Lapidary Crafting and Jewelry Making

The best thing for you to do is take the bracelet to a jeweler to have a quick test done, to determine if the bracelet is silver or actually the more valuable 9K white gold.

I say this because "375" is the European gold content hallmark for 9 karat / 9 carat gold.

BTW, if the bracelet were sterling silver the hallmark would read "925".

Hope this helps... :)

You'll have to define "fco"... I've never heard the acronym used in the jewelry business.

It is a red gemstone and costs around 90000 to 100000

Dollars? Weights?

Jasper is a stone used in jewelry. It comes in many colors including blue, red, orange, black, brown, green, gray, or yellow.

The beautiful clear colorless doubly terminated quartz crystals called "Herkimer Diamonds" found near Herkimer, NY, can very quickly be removed from their hard rock matrix with a hammer and chisel. A diamond bladed saw would ensure a greater likelihood of success; even little diamond blades on a Dremel or Foredom tool will do. (Protect your lungs and eyes!) Bear in mind that nice crystals in matrix are more interesting, and more valued by collectors than crystals that have been broken off the matrix.

The Diamond Veneer is a process whereby treating Cubic zirconia with a film of Carbon Diamond particles. This Nanoscale Coating over Cubic Zirconia creates a veneer of carbon diamond that is crystallized around the entire stone. This process results in a flawless "G-K" color on the diamond color scale.
Another advantage of the Diamond Veneer process is that the vaporization process under extreme heat and pressure conditions, significantly increases (4-5-times) the fire, refraction and durability of the CZ, rendering it impossible to detect as CZ.

Most gems, like malachite do not have a widely accepted grading system like diamonds do, so terms like "AAA grade" are relatively meaningless and more clever marketing than anything else. One seller's purported "top quality grade AAA" material might be very different from anothers. Generally, what you're seeking in top grade malachite is material that has good bright color, contrasting banding, attractive patterns, no soft spots, no cracks, no pitting, and no inclusions of other minerals. An exception to the latter would be when malachite is combined with azurite, which makes for a fabulous and colorful gem.

Reputable stores and jewelers usually set CZ in no higher than 10k gold, and they are stamped as such. The CZ is on the inside of the band by the gold stamp.

However, anybody can buy loose stones and settings separately and have them set. So, if a person wants to buy a 14k gold setting and set a medium Cubic Zirconium for the center stone, and small surrounding diamonds, they are still saving a lot of money and the 14k stamp and surrounding diamonds make it look more authentic. There is no law that says a layman can't do this. "Name" jewelers have reputations to protect so I doubt they would 'mix them' like that.

From the http://wiki.answers.com/ehistory.htm#Middle%20Kingdomuntil the latter half of the http://wiki.answers.com/hdyn18a.htmfinger rings consisted generally of a loop of cord or metal and a swivel bezel, often a scarab, that revolved on the loop. Rings with the loop and bezel in one piece, made of metal, semiprecious stones, or faience, were uncommon until the http://wiki.answers.com/featurestories/amarnaperiod.htm, when they seem to have become fashionable. Fifteen rings, some with swivel bezels, were found on Tutankhamun's mummy, but only two were actually placed on his fingers; the remainder were bound in the linen wrappings, five over the right wrist and eight beside the left wrist. In addition, eight rings, which the ancient robbers had inadvertently left in the tomb wrapped in a piece of linen, were found in a gilded chest in the antechamber, where they had no doubt been placed by the necropolis staff. Five of these twenty-three rings are illustrated here; they are all made of gold and in every case the bezel is in the form of either a single or a double cartouche.

Rough diamonds are made to sparkle by the process of faceting. The stone is held against a rotating flat lap that is charged with diamond dust, and ground to a very precise shape, chosen to obtain the best yield. Finer and finer grades of diamond powder are used to finish and polish the individual facets. It's a very precise and slow business.

the number stamp of 925 on a piece of jewelery means 92 1/2 parts of sterling silver,so the number 925 on jewelry means sterling.

I was researching this myself and I found a company called, "Saigon Jewelry Holding Company (SJC). They deal with gold and silver. I found this information on website www.tradekey.com.
