It is said that Blue Apatite can promote motivation and independence. Apatite can be very brittle and have a hardness of 5 on the MOHS scale. For these reasons they should be used in perhaps a pendant or earrings, as a ring is more likely to get knocked and damaged. Their beautiful color is quite irresistable and could be just what your next piece of jewelry needs. This parcel of Merelani material has been hand selected for quality and color with pieces weighing from approximately 1.5 – 2.8 cts in shades of beautiful teal blues for a total weight of 8.29 cts. and 4 pieces.
