Improve the atmosphere in your home. Feel the health benefits with these beautiful natural crystals and geology specimens. Many of these items are deemed as "museum" quality. There is also a huge handful of natural uncut ruby, some of which display natural crystalline form which is very rare to find. One sample of amethyst from Uruguay is of the rarest, and most beautiful dark violet colour. This collection would be suitable for university / school as well as private collectors. Send PM for more details. This collection has been built by me over the last 30 years from all around the world including south America, Europe, Africa, and I am so sorry to see it to have to go, but have to leave Doha and it's too big to ship with me to my small home
