Gold purchase


The problem of testing gold jewellery

Authenticating gold jewellery is a major challenge. Due to the very diverse geometries (rings, necklaces and ear studs, etc.) and the composition (different mixed gold alloys in different carats), it is impossible to determine gold jewellery exactly using only one test method. The most common types of counterfeit jewellery are

  • Counterfeit jewellery with base metals: This refers to the plating of a base metal with gold. This often occurs with rings or chains made of tungsten or tungsten carbide, whereby these materials almost perfectly imitate the density and thus the “heavy feeling” and feel of real gold jewellery.
  • Under-alloying / hallmark fraud: If the gold content of an alloy is lower than specified by the hallmark.
  • This can also be done in an even more sophisticated way, in that the surface of the piece of jewellery has the correct alloy and the underlying material is worthless foreign material or an inferior alloy.

Due to the large number of different types of gold alloys and jewellery geometries, the testing of jewellery is more demanding than that of gold bars, for example. The following testing methods should therefore be available when purchasing jewellery.

1. magnetic scale "MagneticScreenScale "
A sustainable method for measuring bars and coins is to determine the so-called magnetic susceptibility properties. This makes it possible to determine, even through blister packs and packaging up to a certain thickness, whether the material applied has the correct magnetic behaviour - para- or diamagnetic, i.e. attractive or repulsive. A so-called “tungsten detector” can be used to determine the presence of a potential foreign body: a gold bar as a so-called diamagnet displaces a magnetic field, creating pressure on the measuring head of the scale and displaying a positive value. If a supposedly genuine fine gold bar is placed on the scale and a negative value appears, it is in most cases a fake.

2. density scale "DensityScreenScale "
You can use the density scales to quickly and precisely determine the density of all types of materials. It is equally suitable for analysing bars and gold jewellery to determine their purity and alloy composition and to determine bars or jewellery that have been “stretched” or under-alloyed with silver or copper. The density is determined using the tried and tested method of Archimedes: To do this, the object is weighed with a sieve under water and once “normally”. The density can be determined directly from the two different values. This gives you an insight into the quality and carat of the gold or even an initial indication of the possible presence of forgeries. Determining the authenticity and gold content of geometrically irregular objects such as jewellery is therefore no problem.

3. surface testing with test acids or X-ray fluorescence analysis

  • The gold coating sample with test acids: In principle, the first, relatively simple and cost-effective step is to determine the gold content using gold test acids.
  • X-ray fluorescence analysis (XRF): This determines the exact elemental composition of the jewellery on the surface. This method is very expensive (approx. 15,000 - 45,000 EUR) and is purely superficial: the maximum penetration depth is only 0.010 mm.

Electrochemical testing using the "CaratScreenPen ".
The CaratScreenPen uses an electrochemical process to determine the purity and fine gold content on the surface of gold and platinum jewellery. The measuring tip forms a so-called “galvanic cell” on contact with the object lying on the measuring surface. This results in a certain electrochemical behaviour, which is registered by the measuring tip and processed by the device.

The complete and detailed article on the methods of gold testing can be found here:

leather straps


Manufacturing techniques for watch straps

What does cut strap actually mean and what are the differences to a fully remborded or semi-remborded leather strap?

What characterises a leather strap “Made in Gemany” and how many work steps are required for this?

Cut strap (approx. 70 work steps)

The cut strap is the most common, but rather simple leather strap. It consists of a three-layer material - upper leather, filling material and lining leather. The leather is cut by using a cutting tool and the edges are then varnished.

With around 70 work steps, it is somewhat more complex to produce than the semi-remborded leather strap.

Semi-remborded or semi-crowned leather strap (approx. 50 work steps)

With the semi-remborded strap, the upper leather surrounds the body of the strap and the lining leather forms the end at the bottom. In contrast to the full remborded strap, the upper leather is not covered and sewn under the lining leather. It is therefore not the seam that holds the strap together but, as with the cut strap, only the adhesive. Due to the durability is this the optimal production method as it shows no open edges.

