Synthetic Diamond Jewelry Expert on the Production of Lab-Grown Diamonds

>To be honest, lab-grown diamonds can only be considered truly sustainable if they are produced using renewable energy. [...] Fenix Diamonds has made significant investments in Gujarat, India - the diamond capital of the world - in generating its own renewable energy through solar and wind turbines. About 70% of our energy needs are generated from our own sources. The remaining 30% is green energy that we obtain through the government's "Green Tariff" system. This is green energy that does not come from our own renewable sources, but from other renewable sources, and is provided by the government.<

Synthetic Diamonds vs. Natural Diamonds

Synthetic diamonds, also known as lab-grown diamonds, are produced in the laboratory under controlled conditions. They have exactly the same chemical composition and identical structural properties as natural diamonds. With strict quality controls and careful cutting processes, they are in no way inferior to their natural counterparts in terms of brilliance and quality, and can compete with them on equal footing and be evaluated using the 4 C’s. The only difference: they are not formed in the Earth’s crust, but in the laboratory. Even major luxury brands such as LVMH, FRED, and Prada rely on synthetic diamonds. We are delighted that lab-grown diamonds are playing an ever greater role in the jewelry industry and offer another option for high-quality diamond jewelry.

Evaluate your diamond jewelry: the 4 C’s

The quality of your diamond jewelry depends on the quality of the precious metal used, as well as the quality of the diamonds employed. When evaluating the quality of a diamond, four factors play a role: the weight (Carat), the color (Color), the cut quality (Cut), and the clarity (Clarity). Together, these evaluation factors are called the 4 C’s, by which every diamond can be classified. In a journal article, we explain the four C’s and their exact evaluation criteria in more detail. At Maren, we always use the following diamond quality for our lab-grown diamonds: The color of our stones ranges from D-G, meaning colorless to nearly colorless. The clarity is vvs-vs, which means: almost no inclusions, and the cut quality is "very good" to "Excellent." This overall very high quality of the lab diamonds used is, in our opinion, the best-suited combination for jewelry pieces. A higher quality would be more expensive but cannot be recognized with the naked eye as better, i.e., more sparkling, whiter, or flawless.

Which diamond jewelry suits you?

Only through the diamond cut does the rough diamond become the sparkling and radiant gemstone that we admire in our jewelry pieces. When choosing the perfect diamond jewelry, the craftsmanship and art of the cut are crucial to evaluate the differences and make an informed decision. There are many types of diamond cuts, each giving a unique personality to every piece of jewelry. Only you can decide whether you prefer, for example, a brilliant cut, princess cut, pear cut, emerald cut, or another cut. It largely depends on your style and preferences. We have compiled the special features of the cuts for you in a journal. If you need further assistance with your selection, you can always schedule a personal consultation with our jewelry designer Helge Maren to discuss your preferences and wishes. The perfect diamond jewelry for you is surely within reach!

Häufige Fragen zum Diamantschmuck

Is diamond jewelry a good gift for special occasions?

Diamond jewelry is definitely a very special and valuable gift. Due to its symbolic nature, diamond jewelry has the ability to preserve memories, wishes, or feelings and keep them accessible for a lifetime when worn. Especially on special occasions, it is therefore a very personal and emotional gift that – if chosen carefully and thoughtfully – will accompany the recipient for life. This effect is further enhanced by an individual engraving.

How do I find the right size and best setting for diamonds?

It is difficult to make general statements in this regard, as the optimal size of a diamond depends on individual preferences, the size of the jewelry piece and the hand, the budget, and last but not least, the frequency of wear. So try to consider what type of jewelry the gemstone will be set in, how often you wear this piece and where, how eye-catching the stone should be, and what budget you have available. The optimal setting also depends, besides aesthetic criteria, on the choice of diamond, the required protection, and the desired everyday suitability.

How valuable is Maren Jewellery's diamond jewelry and is it a worthwhile investment?

At Maren Jewellery, we use lab-grown diamonds of very high quality, set in 18-carat recycled gold jewelry. Our diamond jewelry is suitable not only for its emotional value but also as a small financial investment, since the gold used can be completely melted down again. Investing in diamonds, however, is a rather demanding matter that requires a lot of expertise. The value of a diamond is determined not only by its weight but also by its cut, color, and clarity. Since these are not always easy to determine, even experts often disagree. While a certain material value of the diamond will always remain and a total loss is very unlikely, you do not receive returns or interest like with other investments. Our jewelry is therefore certainly valuable, and especially the gold retains its value, but for investment purposes, rather rare pieces with collector’s value are considered.

Can I safely buy diamond jewelry online?

Yes! The jewelry is shipped to you insured, and you can try it on comfortably at home. If you are still not convinced, you can return the ordered diamond jewelry to us within 2 weeks. Of course, we also insure the return shipment, so nothing can go wrong with the order and you can shop online without worries.

What services do you offer related to diamond jewelry?

We offer you various services to ensure you are forever happy and satisfied with your diamond jewelry. This includes jewelry engraving, which allows you to personalize your piece even more, jewelry cleaning so your diamonds shine forever like on the first day. In addition, we offer jewelry remodeling, which lets you change your piece if you no longer like it or it no longer fits.
