Ruspoli Sapphire
The Ruspoli Sapphire, also known as the Wooden Spoon Seller's Sapphire, is a 136.9 carat (27.38 g) blue sapphire that has historically been confused with Grand Sapphire of Louis XIV (which has also been called the Ruspoli Sapphire or Wooden Spoon Seller's Sapphire). Recent research has shown that not only are these two separate gems, but also that the story of once being owned by the Ruspoli family and having been acquired from a wooden spoon seller in Bengal are both apocryphal tales with no basis. The origins of this confusion stem from a book published in 1858 by Charles Barbot, who confused the Ruspoli Sapphire with the Grand Sapphire of Louis XIV.. The known history of this sapphire begins with a French jeweler named Perret, who sold it to a jeweler from Milan named Antonio Fusi around 1811. A dispute over the sale was settled by a court-ordered auction in 1813, leaving a clear paper trail of this gem's history. From there it passed through the hands of a well-known Parisian ...

Carat (unit)
The carat (ct) is a unit of mass equal to or 0.00643 troy oz, and is used for measuring gemstones and pearls. The current definition, sometimes known as the metric carat, was adopted in 1907 at the Fourth General Conference on Weights and Measures, and soon afterwards in many countries around the world. The carat is divisible into 100 ''points'' of 2 mg. Other subdivisions, and slightly different mass values, have been used in the past in different locations. In terms of diamonds, a paragon is a flawless stone of at least 100 carats (20 g). The ANSI X.12 EDI standard abbreviation for the carat is CD. Etymology First attested in English in the mid-15th century, the word ''carat'' comes from Italian ''carato'', which comes from Arabic '' qīrāṭ '' قيراط , in turn borrowed from Greek ''kerátion'' κεράτιον 'carob seed', a diminutive of ''keras'' 'horn'. It was a unit of weight, equal to 1/1728 (1/12) of a pound (see Mina (unit)). History Carob seeds ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hope Diamond
The Hope Diamond is a diamond originally extracted in the 17th century from the Kollur Mine in Guntur, India. It is blue in color due to trace amounts of boron. Its exceptional size has revealed new information about the formation of diamonds. The stone is known as one of the Golconda diamonds. The earliest records of the diamond show that French gem merchant Jean-Baptiste Tavernier purchased it in 1666 as the Tavernier Blue. The stone was cut and renamed the French Blue (''Le bleu de France''); Tavernier sold the stone to King Louis XIV of France in 1668. It was stolen in 1792 and re-cut, with the largest section of the diamond appearing under the Hope name in an 1839 gem catalogue from the Hope banking family. The diamond has had several owners, including Washington socialite Evalyn Walsh McLean, who was often seen wearing it. New York gem merchant Harry Winston purchased the diamond in 1949, touring it for several years before donating it in 1958 to the Smithsonian Nation ...
