Diamond IQ Answers:

(No Fair Peeking ahead!)

Ready, Set… GO!


Answer 1)

Blue-White Diamonds are Graded A, B, and C?

False – There is NO A, B, or C in the Diamond Color Grading Chart! The Chart actually starts with D. Plus, Blue-White is an Old Diamond Term that should NOT be used today. It was Misleading and Misrepresentative of the “Blue” in a Diamond, often caused by the presence of Fluorescence.

Answer 2)

A Yellow Diamond looks even MORE Yellow in a Yellow Gold Mounting?

True – A Yellow Diamond will appear more Yellow in a Yellow Gold Mounting (since it picks up the hue), BUT, since everything is Yellow, the Diamond tends to blend in and not be so obvious! :)

Answer 3)

Round Diamonds are always the FIRST Cutting Style from the Parent Rock?

True – The Round Brilliant Cut Diamond is the Most Popular Cutting Style, and so, those Shapes are Cut First!

Answer 4)

An “Ideal” Diamond Cut is the BEST Cut you can get?

False – “Ideal” is a roughly used term that can have wide variances… The BEST Cuts, are the True Hearts, Signature Series, and Hearts on Fire! The ones where the Diamond will Display “Hearts” and “Arrows” under a Special Scope! Those patterns are the BEST!

Answer 5)

Princess Cut Diamonds should always have 6 Prongs?

False – Princess Cut Diamonds have 4 Corners = 4 Prongs! But… Those Prongs SHOULD BE V-Tipped, versus just Regular Round Prongs! Just to be More Secure and Safe and Protect those Vulnerable Points. :)

Answer 6)

Chocolate Diamonds are TRUE “Fancy Colored Diamonds”?

True – They are Real Fancies! Just like these Fancy Cut Diamonds HERE! :)

Answer 7)

Most of the Diamonds on the Market have Eye-Visible Flaws?

True – Half the Market is made up of I Clarity Diamonds, meaning “Included” or “Eye-Visible” Inclusions! :)

Answer 8)

Certified Diamonds are the BEST Diamonds you can buy?

False – Many people think this, but it’s far from the truth. If a Diamond is Certified, it only means that it’s been Evaluated by an Independent Diamond Grader, that’s all. Any Diamond Quality can be Certified, Good or Bad!

Answer 9)

GIA stands for: Gemological Institute Association?

False – Close, but no call. GIA stands for: The Gemological Institute of America.

Answer 10)

Marquise Cut Diamonds look like a Kite?

False – It actually looks like a Football! (See Here) :)

VS Clarity means Very Small Inclusions?

False – Although most of the times people refer to it as such… The Correct terminology is: Very Slightly Included.

Answer 12)

F Color is a Fine White Diamond?

False – F Color is a “Pure White” Diamond. A “Fine White” Diamond is G or H Diamond Color.

Answer 13)

The Average Engagement Ring Purchase is between $1,000-$3,000?

True – Most couples spend up to 3 Grand for “The Ring!

Answer 14)

The more Diamonds you have, the more the Ring will cost you?

False – This is actually the reverse… The more Diamonds you have, the smaller they get, meaning, the Ring actually gets Cheaper. As in Halo Mountings, Pave Mountings, and Illusion Settings. :)

Answer 15)

Marilyn Monroe created the most Iconic Jewelry Phrase ever?

True – Marilyn Monroe (as Lorelei Lee) sang “Diamonds Are a Girl’s Best Friend“, in the 1953 Film “Gentlemen Prefer Blondes“.

Answer 16)

A Diamond that’s NOT Certified, can be easily Grade Bumped?

True – If the Diamond does NOT have paperwork, as in a Diamond Report, it can easily be “Bumped” in both Color and Clarity, and no one would know it. Which is why it’s always important to Buy Certified, and the “Best” Certificate you can get is GIA!

Answer 17)

Tradition says, that Engagement Rings always need to be Diamond?

False – Tradition just says a Ring or Band needs to be worn on the 4th finger of the left hand. Nothing else! :)

Answer 18)

There are NO Cut Grades for a Radiant Cut Diamond?

True – There are only Cut Grades for Round Brilliant Cut Stones, not any of the other “Fancy” Cuts.

Answer 19)

The Most Inexpensive Diamond Shape is the Cushion Cut Diamond?

True – This is correct to a point… If you compare EXACT Quality of Stones, meaning the Same Cut, Color, Clarity and Carat Weight, Cushion Cuts will most likely be the Cheapest (usually HALF the Price)! See some Wonderful Cushion Cut Diamonds HERE!

