Rio Grande To Offer Calibrated Diamond Melee

Rio Grande’s new Calibrated Melee Diamond Program lets customers filter by exact specifications.

Albuquerque, N.M.—Rio Grande has launched a program allowing customers to search and purchase calibrated diamond melee on its website.

Through its new Calibrated Melee Diamond Program, customers can search and purchase calibrated melee and matched pairs of natural and lab-grown diamonds.

Customers can filter by exact specifications such as size, carat weight, and shape, ensuring consistency for both CAD-driven workflows and traditional bench fabrication, the supplier said.

Along with calibrated round melee, the comprehensive selection includes an array of fancy shapes such as oval, pear, emerald, marquise, and princess for greater design flexibility.

The offering fills a gap in the market, as calibrated fancy shapes are more difficult to source, due to cutting complexity and inconsistent size assortments, according to Rio Grande.

“Calibrating small stones by size and shape has historically been a challenge for jewelers, especially when it comes to fancy shapes, which most suppliers simply do not carry in consistent, ready-to-use assortments,” said Arien Gessner, president of Rio Grande.

“Our new calibrated melee diamond offering, including one of the industry’s most robust selections of calibrated fancy-shape melee, means customers can finally source precisely matched stones with confidence. It saves time, reduces waste, and supports our customers in delivering designs that meet the highest standards of craftsmanship.”

Rio Grande said the precision-cut melee diamonds are ideal for engagement rings, fine jewelry, high-volume production, and intricate layouts where accuracy is essential.

The new offering reflects the growing demand for fancy shapes, as well as flexible sourcing for both natural and lab-grown diamonds, according to the company.
