Extremely rare malachite with crystal Growth aroun

Rhis is from the late 1800s from South Africa this is such a glittery Specimen that has a very beautiful crystal cluster around the malachite I did put the diamond tester on the crystals and it did indeed go all the way up on the diamond tester but I'm still unsure as it's not the best tester and I'm not sure on the temperature part of it ,if tou are not completely satisfied with this Specimen I will issue a full refund ,now is your chance to possibly own this diamond cluster
