Loose Gemstones for Jewelry Designers

Partner with Caleb B. Quashen to source rare sapphires, diamonds, tanzanite, and one-of-a-kind gemstones for client projects, custom designs, and meaningful jewelry.

A Gemstone Source for Jewelry Designers and Custom Jewelers

Jewelry designers need more than ordinary inventory. You need a gemstone source that understands client projects, custom design, timing, quality, and trust.

Caleb B. Quashen International partners with jewelry designers, custom jewelers, and industry clients who are sourcing loose gemstones for engagement rings, custom rings, pendants, heirloom pieces, and one-of-a-kind jewelry. Our goal is to build long-lasting relationships with designers by becoming a reliable gemstone source for stones with color, character, clear specifications, and story.

Whether you are purchasing directly, sourcing for a client, or sending a client to us to choose a center stone, we want to support the design process and help you create pieces that feel personal, intentional, and memorable.
