In the captivating the world of precious stones, the ruby is the acknowledged ruler. For thousands of years, ruby has been measured as one of the most expensive precious stones on Earth. It has the whole thing an expensive stone should encompass: glorious color, exceptional hardness and outstanding brilliancy.

Ruby is the red diversity of the mineral corundum, one of the sturdiest minerals on globe, of which the sapphire is furthermore a variety. Pure corundum is colorless.

For this cause, rubies of more tha n 3 carats in volume are very atypical. So it is no marvel that rubies with scarcely any additions are so expensive that are in good colors and superior sizes. they accomplish top prices at marts, surpassing even those rewarded for diamonds in the similar category.
Historical and cultural references :
According to Rebbenu Bachya, and the New International Version, the word odem means "ruby" in the verse Exodus 28:17 (referring to a stone on the Hoshen), and was the stone representing the tribe of Reuben. Modern Hebrew has taken this meaning. However, odem actually means earth, and is cognate with Adam; in the Middle East, the earth it refers to is certainly reddish, but the Septuagint translates the term as sard (which also means red), which is also the name of a common, somewhat opaque, gem. Scholars think the stone intended is probably a sard, as does the King James Version, scholars think that if not a sard it may possibly be the related gem carnelian; it is possible that sard and odem here just mean the colour of the stone, and red jasper would therefore also be a possibility.
Ruby is the most commonly named precious stone in English translations of the Bible; an example being Proverbs 31: "A virtuous wife is more precious than rubies.". The underlying masoretic text doesn't necessarily refer to rubies, however. Not only are there issues such as that mentioned with odem, but in the case of Proverbs 31, the masoretic text merely states jewels, and the Septuagint makes Proverbs 31 refer to precious stones (estin lithon ); some English versions of the bible believe that pearls is a better translation here. An early recorded note of the transport and trading of rubies arises in the literature on the North Silk Road of China, where in about 100 BC rubies were carried along this ancient trackway moving westward from China.
