answers:

All right, most of the above answers are in the right direction. First, try the CLR; it is the best for hard water if it is hard water. Limeaway will also work. If either does not, then you have something known in the glass industry as glass corrosion. It typically does not happen on car mirrors. You can try to buff this out with either the polishing compound or steel wool. Try the compound first. You can also go to a glass shop and ask for some rouge. This is a superfine glass polishing compound. I would guess even a superfine diamond paste used for lapping metals would work. Realize, scratches are a pain to get out of glass. When working with these polishing compounds, use a dremel with felt end tip to work the polish. Use copious water so you don’t burn anything on the glass. Been there, done that.

Good luck

Can a person tell the difference between a cubic zirconia and a real diamond?

Diamond And Jewelry Information

answers:

I can of course, but not everybody is trained to see the diffference.
In daily wear, when you see CZ’s, you will notice they have substantially more fire than diamonds, and the flashes you get from the pavilion when you rock the gem, will be orange, while with diamonds they will be orange and blue . Most easy this difference can be seen in diamonds with some brilliant cut, but when you observe emerald cuts, it gets much more difficult !

Most people wearing CZ’s choose big stones and they usually look like D IF’s, while these are not so common and wear very serious price tags, especially in the over 3 Ct range. Big diamonds are set in platinum, or gold usually, in top quality finished jewelry pieces, while some CZ’s are set in other metals and in lower cost jewelry.

Natural diamonds have some specific differences from synthetic CZ gems.
With a loupe you can see the facet junctions on diamond are sharper due to the higher hardness of diamond. The diamonds get scratched much more difficultly. Polish marks on diamonds run per facet in different directions, while on CZ they usually run all in same direction. Most CZ are also clean, non-included. Inclusions in CZ can be gas bubbles, which are unfound in natural diamonds. Under a UV lamp, a diamond can be inert, or be blue fluorescent (colorless diamonds !). A CZ will be greenish yellow to yellowish orange under longwave UV, yellow under shortwave UV. Easy to detect ! CZ gems will be heavier for the same size as a diamond : specific gravity of diamond is 3.52 while CZ’s is 5.80.
When you put a CZ and a diamond on paper with text, with the table on the paper, you will see that a well cut diamond does not make you see any of the text below, while the CZ a little bit.

Enjoy !

Michael asks…

Is there a to tell if gold is real without taking it to a jeweler? What about diamonds?

Diamond And Jewelry Information

answers:

If you can measure the volume and mass of your “gold” precisely (e.g. – displacement and a mass balance), you can calculate the density and compared with the known value for gold density. If the density matches (or is statisically close enough to match), then you likely have gold. If it is far off, it is probably not gold. Also, you might need to verify the purity of your gold. 24k (pure) gold has a different density than 18k or 14k due to fillers and other metals added to alloy the material.

As for your diamond, no need to attempt to break the diamond. Use a scratch test. Diamond is the hardest natural substance known. Find a real, known diamond and scratch the two together. If the suspect “diamond” is not a diamond, it will be scratched easily, and the known real diamond will not be affected. Else, both diamonds will serve to scratch eachother equally.

Don’t do this to your family heirlooms.

Betty asks…

What are the pros and cons of white gold vs sterling silver for a diamond ring?

I want a sterling silver or white gold ring…which metal is better and why?

Diamond And Jewelry Information

answers:

Actually white gold is not anymore expensive than yellow gold. They are both measured by their percentages of pure gold within the ring. Platnium is very expensive, but gold is gold regardless if it is yellow, white or pink. There are varying qualities of gold.

Silver is softer and will show more wear over time. I have tons of silver and love it, but for a ring, I’d go with gold. With gold, the higher the karat the higher percentage of pure gold within, so the softer it is. 14-18k is good. I have some 24k pieces and they are pretty scratched up because of the softness of the metal.

What’s the best way to clean the air vents over the stove?

they’re really greasy

Diamond And Jewelry Information

answers:

First see whether they can be removed. In my rentals, there are very small diamond clips around the edges holding them into the frame. Once you find the “master” clip and push it in, all of the clips retract and the filter will release from the hood. On my home, the filter has little wires that you bend to release the filter. This enables you to not only clean both sides of the metal filter, but also inside the hood (where you will be shocked to see so much grease).

TayLee is correct about Krud Kutter, I soak my vents in a 3:1 ratio of krud kutter to water in the laundry tub so that the water is high enough to submerge the entire metal vent. Do not use a wire brush on the vents because it scratches the aluminum and can bend the fine wire mesh. A regular stiff dish brush works well to loosen the embedded grease. If your vents are aluminum like mine, do not use any product on them with bleach because it will permanently etch, discolor and pit the aluminum. (learned that lesson)

Inside the hood, I have found krud kutter straight is easiest because it cuts right through it faster. You have to constantly rinse out the grease from the sponge though because once it is full, you will just be spreading it around rather than removing it.

PS The only store carrying krud kutter in my area is Lowes on the cleaning aisle. It comes in a gallon container, can be diluted according to the type of job you are doing, it is biodegradable, non-toxic, fume free and safe for pets and children.
