree. One carat corresponds to 0.2g.

5. Confidence: Trust
Applies to conflict-free diamonds from certified sources.
On the one hand this is a question of origin, on the other hand it is a question of further processing.
It is possible that a stone from a trustworthy source costs a few euros more, but you can also be sure that you will not get  a gem produced inchild labour or get a so-called "blood diamond".

Diamonds are the most popular gemstones for engagement rings, but it doesn't always have to be the white diamond. There are diamonds in many wonderful cuts and even the "Fancy"- Colors can be stunningly beautiful!
 

Diamond Certificates



Often diamond jewellery is offered with certificates.

There are GIA, IDC, CIBJO, .... But what does that actually mean?

As mentioned above, the diamond is the natural gemstone with the most clearly defined quality graduations. These criteria have evolved over time, and at some point various organizations have sat down and set certain standards for graduation.

This means, for example, that a GIA certificate is a certificate that was issued according to the rules of the Gemmological Institute of America, or an IDC certificate was issued according to the rules of the International Diamond Council.

It does not mean, however, that the certificate was issued by these institutions!

Usually it is the diamond traders who create the certificate.
However, some jewellery producers have also hired their own diamond graduates.

When a certificate is issued, an "identity card" is issued for the individual stone.

The stone is examined for the criteria listed above, colour and cut are compared with the standard and inclusions are recorded.

The preparation of a certificate, if done correctly, is very time-consuming and only worthwhile for larger stones (from approx. 0.25 ct.).

Of course, there are also superordinate institutes that completely independently assess and graduate gemstones of any kind.
However, this is connected with relatively high costs and makes therefore only with really valuable gemstones at all sense.

Trust is a very important basis in the jewellery industry. As a goldsmith, I only work with trustworthy, small dealers.
I want to know where the stones come from, who processes and graduates them.

Always remember: a certificate depends on who issues it!
