Editor’s Note
This article highlights a significant development in sustainable luxury, as lab-grown technology now replicates one of nature’s rarest treasures—the pink diamond. It reflects a growing trend where innovation meets ethical sourcing in the jewelry industry.
The colored stone jewelry brand “BIZOUX,” which handles over 100 types of natural colored stones, has been offering a sustainable jewelry series using “lab-grown gemstones” since 2022. This time, it will launch new jewelry featuring pink diamonds, also known as “one of the world’s rarest gemstones,” realized through lab-grown technology, on Friday, April 4, 2025.
Natural pink diamonds are considered “one of the world’s rarest gemstones.” With the closure of the Argyle mine in Australia, the primary source of pink diamonds, in 2020, the rarity and value of natural pink diamonds continue to increase.
Lab-grown gemstones have recently gained attention, particularly colorless diamonds. They are cultivated using advanced science and technology without the need for new mining of limited resources, garnering support from the perspective of environmental and resource sustainability.
While their composition and structure are “exactly” the same as natural gemstones, they are grown in ideal conditions, resulting in superior gem quality in terms of transparency and purity. Additionally, their more affordable price compared to natural gemstones is another reason for their popularity.
Against this backdrop, BIZOUX has incorporated lab-grown technology into the rare pink diamond, leading to the development of new jewelry featuring gemstones with ideal color and size.
Even among lab-grown gemstones, producing pink diamonds is challenging compared to commonly available lab-grown diamonds, as color control is difficult, making it hard to achieve the ideal coloration for a gemstone. The new jewelry to be released uses lab-grown pink diamonds, meticulously selected for their color, which closely resembles that of natural gemstones.
The new jewelry consists of two pieces: the “Pink Diamond (Lab-Grown) K18/PT Ring Florezon,” a glamorous ring featuring a large center stone, and the “Pink Diamond (Lab-Grown) K18/PT Ring Emma,” an eternal classic eternity ring. Total carat weight is approximately 1.56ct.
“Florezon” is a glamorous jewelry series known for its design that surrounds a large center stone (over 1 carat) with eight side stones. This time, by using a lab-grown pink diamond of approximately 7mm (equivalent to 1.30ct) as the center stone, the piece has been elevated into jewelry that allows one to fully appreciate the charm of the rare pink diamond.
Great care was taken in selecting the stone’s color, choosing one with a soft, nuanced color close to that of natural pink diamonds. The side stones feature a total of 16 diamonds (equivalent to 0.26ct), and the three-dimensional setting is designed to maximize the stone’s color and brilliance.
Furthermore, the shank has been hand-finished with a matte texture by artisans, recreating an antique-like feel. The design is both glamorous and refined, offering a satisfying presence and elegant appearance.
“Emma” is an eternity ring, considered an eternal classic, where eleven 2mm-sized gemstones cover the finger. In the world of natural stones, where each stone has its own character, aligning eleven stones of the same size and color is extremely difficult with natural pink diamonds. This time, by using lab-grown pink diamonds, the balanced brilliance covering the finger, unique to eternity rings, has been achieved.
While the design is basic, to maximize the gemstone’s brilliance, this item is finished with meticulous attention to detail and artisan techniques, such as minimal prong settings and a substantial shank. The diamond’s characteristic brilliance and the soft pink color, which was a focus of this release, bring elegance to the wearer’s fingertips.
While lab-grown gemstones are gaining attention mainly for colorless diamonds, BIZOUX has been offering lab-grown colored stones, focusing on rare colored stones, since 2022.
The gemstones handled primarily include rare stones such as “Alexandrite” and “Padparadscha Sapphire” (among the world’s three major rare stones), and “Blue Diamond,” which is almost non-existent in nature. These stones are popular for their special colors and brilliance, but due to their high rarity value, it is difficult to produce jewelry in lots or craft them into jewelry at an accessible price point. Using lab-grown gemstones, BIZOUX has been delivering these as jewelry.
The premise behind this is that natural stones are “finite resources” created by nature. We believe that one of our missions is to engage in jewelry making that values resources and avoids strain and waste on the planet by utilizing existing technology.
