When was the First Recorded Use of White Gold?
Use of white gold has been reported by historians to go back as far as the
1890s. In Christie Romero's research ("Warman's Jewelry, 2nd Edition),
she reports that in 1915, Karl Gustav Paul Richter of Pforzheim, Germany
was granted a patent for a white gold alloy( gold, nickel and palladium).
White gold is not thought to have been available commercially until about
1917.
Do Sonic Jewelry Cleaners Work?
Home units are fine for diamonds and most gemstones. Instructions should
be followed to the letter. Pearls, opals, malachite, turquoise, coral,
lapis, emerald and tanzanite should never be cleaned in a sonic
cleaner. Be careful not to over load the machine so that items bump up
against one another. When push comes to shove you're really better off
(safer) having your jeweler clean your fine jewelry!
What's the Difference Between Karat with a "k" and Carat with a "c"?
This can certainly be confusing. Karat with a "k" refers to the percentage of precious metal in a piece of jewelry (e.g., 14K, 18K). For example, 10K gold means that ten parts of gold and fourteen parts of alloy make up the total metal content. Keep in mind that pure gold is 24 karat. Incidentally, an alloy is a mixture of two or more compatible metals which are, in turn, combined with gold. The results are a new metal which is harder and more durable than pure gold.
Carat with a "c" refers to the weight in a gemstone, i.e., 1.50 carat, 1.75 carat. One carat is 100 points, so if you have a .75 carat stone, it is considered three-quarters of a carat or 75 points.
What's the Best Way to Store Jewelry When Traveling?
Diamonds will scratch one another as well as other jewelry. Instead of
placing all your jewelry into one pouch, put each piece into a separate
plastic bag and then put all the bags into one pouch.
