It is in the light passing through it.\u003c\/em\u003e\u003c\/p\u003e\u003cp\u003eDichroic glass was originally developed for NASA aerospace optical applications: ultra-thin layers of metallic oxides deposited onto glass in a vacuum chamber, each layer a fraction of a wavelength thick, producing interference colours that shift as the angle of light changes. The word dichroic means two colours, but in practice a well-made dichroic glass cabochon contains the entire spectrum. From one angle this stone is a deep amber-rust with swirling brown undertones. From another it erupts into electric blue, teal, and prismatic rainbow flashes scattered across the surface like a fireworks display suspended in glass. It will not look the same in two different rooms. It will not look the same twice in the same room.\u003c\/p\u003e\u003cp\u003eThe cabochon is a circular dome, the surface a perfectly smooth convex curve, set within a plain circular disc bezel in sterling silver. The pendant form is modernist and architectural: a flat silver disc with a raised bezel ring at the centre, no engraving, no additional decoration, the geometry of the setting allowing the stone to occupy the entire visual field. The construction is solid and well-made, the bezel holding the cabochon cleanly and securely.\u003c\/p\u003e\u003cp\u003eThe chain is a heavy rope chain, the helical twist of the construction clearly visible, with a spring ring clasp stamped with a purity mark in a small rectangular cartouche. The pendant bail is also stamped 925.\u003c\/p\u003e\u003cp\u003e\u003cspan style=\"text-decoration: underline;\"\u003e\u003cem\u003eThe Particulars:\u003c\/em\u003e\u003c\/span\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eType: Pendant necklace\u003c\/li\u003e\n\u003cli\u003eStone: Dichroic glass cabochon, circular dome, amber-rust base with electric blue, teal, and rainbow iridescent flashes\u003c\/li\u003e\n\u003cli\u003eSetting: Plain circular disc bezel, sterling silver, modernist form\u003c\/li\u003e\n\u003cli\u003eMetal: Sterling silver, stamped 925 on bail\u003c\/li\u003e\n\u003cli\u003eChain: Heavy rope chain with spring ring clasp, stamped 925 on clasp cartouche\u003c\/li\u003e\n\u003cli\u003eNote: Colour shift is dramatic under different light conditions, as photographed\u003c\/li\u003e\n\u003cli\u003eCondition: Please review all photos carefully before purchasing.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eOriginally developed for space.
