Since 1948, KURZ has championed excellence in fine jewellery. Today, we extend that commitment to cultured diamonds. Our collection brings you stones identical to earth diamonds in every measurable way, created through advanced technology with ethical sourcing and transparent origin. For those who value exceptional quality, ethical sourcing, and forward-thinking design. We believe luxury should be both beautiful and responsible. The same passion. The same heritage. Made for tomorrow.
Atelier-Diamonds - Cultured Diamonds
Every diamond begins with a seed. In our atelier, we recreate nature’s most extraordinary process, growing diamonds through heat, pressure, and time. Not in millions of years, but in weeks. Each cultured diamond inherits the same crystalline perfection as its earth-born counterpart, carrying forward a tradition of excellence and a commitment to the future.
GROWN TO SHINE
A GLIMPSE OF INFINITY
Light captured in carbon. Fire frozen in time. A cultured diamond reflects not just brilliance, but possibility. It represents a choice: to honour heritage while embracing innovation, to celebrate beauty while respecting our planet. Each stone tells two stories at once: the ancient art of gemmology and the promise of sustainable luxury.
Cultured diamonds offer something remarkable: exceptional quality without compromise. More carats for your investment. Guaranteed origin and ethical sourcing. The same physical, chemical, and optical properties as natural diamonds. Certified by the International Gemological Institute. This is not an alternative to luxury. This is luxury, reimagined for tomorrow.
A SUSTAINABLE CHOICE
Our master craftsmen approach each cultured diamond with the same dedication they bring to earth diamonds. The same precision and passion. Because whether formed in the earth’s depths or in our laboratory, a diamond’s beauty depends entirely on the skill of the cutter, the quality of the stone, and the artistry of the setting.
Creating beauty need not come at the earth’s expense. Our cultured diamonds require no mining, no disruption of natural habitats, no uncertainty about origin. They represent the convergence of Swiss precision, modern technology, and environmental responsibility. Grown using renewable energy sources, each cultured diamond reduces environmental impact while delivering the same brilliance you expect from KURZ. A diamond that shines as brightly for the planet as it does on your hand.
Cultured diamonds are grown using the same forces that create natural diamonds: carbon, heat, and pressure. Through Chemical Vapor Deposition (CVD), we replicate the earth’s process in weeks rather than millennia. The result? A diamond with the same hardness, the same refractive index, the same fire and brilliance. Even trained gemmologists have difficulty distinguishing between cultured and natural diamonds without examining the certificate.. Every KURZ Atelier Diamond undergoes the identical evaluation process as our earth diamonds. The same master gemmologists. The same rigorous assessment of the 4 C’s: Carat, Colour, Clarity, and Cut. Each stone of 1.00 carat and above receives individual certification from the world’s leading authority in diamond grading IGI.
SAME EXPERTISE SAME STANDARDS
EXCEPTIONAL QUALITY ACCESSIBLE LUXURY
KURZ Atelier Diamonds range from 0.75 to 2.50 carats per stone, featuring the finest colour grades (D-E-F: exceptional to rare white) and superior clarity (VVS to VS: inclusions invisible to the naked eye). Our commitment to exceptional cut quality ensures maximum brilliance and fire. What makes cultured diamonds truly remarkable? They offer significantly more carats for your investment while maintaining the same beauty and durability as earth diamonds. This means exceptional quality in larger sizes, at accessible prices, without compromise on colour, clarity, or cut.
