Reliable access to calibrated small stones is critical for controlled jewelry builds.

These round-cut lab-grown alexandrite stones are available in six calibrated diameters from 1 mm through 2.5 mm for bench jewelers and makers who require consistent sizing, predictable material behavior, and fast domestic availability without the variability or sourcing delays common with natural melee.

The smaller 1–1.75 mm sizes present subtle lavender-to-green tones under shifting light, making them well suited to pavé, halo accents, fine inlay borders, and detail work where uniformity and fitment matter.

The 2–2.5 mm sizes offer greater light return and shift more noticeably under mixed lighting, making them useful as side stones, cluster elements, larger halo accents, and deliberate precision-inlay features.

Choose your stone size and available purchase quantity from the variation menus.

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