A remarkable quartz crystal with dumortierite inclusions from Brazil. The crystal is developed as a complete doubly terminated floater, showing well-formed terminations on both ends and an attractive translucent appearance. Quartz specimens containing dumortierite are highly sought after, and this example stands out for its crystal quality, aesthetic form, and the distinctive blue inclusions visible within the quartz. A fine representative of this rare and desirable combination.

Damaged specimen will be refunded when I get a photo directly the same day the specimen was delivered. Then we can discuss if the broken specimen needs to e returned to the sender and if still represents a value or if it is a complete loss. Lost parcels need an investigation process from the Post service, which can take up to 4 weeks, as soon the Post service confirms that a parcel is lost we will send full refund.
I accept returns when you are not satisfied. The return / the message that you are not satisfied needs to come in during one week. I also accept exchanges at a simila value under the condition that the invoice for the specimen to exchange was already paid.
