Josh - In Stock - Men's Wedding Band - PLATINUM

Lab-grown diamonds are real diamonds, chemically and physically identical to natural ones. At Vondel Diamonds, we exclusively use CVD (Chemical Vapor Deposition) diamonds, where a small natural diamond seed grows into a perfect diamond in a vacuum chamber under precisely controlled, optimal conditions. This accurately mimics the natural process underground, but in a fraction of the time and with a minimal ecological footprint. The result? Exceptional purity, brilliance, and full traceability from seed to piece of jewelry.

Because we eliminate all intermediaries and work directly with our exclusive producers, we save significant margins in the supply chain. Furthermore, the natural diamond sector has traditionally been dominated by a few major players (De Beers being the most prominent) who, through market concentration, have kept prices high for a long time. This dominant position doesn't exist for lab-grown diamonds: here, supply and demand truly determine the price, keeping it competitive and transparent. Moreover, the efficient cultivation process is less expensive than mining, which together leads to a price advantage of up to 90%.

At Vondel Diamonds, we work exclusively with the highest quality diamonds. Each of our diamonds is carefully selected for clarity grades VVS and VS, color D to F, and a Triple Excellent cut. Thanks to these strict quality standards, we guarantee ultimate brilliance and lifelong durability—only the very best diamonds are used in our collection.

Print the A4 template at 100% (actual size) and check the printed 10 cm ruler with a real ruler.

Cut out the ring strip or wrist strip along the indicated lines.

To find your ring size: Fold the ring band into a loop, slide it onto your finger, and tighten until it's comfortable but not tight. Read your size where the lines meet.

To determine your bracelet/bangle size: Wrap the wristband around the widest part of your wrist, tighten until it fits comfortably, and read the measurement in centimeters where the bands intersect. Add 1 cm to your measured wrist circumference for a comfortable bracelet fit.

Tip: Measure your ring at the end of the day (when your fingers are a little thicker)

Yes. We guarantee that all our diamonds are 100% conflict-free. We work only with certified producers who adhere to strict ethical and social standards.

At Vondel Diamonds, we do more than just use sustainable materials. Our CVD lab-grown diamonds are created without large-scale mining, leaving ecosystems intact. Because they are grown locally at processing and certification centers, we save transportation kilometers. Our CVD cultivation facilities run on a mix of conventional and solar power; the factories are actively working to increase their use of renewable energy to gradually reduce CO₂ emissions. For the remaining emissions from production and shipping, we offset each order through Trees for All by planting trees, thus actively contributing to CO₂ reduction.

Each piece of jewelry comes with a certificate from an independent laboratory, providing clear information about the origin, color, clarity, cut, carat weight of your diamond(s), and the weight of the gold plating. Furthermore, all diamonds over 1 carat receive an additional IGI certificate, which independently confirms their quality.
