Reliable access to micro-scale accent stones is critical for precision jewelry work. These 1 mm lab-grown alexandrite stones are offered specifically for bench jewelers and makers who need consistent sizing, predictable material behavior, and fast domestic availability without the variability or lead times associated with natural micro stones.

Lab-grown alexandrite is a chromium-bearing gemstone with a stable crystal structure and controlled optical behavior. At this scale, the stones present subtle lavender-to-gray tones under neutral studio lighting rather than dramatic color shift, making them suitable for pavé, halo accents, fine inlay borders, and detail work where uniformity matters more than visual dominance.

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