Niessing engagement rings

Diamonds: everlasting, like your love

Highlight your love

Why are diamonds so popular for engagement rings? One reason is the sheer beauty of this most precious stone of all. But even more important is the symbolism inherent to diamonds. A diamond stands for purity and utmost consistency—it is everlasting, like your love.

By the way: did you know that according to historical records the first man to present an engagement ring with a diamond to his lover was the Archduke Maximilian I of Habsburg? He slipped it onto the finger of his fiancée Mary of Burgundy for their engagement in the year of 1477.

Precious and pristine

“Diamond”, in the original sense of the word, means “the unbreakable”: a fascinating mineral from the depths of the earth, formed over millions of years under extremely high pressure and temperature. Each diamond is a natural product, each one of them unique.

For thousands of years, diamonds have been working their spell on us. In terms of chemistry, they are “merely” carbon, but they have very remarkable features: They are born in the depths, extremely hard, and very precious. There is no other substance that refracts the light as diamonds do. White light comes to sparkle in all colors. Each diamond has its very own fire. Nature knows no repetition.

A diamond and its sparkle

A diamond may be a natural product, but mankind can still influence it. Rough diamonds are cut into shape to bring out the sparkle. In a brilliant-cut diamond, a round outline and at least 56 facets form a perfect surface for reflection, creating magical plays of light. Among the many different types, the brilliant cut is certainly the classic diamond shape.

No diamond is like the other

Each diamond has a character of its own. And that is not only true for white diamonds. The smallest of mineral traces open up an entire cosmos of optical phenomena: From yellow to warm brownish hues, to bluish or pink—all of it is natural. Choose the color of your love!

We go for quality

What you can expect from us

Niessing diamonds are top quality. Independently of its certificate, each stone is specifically examined by our Niessing experts. Only the very best diamonds are suited for Niessing’s tension rings, because they are the only ones capable of withstanding the high degree of tension in the ring.

Your Niessing jeweler will help you select the right diamond for your piece of jewelry. The “four Cs” cut, color, clarity, and carat—as well as the fifth characteristic confidence—offer a good orientation.


Diamond is the hardest known substance, and also one of the most fascinating minerals. The name says it all: “adamas” is ancient Greek and means “the unbreakable”. A symbol for purity, clarity, and courage, it has been the most highly valued gemstone for many centuries. Diamonds are assessed according to the 4 Cs cut, color, clarity, and carat. Niessing vouches for the quality of the diamonds used.


Proportions, symmetry, and polish Niessing prefers the brilliant cut: round top view, 32 crown and upper girdle facets, a table, 24 pavilion and lower girdle facets. Due to the cut and the light refraction, this perfect gemstone sparkles in all colors of the rainbow. The quality of the cut is graded as excellent, very good, good, or fair.


The intensity of the hue. White or colorless diamonds are very rare. Diamond experts distinguish the following hues: Finest white/Jager and River (D, E), Fine white/Top Wesselton (F, G), White/Wesselton (H), Slightly tinted white/Top Crystal (I), Tinted white/Crystal (J), Faint yellow/Top cape (K), Very Light yellow/Cape (L), and Light yellow/Yellow (Y) (color grades according to GIA). Naturally colored yellow, brownish, red, green, and blue diamonds are also extremely rare.


Flawless or with inclusions? Diamonds are natural products and as such frequently have inclusions of minerals, cracks, and growth marks. Internally Flawless (IF) category diamonds have no inclusions visible under 10x magnification. In the Very, Very Slightly Inclusion (VVS) category, inclusions are difficult to see under magnification, Very Small Inclusions (VS) and Small Inclusions (SI) are noticeable under magnification, while the inclusions in P1-P3 (first to third piqué) diamonds are visible to the naked eye.


The unit of mass. One carat (ct) corresponds to 0.2 grams. The term stems from the original unit of weight, the carob seed, or kerátion, in Greek. The weight of very small diamonds can also be measured in points: 1 point = 0.01 ct.
