This is a great specimen with numerous intergrown, sparkling botryoids of intense green primary Malachite, richly perched on contrasting ocher-coloured Quarzite matrix. The superbly clustered Malachite spheres are very well composed and making a well balanced display piece. Such specimens came out at the Star of Congo Mine a few decades ago and dispersed on the market. Super in colour and integrity. Highly aesthetic material, hard to obtain nowaydays.
