Interesting Facts about Diamonds

Ring Sizes

To determine your ring size, take a ring that fits you well and use a ruler to measure the inner diameter, ie from one inner edge of the ring to the opposite inner edge.

 

Example: A ring with an inner diameter of 15mm has ring size 47.

Diamond Buying Guide

The quality of a diamond is described internationally with the so-called 4 Cs: carat (weight), color (color), clarity (purity) and cut (cut).

When buying diamonds, however, other properties are essential:

certificate

A certificate is absolutely essential for your security. The scientific testing laboratories enjoy international recognition for their certificates: GIA, HRD, IGI.  

Competence and Confidence = competence and trust.

It is fundamentally necessary for an evaluation to be carried out by renowned and neutral institutes such as HRD, IGI and GIA. As a diamond dealer with 30 years of experience and excellent contacts to the most important diamond trading centers in the world, we offer you the best quality at the best prices.

 

Diamonds offer their owner a maximum of international mobility, value concentration and discretion. As an investment, however, the long-term character should always be emphasized. The standard sizes are best for beginners, i.e. quarter, third, half and one carat.

One-carats must weigh at least 1.00 carats, half-carats 0.50 carats, because diamonds are valued according to weight categories. For example, 0.99 carat costs about 30 percent less than 1.00 carat!

If in doubt, always choose the better quality, rare stones are naturally always in demand. Classics are flawless white stones in the colors D (River) to H (Wesselton) in brilliant cut.

The finish - the cut - should be rated at least "very good" to "good". In addition to the cut - one of the 4 Cs - there are three other main criteria: Carat, Color, Clarity.

Take a close look at the provider. Dealers with many years of market experience have proven their trustworthiness and competence with countless satisfied customers.

In general, a price comparison from different providers makes sense, whereby of course only stones with the same strict origin (the three globally recognized certifying institutes GIA, HRD, IGI) should be used.

Highly interesting and usually breathtakingly beautiful are diamonds in intensive natural colors, the "fancy colors". This special area is reserved for lovers of colored stones, without individual guidance every purchase is a loss!

What do the Purities mean?

The basis is the view through the 10x magnifying glass:  

At 10x magnification no inclusions are visible, the stone is

IF = internally flawless or LC = flawless  

If inclusions are only (very) difficult to detect, the purity is referred to as

VVS = very very small inclusions or

VS = very small inclusions

 

If inclusions are visible at 10x magnification, they are called

SI = small inclusions

 

Recognizable inclusions begin with the designation

P1 = and end at P3 (P stands for Piquè)

Which Diamonds are suitable for Tooth Jewellery?

No smile can be more brilliant!

 

If you are looking for something special, then real dental diamonds are an elegant and exclusive piece of jewellery. They make every smile shine!

Up to a size of 0.07 carat, diamonds can be used as tooth jewelry by a dentist who specializes in them. In contrast to crystal glass stones or zirconia, the sparkle of these gemstones is unsurpassed and the color of the diamonds should be at least Top Wesselton.

Are the Diamonds conflict free?

Our diamonds are conflict free. We adhere to and support the Kimberley Agreement of 2002 to stop the trade in conflict diamonds used to fund wars. Learn more here: https://www.kimberleyprocess.com/en

What is the most popular Diamond Cut?

The brilliant cut is the most popular cut for stud earrings, pendants and rings.

Developed in 1981  After the brilliant cut, the princess cut is the most popular shape of a diamond, especially for engagement rings. It is square, but can also be minimally rectangular. Because of their shape, princess-cut diamonds can be placed next to each other without a gap and are therefore particularly suitable for eternity rings or tennis bracelets. 

Fancy Color Diamonds

Diamonds are found in all colors of the rainbow. The intensity of the color is decisive for its rarity. In contrast to white diamonds, the clarity is almost irrelevant. For example, a Fancy Intense Pink

or Blue have inclusions visible to the eye and still cost a hundred thousand dollars or more per carat.

No white diamond with visible inclusions will ever reach these levels. A white diamond with visible flaws can only be sold at a significant price reduction, the same quality in purple, for example, would cost a fortune.

