Radiolarians

Diatom Lab offers both arranged and strewn Radiolarians for sale. Only the best, cleanest, unbroken specimens are hand selected, and all slides are quality checked on our in-house Zeiss Axio Imager.A2 research microscope before shipment. Diatom Lab offers perfectly cleaned, selected Radiolarians that are micromanipulated paying attention to their ideal positioning to show off the best features. All current and fossil Radiolarians are cleaned in our laboratory using innovative, and professional techniques.

We use the proprietary PRIME MOUNTANT high refractive index microfiltered mountant with a refractive index of over 1.7 and excellent chemical stability!


Dowload the latest article that Stefano Barone has written about Radiolarians, with the introduction to his unusual psychological perspective (more works will be written in the future):




The German naturalist, artist and philosopher Ernst Haeckel (1834-1919) with the publication of his most important work, "Kunstformen der Natur" series (in English: "Art Forms in Nature") beginning in 1899, brought the intrinsic beauty of microscopic Radiolarians to the public through his scrupulous and exquisite watercolors.  "Kunstformen der Natur" had a great impact on twentieth-century art and architecture and Haeckel's Radiolarians helped to show that art and science can be friends.
Radiolarians are a component of the sea zooplankton and a quote from the old book "Nature trough microscope and camera" by Richard Kerr (1909) is useful to describe their immense beauty: “When a number of these fossil forms are placed under the microscope, they will be found to be a thing of beauty and a joy for ever. It is no exaggeration to say that sermons have been preached which have been prompted or suggested by a microscopic view of these matchless and exquisitely beautiful organisms part of Nature’s building material. And why not ? Nature is the ‘ other book,’ and the more both books are thoroughly understood, the more they will be found to harmonise. I recommend the polycystina to all grades of thinkers, to scholars of every school of research, to divines, to philosophers, to teachers of youth, to leaders of thought, with the full confidence that the study of these almost invisible relics of life will impress their minds with the grandeur of Nature, the marvels of geology, the possibilities and the potentialities of mere specks of flint. And their influence is not likely to end even there".
