Blue Sapphire: 1mm Round Cut Lab Stones for Fine Jewelry

When building fine jewelry, the smallest stones often demand the highest level of consistency. These 1 mm lab-grown blue sapphires are offered as a precision jewelry supply for bench jewelers, setters, and makers working in micro-scale applications where tolerance control matters.

These stones are intended for ultra-fine accent and detail work, including pavé, micro-pavé, bead-set bands, edge detailing, and dense pattern layouts. Each sapphire is cut to uniform diameter with consistent pavilion depth and clean facet junctions, allowing predictable setting behavior across repeat pieces and production runs.

The blue color is even and controlled, providing visual continuity when setting multiple stones side-by-side. This size range is especially suited for designs where color presence must be subtle but precise rather than dominant.

This listing is for loose stones only. No settings or finished jewelry are included.
