Diamond quality: 4 Cs

For our jewelry, we use only synthetic diamonds that meet high quality standards. These are grown in a laboratory. You can read exactly how this works in our article on Lab-Grown Diamonds. Even though our synthetic diamonds do not grow naturally, they are just as pure and beautiful as their natural counterparts. They are chemically and visually identical to the stones that form deep within the earth over millions of years. The only difference is that they are grown much faster and, according to our sustainability report, have a lower CO₂ footprint than conventionally mined diamonds. Read more about the differences in CO₂ emissions and production conditions in our current sustainability report and in our We mind initiative.

Very few people know that a carat describes the weight of the diamond. A diamond carat is 0.20 grams. Depending on the cut of the diamond, a carat can vary in size, but the look can often be deceiving: If a stone has a large cut and is cut less deeply, it may appear more valuable than it actually is. The carat weight does not indicate the size of the stone..

Color, i.e. the diamond color, shows what color a white diamond has, for example whether it is colorless or has a tint. The best diamond quality is colorless or a very fine white and therefore the most valuable. Color is one of the most important factors in determining quality and ranges from D = colorless to Z = clear tint. The white, synthetic diamonds from Maren Jewelery always have the color DG = colorless to almost colorless..

The cut of the diamond is one of the most important criteria for determining the quality and value of a diamond. This is also the reason why the cut has become more and more important in recent years. However, the cut has nothing to do with the shape of the cut, whether a stone is cut round or square. Rather, it is the quality of the cut, how the facets of the cut stone interact and shine with the light. The better a stone is cut, the better the light can break and the stone can sparkle..

The diamond clarity or clarity describes the degree of purity of a diamond. Diamonds are carbon compounds. Normally, these develop over millions of years under high pressure. Other minerals can also get lost in the stone, these are categorized into three levels: IF=flawless, VS=very small inclusions and SI=small inclusions. The visibility of the inclusions and thus the diamond quality is always evaluated under 10x magnification

You shouldn’t consider anything else when choosing a stone for your engagement ring. After all, the diamond is a symbol of your love and should be correspondingly beautiful. That is why we always use the following diamond quality for our lab-grown diamonds: the color of our stones ranges from D-G, meaning colorless to near-colorless. The clarity is vvs-vs, which means: almost no inclusions, and the cut grade is "very good" to “Excellent.” Overall, this very high quality of the lab diamonds used is, in our opinion, the most suitable combination for jewelry pieces. An even higher quality becomes more expensive, but to the naked eye it is not noticeably better—that is, more sparkling, whiter, or more flawless.

An engagement is a deeply emotional and personal moment of love, which the engagement ring symbolically preserves for eternity. If you want a ring with gemstones for the engagement, then in addition to diamond quality, it is essential to assess whether the diamonds in the engagement ring are certified and traceable in origin or were artificially grown in a laboratory. From a size of 0.5 carats, the diamond should come with an official quality certificate, as is also the case with the synthetic diamonds at Maren Jewellery. In addition, diamond quality should be evaluated based on the 4 Cs in order to determine the quality of the stones and therefore also of the entire piece of jewelry.
