Set of 3 Sea Urchin Tests – Three Different Species A varied set of three sea urchin tests, each representing a distinct species with its own texture, structure, and natural coloration. The group offers an interesting contrast between darker, more robust forms and lighter, finely detailed specimens. 1) Stomopneustes variolaris Weight: 85 g Dimensions: 10.7 × 10.7 × 6 cm A solid and well-preserved specimen with a dark test marked by lighter tubercles and subtle greenish tones. The pronounced structure and strong profile give it a bold appearance. 2) Echinothrix calamaris Weight: 10 g Dimensions: 6.5 × 6.5 × 3 cm Lighter and more delicate, this specimen shows a refined surface pattern with soft pale and lilac tones. The symmetrical layout of the tubercles creates an elegant geometric effect. 3) Phyllacanthus imperialis Weight: 50 g Dimensions: 7.6 × 7.5 × 5.3 cm Compact and well-balanced, featuring clearly defined tubercles and a harmonious rounded form. The natural coloration enhances its decorative appeal. All three tests are naturally cleaned and retain their fine structural details. A balanced and visually interesting set, suitable for collectors, educational use, or refined marine-themed display.
