Platinum jewelry has taken a little change over the past few years, especially since the price has risen along with Gold.
In order for the industry to keep prices competitive, they have started to classify Platinum Alloys with the 800pt or 850pt marks etc - which is quite acceptable as they are NOT using the word 'PLATINUM' (which indicates the pure metal).
While that term (800pt) may be a little misleading, especially if it were not brought to the purchasers attention, it is never-the-less quite acceptable.
You also have to remember that not all jewelry is made in the States and many items made in Europe or overseas may not have such stringent rules and regulations.
Personally, if your friend knew the item was 800 grade alloy and was happy with the price - I'd be happy with that.
Regarding Platinum verses White Gold - White Gold is HARDER because of the way it is mixed with other metals. Traditionally Platinum is used for diamonds because it doesn't throw any colour into the gemstone. Diamonds are graded by their LACK OF COLOR so the less reflection from the ring - the better. Platinum wins for me, but it's still a personal thing.
For those who are born in the month of January, they should be familiar to their birthstone, which is garnet. It is a wonderful stone with great properties and a variety of uses. It is recognized as the birthstone for January and is used as a gem for jewelry, but it is also a material that is used in industrial processes.
Garnet is a wonderful gemstone that comes in many different shapes and colors. But there is more to garnet than being a birthstone of January. Let's take a look at some of the facts about this wonderful gem.
The Uses of Garnet
Garnet is considered to be one of the most, if not the most versatile gems in the world market today. The use of garnet can be traced back to the ancient times, particularly the Bronze Age, when it was primarily used as an abrasive and a gemstone. Today, industrial garnet is far more valued in aggregate terms than gem garnets. The production of garnet for industrial processes is at least 50 times bigger than the production of gemstone garnet.
The first documented use of garnet for industrial processes can be traced back in 1878, when Barton Mines Corp. manufactured it as a coating for sandpaper. Today, aside from being an abrasive, it is also used to cut steel in water jets under high pressure. States like Alaska, California, Arizona, Colorado, Montana and Idaho have wonderful sources of garnet.
