Tolkowsky Diamond Rings

- The Name That Changed Diamonds Forever

Diamond Rings were changed forever by Marcel Tolkowski. A Belgian master whose perfection of the Diamond cutting art has established one of the worlds highest quality brands for Diamond Rings and Earrings. Tolkowsky are world leaders for clarity and brilliance in their Diamond Rings and Earrings. We think this is due to their understanding that perfect Diamonds, are hand crafted by masters.

Tolkowsky Diamond Rings feature stones that measure exquisitely for the characteristics Carat, Clarity, Color and Cut. Tolkowsky’s Diamond Rings set the standard for these “Four C’s”. All Diamond rings from Tolkowsky go through a Color, Clarity, Cut and Brilliance process.

Buying a Diamond Ring is not something you want to get wrong. You are about to purchase an object that will be a permanent symbol. Tolkowsky have a history of over 200 years of excellence in the Diamond industry, as a result the Tolkowsky Diamond Rings range is a guarantee of quality that is hard to find.

So why are Tolkowsky Diamond Rings an industry leader.

Diamond Rings from Tolkowsky have set the industry standard for such a long time because of their commitment to the “Four C’s”


As the only characteristic of a Tolkowsky diamond not influenced by nature, the cut is open to mistakes and bad practices. Cut a diamond incorrectly and the defining sparkle will be compromised. It is how the 57 or 58 facets (the tiny planes cut on the diamond's surface) are angled and sized that dictate how light reflects and exits the diamond, an effect known as its "fire". Make the cuts too deep or too shallow and the diamond will be less brilliant.
The cut will also determine the shape of the diamond ring. The most common shape is the round cut, but others include the emerald, the pear, the marquise, the princess, the oval and the heart shape. Marcel Tolkowsky was a pioneer of Diamond cut. His Tolkowsky Diamond rings still today maintain the commitment to high standards of Diamond cut.


The most valuable and rare colour for Diamond Rings is white, that is to say, colourless. Tolkowsky Jewellers grade absolutely colourless diamonds with a "D". The scale moves up to "Z" (don't ask what happened to A, B and C) and, between these two extremes, diamonds will display subtle coloured tones.


A Tolkowsky diamond is a natural substance, therefore unless a diamond is classified as internally flawless there will be tiny inclusions inside each diamond ring. These inclusions may be other minerals, liquids or even gases trapped inside the diamond as it was formed. Most of these inclusions are so tiny that they are not visible with the naked eye. Tolkowsky diamond rings have an extremely high commitment to clarity.


The weight, and thus the size, of a Tolkowsky diamond is measured by carat. The average size of most engagement-ring diamonds is somewhere between one carat and half a carat. Do not confuse carats with karats, the unit of purity for gold.
