The term “generic silver” refers to wholesale silver products, which means silver products that have been already used, like generic silver rounds or bars. Highly experienced investors know that when purchasing silver bars, the real value of the investment is the silver content itself and its purity.
Also to know is, which silver coins are the best investment?
With that in mind, here is a list of the top ten best silver coins for investment.
- Silver American Eagles.
- Silver Canadian Maple Leafs.
- APMEX 1oz Fine Silver Rounds.
- Morgan Silver Dollars.
- Austrian Silver Philharmonics.
- 7. “ Junk” Silver Dimes.
- 8. “ Junk” Silver Quarters.
- Mexican Silver Libertads.

Current Silver Gram Bar Values
|Description||Silver Value (USD)|
|20 gram silver bar||$10.63|
|50 gram silver bar||$26.58|
|100 gram silver bar||$53.17|
|1 kilogram (kg) silver bar||$531.77|
One of the most common questions for those new to buying silver bullion is: What is a silver round? The answer: Silver rounds are privately minted coin-shaped silver pieces, produced by private mints. They are not referred to as coins because they are not government minted nor are they legal tender.
How to Tell if a Diamond is Real with Water
- Get a glass and fill it with water. It doesn't matter what type of water you use.
- Drop the diamond into the glass of water. Due to the high density of a diamond, when dropped into water it will sink. If the diamond floats to the top or middle of the glass, it's fake.
Since, Diamonds get their brilliance from three things: reflection, refraction and dispersion. Reflection is the light that hits the diamond and is immediately bounced back up, giving it an instantaneous shine. Hence diamond never shine in dark or until and unless light comes on it.
ilovebutter/Flickr The way that diamonds reflect light is unique: Inside the stone, the diamond will sparkle gray and white (known as "brilliance") while outside of the gem, it will reflect rainbow colors onto other surfaces (this dispersed light is known as "fire"). "They do sparkle, but it's more of a gray color.
If a diamond has fluorescence, it will glow to some degree under a "black light", a fluorescent light. Here, again, the reason is because the boron in the diamond is stimulated by ultra-violet light. The presence of fluorescence in diamonds is considered good when it enhances the appearance of a diamond.
Fluorescence refers to a diamond's tendency to emit a soft colored glow when subjected to ultraviolet light (such as a "black light"). Roughly 30% of diamonds fluoresce to some degree. Colorless (D-F) fluorescent diamonds sell at up to a 15% discount since the fluorescence is perceived as a defect.
Colorless. While there are differences in color between D, E, and F diamonds, they can be detected only by a gemologist in side by side comparisons, and rarely by the untrained eye. D-F diamonds should only be set in white gold / platinum. Yellow gold reflects color, negating the diamond's colorless effect.
For example, most white diamonds are discounted in price when more yellow hue is detectable, while intense pink diamonds or blue diamonds (such as the Hope Diamond) can be dramatically more valuable. Of all colored diamonds, red diamonds are the rarest.
Diamond Clarity Grade Chart
- FL & IF. Flawless, Internally Flawless. Under 10x magnification, inclusions are not visible, rarest clarity grade.
- VVS1, VVS2. Very, Very Slightly Included.
- VS1, VS2. Very Slightly Included.
- SI1, SI2. Slightly Included.
- I1. Included.
- I2, I3. Clarity grades not carried by Blue Nile.
The most popular range is the VS1-VS2 diamond. In diamonds over 1 carat (where clarity is more important, and SI2 inclusions are often easier to detect), an SI2 is often half the price of a VS1 diamond. About one third of diamonds sold fall into the SI1-SI2 range.
Consumers generally prefer brown diamonds in medium to dark tones with a warm, golden to reddish appearance. They generally show a hint of greenish, yellowish, orangy, or reddish modifying colors. Yellow is diamond's second most common fancy color. Yellow diamonds are sometimes marketed as “canary.”
In white colorless diamonds the obvious answer is D (the diamond color chart goes from D-Z). But in colored diamonds While there can be debates about which is more expensive, the blue diamond or the pink diamond, there are no debates as per which colored diamond is the most expensive –
The following 10 gems are the world's rarest and most valuable gemstones.
- Poudretteite. First discovered in the 1960s in the Poudrette quarry of Mon Saint Hilaire, Quebec, Poudretteite is one of the rarest gems known today.
- Black Opal.
- Red Beryl.
Ruby Value. Rubies are the most valuable members of the corundum family. Large gem-quality rubies can be more valuable than comparably sized diamonds and are certainly rarer. There is a relative abundance of smaller, 1-3 carat blue sapphires compared to the scarcity of even small gem-quality rubies.
Source: English Wikipedia. (PhysOrg.com) -- Currently, diamond is regarded to be the hardest known material in the world. But by considering large compressive pressures under indenters, scientists have calculated that a material called wurtzite boron nitride (w-BN) has a greater indentation strength than diamond.
Actually Titanium is not stronger nor harder than a good grade steel, the only advantage it has over steel is the fact it is a much lighter metal with similar to steel qualities. Though it doesn't even come close to a Diamond in strength or hardness.
Below are the 10 strongest materials known to man:
- #8 Nanospheres / Nano-Kevlar.
- #7 Diamond.
- #6 Wurtzite Boron Nitride.
- #5 Lonsdaleite.
- #4 Dyneema.
- #3 Metallic Glass.
- #2 Buckypaper.
- #1 Graphene. One-atom-thick sheets of carbon are 200 times stronger than steel.
That's about the same amount of energy in 10 trillion trillion billion megaton bombs! These explosions generate beams of high-energy radiation, called gamma-ray bursts (GRBs), which are considered by astronomers to be the most powerful thing in the universe.
In a study set to come out this month in the Journal of the Royal Society Interface, British researchers announced that the teeth of shelled, aquatic creatures called limpets are the strongest biological material on Earth, overtaking the previous record-holder, spider silk.
