Product Description

Enhance the stereochemistry of your earlobes with this racemic pair consisting of a (1R)-(+)- and a (1S)-(–)-camphor ear stud. Almost as globular looking as pearls; yet, still optically active in a most attractive way: Beautimous maximus! You will not only impress Gustaf Komppa, but anyone and everyone, including the most nerdalicious.

Camphor (Japan Camphor, Laurel Camphor, Gum Camphor, Camphire, 1,7,7-Trimethylbicyclo[2.2.1]heptan-2-one) possesses a highly distinctive aromatic, slightly minty and medicinal odor. It is obtained as colorless crystals either from α-pinene by acid-catalyzed Wagner–Meerwein rearrangement via a non-classical 2-norbornyl cation, reaction with sodium acetate, hydrolysis and oxidation, or by crystallization from the essential oil of the Camphor tree (Cinnamonum camphorta (L.) J.Presl.), which is native to China and Japan, and closely related to cinnamon. Since it was so easy to isolate from camphor oil, it was amongst the first pure perfumery raw materials ('Scent and Chemistry – The Molecular World of Odors', Verlag Helvetica Chimica Acta/Wiley-VCH, 2012, p. 6). Camphor occurs in many other natural products, in both enantiomeric forms, and even as racemate. Yet, (1R)-(+)- and (1S)-(–)-camphor cannot be distinguished by their repective odors, nor by their detection odor thresholds ('Scent and Chemistry – The Molecular World of Odors', Verlag Helvetica Chimica Acta/Wiley-VCH, 2012, p. 128). The reason may very well be their globular shape, which made John E. Amoore coin a camphoraceous primary odor for globular-shaped odorants ('Scent and Chemistry – The Molecular World of Odors', Verlag Helvetica Chimica Acta/Wiley-VCH, 2012, p. 73). It comes as no surprise that van-der-Waals surface models of (1R)-(+)- and (1S)-(–)-camphor look like little pearls, and thus are ideally suited for the design of ear studs. Still they are chiral and will form a stereochemically matching pair with each earlobe.

The dimensions of a single camphor ear stud is ca. 1.7 cm × 0.7 cm × 0.7 cm. The post length is ca. 11 mm, and its diameter is ca. 0.9 mm. It extends in both enantiomeric forms from the C(4)–H bond on the trisubstituted bridgehead. Two alternative locking notches are set 3.5 mm and 2.0 mm from the end, allowing for two different fitting modes. Designed to be 100% compatible with the Thomas Sabo butterfly clips Z881 (Art. No. 4051245085808, 18k gold-plated) or Z355 (Art. No. 9120700857498, Sterling silver), but also working with a great variety of other earring backs (earnuts).
