Nivoda Upgrades Gemstone Marketplace

Gemstone sourcing platform Nivoda has announced a revamp of its B2B marketplace, debuting in conjunction with this week’s AGTA GemFair Tucson, where Nivoda is exhibiting and showcasing the upgraded site (now live).

“With this platform revamp, we’re delivering faster navigation, smarter sourcing tools, and a consistently high quality selection that customers can rely on,” said Pia Tonna, category lead for gemstones at Nivoda, in a statement.

Nivoda gives jewelers and retailers real-time, on-demand access to over 40 different gemstone varieties and subtypes from a curated network of partners.

In addition to its site relaunch, Nivoda is readying Gem Club, an exclusive membership program offering webinars, industry insights, gemstone education, and a concierge sourcing service. The program will be introduced in the U.S. first and expand globally “shortly after,” according to the company.

“With Gem Club, we’re creating a space where knowledge and community meet—a hub for education, sourcing support, and industry insight designed to help our clients grow their business with confidence,” Tonna said.

Nivoda also announced a new agreement with GemWorld International’s GemGuide, the independent authority on market-driven wholesale pricing and gemstone reporting, that will give customers access to benchmark pricing and up-to-date gemstone intelligence.

“Since joining Nivoda in May 2025, our mission has been clear: to elevate the gemstone-buying experience for our clients,” said Tonna. “What’s been most exciting is seeing established diamond buyers confidently expand into color, alongside new retailers entering the gemstone category for the very first time.”
