In the U.S., lab-grown diamond sales jumped 16% in 2023 from 2022, according to Edahn Golan, an industry analyst. Social media posts show millennials and Generation Zs proudly explaining the purchase of their lab-grown diamonds for sustainability and ethical reasons. Natural diamonds take billions of years to form and are difficult to find, making their price more stable. Globally, lab-grown diamonds are now 5-6% of the market and the traditional industry is not taking it sitting down. It's also still true in more rural areas of the United States, while lab-grown diamonds have taken off more in the cities.

Zircons Are Not the Gem You Probably Think They Are

If you could ask the humble zircon, the answer might be mistaken identity and decades of undeserved obscurity. In the Victorian era, the peak of popularity for zircons, a mined mineral, colorless ones were regularly used as diamond alternatives and blue ones were particularly popular. “Zircon can come in a wide range of colors — blue, yellow, brown, green and, rarely, a purplish-pink color,” said Nathan Renfro, senior manager of colored stone identification at the Gemological Institute of America. Then, along came cubic zirconia, an inexpensive synthetic crystal discovered in the 1930s but not developed to the point it could be faceted until 1969. By the end of the 1970s, it bypassed zircon and became the most common diamond simulant.

But as of the start of January, EU and G7 countries have banned the direct purchase of non-industrial diamonds from Russia. This move will be followed by further restrictions on the import of Russian diamonds processed in third countries starting in March. Industry groups including the World Diamond Council, Antwerp World Diamond Centre, the Gem and Jewellery Export Council of India and the Gemological Institute of America (GIA) have been working together to develop an effective solution. What does this mean for the diamond industry? LVMH-owned Tiffany and Richemont both said they stopped sourcing Russian stones shortly after the war in Ukraine broke out.

How would you feel about giving, or receiving, a 4-carat engagement ring? Lab-diamond producers are putting them within reach, and (almost) nobody can tell they cost less than a Ferrari. Those rings are also funding an even bigger aspiration: putting diamonds into electronics. Walk into a jeweler these days and chances are you will be offered a lab-diamond option. It is an enticing one: Lab-grown diamonds have essentially the same chemical, optical and physical properties as mined diamonds, according to the Gemological Institute of America.
Automic Gold's growing popularity is backed by an unconventional strategy: ditching those major platforms and selling only on its own website. Al Sandimirova officially founded Automic Gold, an size- and LGBTQ-inclusive jewelry company in 2016. In 2021, its first full year exclusively selling jewelry from its online storefront, it brought in $4.8 million. "Regular companies assume it's harder to target the LGBT community," Sandimirova says. Searching for outletsSandimirova named Automic Gold — spelled to include "AU," the chemical abbreviation for gold, and pronounced like "atomic" — with "autonomy," independence and freedom in mind.

"It is extremely rare and to have a collection of eight it is super exciting," said jewellery specialist at Sotheby's Geneva, Marie-Cécile Cisamolo.
