CUSHION
A square or rectangular stone with rounded corners and deep crown facets, found almost exclusively in antique jewellery.
OLD CUT DIAMOND
Refers to a stone cut with a circular shape and large culet. These stones were cut to maximise light return in low light conditions predominantly prior to 1910. Also called an old European cut.
RUBY
One of the most valuable gemstones on earth, ruby is regarded as the stone of passionate love. From the corundum family, the red variety being ruby and the blue, sapphire. With the exception of the diamond, corundum is the hardest of the gemstones on the Mohs scale scoring a 9. Ruby is derived from the Latin "Ruber" meaning red. It has long symbolised eternal devotion and romantic love.
Old MineThe term 'old mine' refers to gemstones deriving from historical, often ancient, mining sources.
With regards to diamonds, for example, this would indicate that the stones were mined in India or Brazil, the two primarily mining locales prior to the discovery of diamonds in South Africa in the late nineteenth century. India in particular is renowned for diamonds mined in the central area of the subcontinent surrounding the city of Golconda, and are known for their particularly high quality in terms of size, colour and clarity. The Hope diamond and the Koh-i-Noor, perhaps the two most famous diamonds of all time, are Golconda diamonds. To add to the rarity of such stones, these mines have been largely exhausted.
In the case of emeralds, stones classified as old mine would be from Egypt, Austria, Gandahara (the ancient central Asian kingdom) or, primarily, Colombia. The highest quality old mine emerald material derives from this last source, which had been mined by pre-Colombian tribes for approximately one thousand years. It was not until the Spanish presence in the New World in the early sixteenth century, however, that these stones graced the royal courts of Europe, the Middle East, and, primarily, India.
CTIn reference to gemstones, an abbreviation of carat, a unit of weight. One carat is equal to 0.20 grams.
In reference to gold, also an abbreviation of carat, a unit of purity or fineness of gold and gold alloy, expressed as a number out of 24 parts by weight, e.g. '24 carat' signifies pure gold, '18 carat' 18/24th gold in the alloy, et cetera.
Originally derived from the carob seed, called quirat in Arabic, a seed of naturally uniform weight.