The origin of "fancy colored" diamonds is extremely rare and has not yet been fully explored. That, too, makes them something very special.

Only a few thousand carats of intensely colored diamonds are found each year compared to millions of carats of white diamonds. And most of these are only cut in small stones weighing well under a carat.

Fancy colored diamond prices have never fallen since price records.

The pink diamonds from the Argyle Mine in Australia are among the rarest gemstones in the world. Every year, a few selected stones of this color are sent on a sales tour around the world. The Argyle mine has been closed since November 2020 and the prices for these pink diamonds have exploded.

So it's all about the color. The more color the better, the most colorful stones are also the most beautiful, but at the same time the rarest and most expensive. Christies and Sothebys have held auctions dedicated to fancy diamonds for many years. Here the most beautiful of the rare stones regularly achieve record prices. No stone is comparable to a second. The Hope Diamond is perhaps the most well-known colored diamond and its scientific grade is Fancy Deep Blue.

The definition or graduation of the color saturation is done in nine different categories, whereby the addition fancy (freely translated: special, extraordinary) is already a degree of color presence:

pale
very light
light
fancy light
fancy
fancy dark (fancy dark)
fancy intense (fancy intense)
fancy deep (fancy deep)
fancy vivid

Carat

Carat
The weight of a diamond is measured in carats. One carat consists of 100 points. Thus, the weight of a diamond of 75 points is equal to 3/4 or 0.75 carat. One carat has 0.2 grams.
Das Gewicht eines Diamanten wird in Carat gemessen. Ein Carat ist unterteilt in 100 Punkte. So entspricht das Gewicht eines Diamanten von 75 Punkten 3/4 oder 0,75 Carat. Ein Carat hat 0,2 Gramm.

Treated Diamonds

Increasing demand with a very limited supply of colored diamonds has pushed prices up. This development has also led to the fact that particularly rare colors such as pure pink, blue or pure green are now also being produced artificially.

 

The best developed method is referred to as HPHT (High Pressure High Temperature). These laboratory products are recognized as such by every gemmological institute and e.g"Treated” or"Labdiamond". 

At best, they are only worth a very small fraction of the original.

Pink Diamonds

Pink diamonds - the most coveted around the world"pink diamonds" - are an affair of the heart.

 

Such a diamond even in the smallest size available (0.01 ct.) is a love for life.

 

In addition to the classic white diamonds, rarer naturally colored diamonds are also found in some mines. These so-called fancy colors impress in the most beautiful rainbow colors, with one color particularly standing out: pink.

A pink diamond is more coveted around the world than ever before.

If its color is very intense, the best pieces today cost upwards of one million USD per carat. These prices are achieved for the very rare pink stones in every auction.

No wonder, knowing that they come from the Argyle mine in western Australia. Because of their color intensity, they are the most expensive diamonds in the world. There is currently a booster: the mine was closed in November 2020 after 37 years after the diamond deposits had been fully exploited. With the end of the Argyle mine, prices are expected to skyrocket even further.

 

Because of their uniqueness, pink diamonds have long been regarded as a safe investment.

Christies and Sothebys have regularly reported new records at their auctions for decades. For a private investor, they represent an almost ingenious combination of the most important factors for an investment. International value, small, discreet and easy to transport. Especially in times of great uncertainty, such material assets give a great feeling of security.

Pink diamonds have always been in a league of their own. Prices have not fallen once since price-tracking began, and it is not expected to do so in the future. The explanation for this is as simple as it is logical: pink diamonds are extremely rare because only a few of the hundreds of thousands of diamonds mined are pink. It is assumed that the supply of diamonds will decrease in the long term because the production volume is steadily decreasing.

 

Interested investors should seek advice from a dealer who has many years of experience with naturally colored diamonds. This is the only way to ensure that the commitment can be optimally adapted to individual needs.

We advise you personally and individually. With more than 30 years of experience in the diamond trade, you have a competent and trustworthy partner at your side.

Diamond and Brilliant - what's the Difference?
