Three natural blue apatite rounds from Brazil in a vivid neon aqua-teal color. These 4mm rounds are well-cut with good light return and a bright, consistent color that reads clearly even at this small scale. The transparency is good, and the characteristic fine needle inclusions of Brazilian apatite are present in each stone, contributing a gentle inner shimmer. At just under 0.80ct total for the trio, these are an efficient and visually impactful set of small rounds.
Completely untreated and originating from Brazil, these natural blue apatite rounds are ready for setting. At 4mm they sit right in the sweet spot for earring stones and accent gems, and the three-piece format means you get a matching pair plus a spare.
Natural blue apatite, set of 3 rounds, sold loose.

About apatite
Apatite is a calcium phosphate. At 5 on the Mohs scale it is soft for a gemstone and sensitive to acids, heat and knocks, so it is best for pendants, earrings or a collection.
Cleaning
Warm water, a drop of mild dish soap and a soft toothbrush are all you need. Brush behind the stone too, where dust and skin oils collect, then rinse and dry with a soft cloth. Skip ultrasonic and steam cleaners: vibration and sudden temperature changes can crack it. Keep it away from acids, including lemon juice and vinegar, and household cleaners.
Wear and storage
With a hardness below 7 it can be scratched even by quartz, which is found in household dust, and a knock can chip it. Wipe it gently and store it on its own in a soft pouch. It suits pendants and earrings better than an everyday ring.
For your jeweler
These stones are untreated. Apatite should be kept away from the torch flame, acid pickle and the ultrasonic bath. A bezel or another protective setting suits it best.
