Very fun advent calendar
Brilliant advent calendar. Unique, fun, and good size crystals each day. Contains a wide variety with no repeats. The extra accessories it comes with (e.g., the bag, necklace etc) are good quality and fun. Great for kids and adults. Extra info on each crystal daily would be interesting; possibly a QR code to a page with more detail. Would recommend for definite as it was great value.

Great calendar for kids who love gems
Was a really good calendar. Kids really enjoyed opening it and finding gems each day. There was a little disappointment that they didn't get all the ones shown and had a couple of doubles. The dig out on the 24th looked great but our gem was just under the surface at the very top of it so was out after about 4 scrapes and we were just left with the rest of it Would still buy again. Was still worth the money and was still enjoyed

Top class customer service
After a slight disappointment with one stone missing, we got in touch with think blue marble, and they have gone above and beyond to correct the problem. A replacement calendar was dispatched as soon as they received our email. Fantastic customer service. Thank you
