Many of these pieces were generously donated by supporters of the museum, making each one a small piece of the museum's legacy. Sourced from storied mining regions across the globe, these specimens were chosen for their rarity, character, and visual impact — true one-of-a-kind display pieces.\u003c\/p\u003e","products":[{"product_id":"stilbite-heulandite-on-matrix-unst-shetland-islands-scotland","title":"Stilbite \u0026 Heulandite on Matrix — Unst, Shetland Islands, Scotland","description":"\u003cp\u003eA sculptural cabinet piece featuring pearlescent stilbite fans and curved heulandite crystals rising from a textured zeolite matrix. The stilbite displays characteristic bow-tie aggregates with a silky, layered luster, while the heulandite shows the coffin-shaped terminations and soft green tint typical of fine Scottish material. Matrix surfaces are accented by golden-brown iron oxide inclusions that add depth and contrast.\u003c\/p\u003e\u003cp\u003eUnder shortwave UV (365 nm), this specimen exhibits a vivid blue-white fluorescence across both zeolite phases — with the heulandite showing a distinct cool-blue response and the stilbite a softer diffuse glow. Under 394 nm UV, the piece transitions to a warm violet-purple bloom, particularly intense across the heulandite zones.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eLocality:\u003c\/strong\u003e Unst, Shetland Islands, Scotland\u003cbr\u003e\u003cstrong\u003eMinerals:\u003c\/strong\u003e Stilbite-Ca, Heulandite\u003cbr\u003e\u003cstrong\u003eClass:\u003c\/strong\u003e Zeolite Group\u003cbr\u003e\u003cstrong\u003eUV Response:\u003c\/strong\u003e Blue-white (365 nm) · Violet (394 nm)\u003c\/p\u003e","brand":"Terra Specimens ","offers":[{"title":"Default Title","offer_id":49340080685307,"sku":null,"price":110.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0828\/0034\/5339\/files\/7E830A4E-72B7-4844-BE0F-A568EA5254BB_d76f0052-9c25-4103-a549-3d835316255f.png?v=1789897023"}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0828\/0034\/5339\/collections\/18867549-F466-41A0-947D-83F637A49AB6.png?v=1789893651","url":"https:\/\/terraspecimens.com\/collections\/museum-treasures-collection-1.oembed","provider":"Terra Specimens ","version":"1.0","type":"link"}
