Grandior Studio provides white-label sourcing, jewelry manufacturing, and fulfillment for brands looking to launch or expand without holding inventory or setting minimum order quantities. Its services cover the process from product selection to delivery: clients can choose from ready-made collections or commission custom designs, then order pieces as customers buy them. The studio sources certified lab-grown and natural diamonds, moissanite, precious stones, and semi-precious stones, with options across cuts, grades, and carat weights.

Jewelry is made to specification in gold, sterling silver, platinum, and other available finishes, with quality checks against approved samples. Custom designs receive CAD modeling, renders, and a physical sample, and remain exclusive to the commissioning brand; ready-collection designs are shared across the partner network. Grandior also offers branded, tracked direct-to-customer shipping, store setup or catalog integration for Shopify and WooCommerce, order management, customer support, and product and lifestyle imagery.

It states that orders can be dispatched within seven days and ships to more than 20 countries
