Gems - diamonds, rubies, emeralds, sapphires - just need to be cleaned and polished. They already exist in a usable form (after you cut and polish them.) You just need to wash the dirt away. \n\nOres are big piles of dirt that have bits of metal (iron, lead, silver, gold) in them. You have to refine the metal out and melt it into bigger pieces. It is a little like evaporating salt water to get salt.

Dubai\n\n\nAs one of the world's fastest-growing regions, construction cranes are an omnipresent sight on the horizon, making that buzz all too literal. But word-of-mouth about the potential for doing business here is equally strong, helping to make the 10th edition of the International Jewellery Dubai (IJD) show, which started Monday and concludes on Friday, Dec. 10, double in size over last year's event.\n\nThe show includes 454 exhibitors this year, up from 225 exhibitors in 2003. A greater number of first-time international participants (including Diamond Trading Co.(DTC) sightholders from Belgium and the Far East, as well as 27 companies exhibiting in an Italian Trade Centre-sponsored Italian Pavilion) reflects the region's growing importance to the international jewelry community.\n\n"As the figures indicate, IJD has grown tremendously in stature, and while it is already the most significant show of its kind in the region, it is now set to take its place among the premier shows serving the jewelry trade on the world stage," says Christina Nicholson, general manager of exhibitions and conventions for the Dubai World Trade Centre, the organizers of the show. \n\n"With Dubai playing an increasingly important part in the worldwide gold and jewelry trade, thanks to its strategic position and strong trade ties with the region, an exhibition like International Jewellery Dubai has tremendous scope for growth," Nicholson says.\n\nThe show's expansion comes as no surprise in this city, where the most common remark focuses on the shocking degree of change that's transformed Dubai from a desert outpost into a bustling capital of commerce. It is considered the hub of the Gulf region, now the third largest diamond market in the world, after the United States and Japan, according to DTC figures.

Synthetic boules have been available since the 1890's (the reason sapphire/ruby synthesis was originally attempted).  There books by John Sinkankas which address this topic, the primary answers being color, orientation, appearance under magnification.  Any decent rock show will have people who can id it by sight, check this link for the nearest one.\n\nhttp://www.rockhounds.com/rockshop/table.shtml\n\nAny competent jeweler, without a financial incentive, should be able to tell you this.  I would be sure they are GIA certified in colored stones, or simply contact the GIA itself:\n\nhttp://www.gia.edu/\n\nPrice and/or setting is no method of determining if a stone is natural or not, in that even major retailers are selling fakes at full price these days.

That's about to change! The cost to manufacture synthetic diamonds is continually going down to the point now where the diamond mining companies are getting worried, especially since the "imitation" diamonds are more perfect than the real thing!\n\nBut we can't say the same thing about gold. Nobody knows how to make gold yet and it's currently over $600 an ounce and going higher.

I am not sure who produces the most.  It is my opinion that Ireland produces the best.

Emeralds are Beryl, which has a hardness of 7.5 to 8 and can certainly scratch glass. Glass is silica, with a hardness of 6 to 7.\nDiamond, the hardest of all substances, gets the big 10. \nBeryl has been found in about every color of the rainbow, but green is most common.

"Carat" is the unit of mass to measure fine stones.  It's just like any other term of measurement.  Just happened to be named Carat.\n\n"Karat" is the unit of measurement for the proportion of gold in an alloy; 18-karat gold is 75% gold; 24-karat gold is pure gold

Diamond. It is pure carbon.

Yes it is gold but not emeralds. The green stones are malachite\nthe FIFA World Cup Trophy, was first presented at the 1974 World Cup. Designed by Silvio Gazzaniga, it stands 36 cm tall and is made of 5 kg of 18 carat (75%) solid gold with a base containing two layers of malachite, and depicts two human figures holding up the Earth. The name of the country whose national team wins the tournament is engraved, together with the year, in the bottom side of the trophy. It is not known whether FIFA will retire the trophy after all of the name plaques at the base are filled in; this will occur after the 2038 World Cup.\nFIFA's regulations now state that the trophy, unlike its predecessor, cannot be won outright: the winners of the tournament receive it on loan for four years and receive a replica to keep.

There is not.  Unlike gold/silver, diamonds are very abundant.  Their price is manipulated and controlled by DeBears.  I would not invest in any type of instrument such as you are describing.\n\nDebears regularly adds/subtracts from the market for specific types of stones depending on what challengers are trying to do.  Ie if a country tries to sell diamonds outside of Debear's pricing mechanisms/controls.  You could easily get killed with such an instrument.
