Gemstones are rare and highly prized objects of beauty. As well as their application in jewellery and ornaments, gemstones form an important part of museum-based geological collections.
FindYourStampsValue.com is pleased to let our readers know that Australia Post is showing off Australian gemstones in a new stamp issue. The philatelic items feature four stunning Australian gemstones: golden sapphire, rhodonite, pink diamond and fluorite. Nowadays they are held in the mineral collection of the Australian Museum, Sydney.
Throughout human history gemstones have been valued and used for personal adornment and ritual practice. As well as being objects cherished for their intrinsic beauty, gemstones have been – and continue to be – valued as symbols of wealth and status. Over the ages, the cutting of gemstones has evolved from a limited practice into a complex art that uses sophisticated technology to reveal a mineral’s hidden beauty.
To be transformed into gemstones, minerals must possess hardness (resistance to scratches and general wear), measured on the MOH’s scale; beauty, defined by colour, clarity, lustre; and rarity. Some arresting minerals that are too soft or fragile for wearing as jewellery are faceted into “collector stones”, in which the art of the expert cutter has overcome the constraints of the mineral to present the stones as aesthetic objects for collectors.
The gemstones shown in the stamp designs are in the collection of the Australian Museum, in Sydney. The golden sapphire and the pink diamond represent precious gemstones that are cut and polished as possible centrepieces for exquisite jewellery. The rhodonite and the fluorite exemplify stones that are valued as collector stones, rarities transformed by lapidaries into singular specimens for the pleasure of gem specialists.