This production method could only be implemented with modern, environmentally friendly adhesives and the only approximately 50 work steps have lead to economical consumer prices.

Remborded or full wraparound finish leather strap (approx. 100-120 work steps)

With the full remborded leather strap, the upper leather is wrapped around the filling material and sealed from the lining leather by adhesion. On the inside of the leather strap is a breathable filling material which leads to a better ventilation effect (“aero lining”). All the layers are glued with each other. A thread is only a design feature. Semi- and fully remborded leather straps combine softness - depending on the upper leather - with high stability and durability.

With approx. 100-120 work steps, it is quite complex to produce, which is why it is preferably used for high-quality bracelets.

Welding Workshop


Weekend seminar on 27.04. and 28.04.2024 the PUK fine welding was a complete success!

The latest fine welding technology was the topic of the ‘PUK 6’ seminar, which took place again at the premises of Gebrüder Boley after a five-year absence. In cooperation with Lampert Werktechnik, we succeeded in organising another workshop on PUK fine welding after May 2019. The participants took the opportunity to test the handling and results of the latest generation of PUK 6 devices on fine welding machines.

The 2-day seminar took place this weekend on Saturday, 27 April and Sunday, 28 April 2024 under the direction of Susanne Englert, a trained master silversmith and teacher at the “Staatliche Zeichenakademie” in Hanau.

The participants were introduced to the PUK welding technique on both days on the following welding topics:

  • Application of metals
  • Welding silver
  • Carrying out ring changes
  • Welding ear studs
  • Welding of settings
  • Fixation welding
  • Treatment of individual special applications
  • and much more.

The participants had brought their own jewellery and watch pieces with them. Mrs Englert was able to use these as examples to work out solutions to problems for all participants and thus provide important tips for everyday workshop work. The focus was also on the exchange of experiences between the participants.

The participants spoke of a very successful seminar, which will be offered again in this form by Gebrüder Boley at regular intervals. We would like to take this opportunity to thank all participants and especially Mrs Susanne Englert for her participation and commitment.

Labgrown diomonds

The Difference


NATURAL VERSUS LAB-GROWN DIAMONDS

Did you know that there is one important difference between natural and lab-grown diamonds? Natural diamonds can contain nitrogen atoms or aggregates. Nitrogen is one of the most common impurity elements in natural diamonds and can affect their color and properties. The presence of nitrogen can lead to a yellow or blue color in the diamond. However, there are also diamonds that are almost free of nitrogen and are therefore colorless or of high purity. However, these diamonds make up only 1.8% of all natural diamonds. The laboratory-grown diamonds are either grown under high temperature and high pressure (HTHP = high temperature - high pressure) or produced using a chemical vapor deposition process (CVD = chemical vapor deposition). The artificially produced diamonds have no nitrogen atoms or aggregates. The testing devices for laboratory-grown diamonds make use of this distinguishing feature by detecting the presence of a nitrogen atom/aggregate in the naturally grown diamonds via UV light refraction.

Procedure for testing laboratory-grown diamonds:

The technology of the testing devices for purely laboratory-grown diamonds (ARI, SDS II) is not suitable for simulants such as zirconia or cubic zirconia and in these cases returns ‘diamond’ as the result. The conventional diamond tester “Diamondmate-A” (PDMT-A)" or the “Adamas” can help here, as it can identify cubic zirconia and colourless sapphires.

1st test step:
Therefore, test the stone in question in a first test step with the “Diamondmate-A”, the “Adamas” or Multitester III to ensure that it is indeed a diamond. If the tester has identified the stone as a ‘diamond’, it means that the stone is either a natural diamond, a lab-grown diamond or a moissanite.

2nd test step:
In a second test step using a tester for lab-grown diamonds (ARI, SDS II), you can then subdivide the natural diamonds from the lab-grown diamonds and moissanites.