Answer 20)

93 Points is still considered a 1.00 Carat Diamond?

True – Diamond Carat Weights can Vary by at least 7 Points one way or the other and still be considered on the mark. A 93 Point Diamond, is considered a “Light Carat“, and will look the same size as a Full Carat, but it will be Much Cheaper! :)

Answer 21)

J Color has NO Visible Yellow Hue whatsoever?

False – J Color is at the Bottom of the Near Colorless Chart, and in most cases, you WILL be able to see a Yellow Hue or Cast to it!

Answer 22)

All SI1 Clarity Diamonds look alike?

False – Diamonds are like people, they all look different. Each Diamond will have it’s own Unique Flaws and Characteristics. Just look at the variety of SI Clarity Diamonds HERE to see how different they all appear.

Answer 23)

I3 Clarity Diamonds are Cheaper than VS2 Diamonds?

False – It also depends on the Color, the Cut, the Carat Weight, the Polish, the Symmetry, the Fluorescence, and the Certification of the Stone… They all have a Role to Play in COST!

Answer 24)

A Chipped Diamond is Worthless?

False – Diamonds can be Re-Cut or Re-Polished to remove that Chip or Blemish (most times). Which also means, Chipped Diamonds can be Traded in or Sold. For the Diamond still has Value!

Answer 25)

Blue Colored Diamonds are created from the waters of the Caribbean Islands?

False – Diamonds are made from Heat, Pressure and Carbon. The Color is introduced from Impurities that Mix with the Stone during Creation. The “Blue” Color in Fancy Diamonds is caused by the Presence of Boron.

Answer 26)

Diamonds are made out of 100% Lava Rock?

False – 100% Carbon! :)

Answer 27)

Diamonds can Wear Down, Dull Up, Tarnish and Scratch after 40 years?

False – Diamonds are the Hardest, Most Natural Substance on Earth, but they can Chip, Crack, or even Tarnish, due to Mistakes made by MAN! Which means, it could happen anytime, anywhere!

Answer 28)

If a Diamond is Cut “Excellent“, it will Sparkle like crazy, no matter what?

False – The Sparkle of a Diamond can be Hindered by a Low Color, Inclusions, Cracks, Bad Polish, Poor Symmetry, Fluorescence, or even if the Stone is Dirty! They all HELP or HURT a Diamond’s Sparkle!

Answer 29)

The “Polish” Grade determines is the Diamond comes from Poland?

False – The Polish Grade is how Smoothly Polished the Surface of the Diamond is…

Answer 30)

Diamonds over 1 Carat hold their Value?

False – Diamonds often Lose their Value, no matter what Size they are. They are not meant to be “Investments“. Only “Investments” in your Relationship! :)

Answer 31)

Diamonds can Float on Water?

False – Diamonds are so Dense, they will SINK to the bottom!

Answer 32)

Black Spots in a Diamond are caused by Facet Blind Spots?

False – Black Spots are usually “Carbon“, sections of actual Diamond that didn’t Crystallize properly.

Answer 33)

Lines inside a Diamond mean that the Diamond is Cracked?

False – Most Lines in a Diamond are “Feathers“, or “Inclusions” that give the impression that the Diamond is Cracked. If a Diamond really IS Cracked, it will normally look more like Busted Glass!

Answer 34)

It’s Cheaper to Buy Diamonds online?

True – Online Dealers, like James Allen and Blue Nile, don’t have the Overhead that Brick and Mortar Stores have.

Answer 35)

If your Diamond doesn’t Shine like it used to, it probably just needs to be Cleaned?

True – Get yourself a Jewelry Cleaner or a Steam Cleaner, and keep your Diamond CLEAN! It’ll Shine like the day you bought it! :)

Answer 36)

Step Cut Diamonds are Shaped like a Pyramid?

False – Step Cuts are Cuts like the Emerald Cut, and Asscher Cut Diamonds.

Answer 37)

You should keep your Diamonds away from Bleach and Harsh Chemicals?

True – Bleach won’t HARM your Diamond persay, BUT… It will Harm the Prongs and Mounting holding in your Stone! It will make them Brittle, Frail and WEAK! So Avoid Bleach, Remove your Rings when you do Laundry!

Answer 38)

One of the Most Famous Diamonds in the World, is actually CURSED?

True – The Most Famous Diamond is the Blue HOPE Diamond in the Smithsonian Institute. And yes, it’s been Cursed for Centuries! :)

Answer 39)

The most Important C, of the 4 C’s, is Carat Weight?

False – The #1 4C is CUT! Because Cut Makes Everything Better… It makes the Clarity look Better, makes the Diamond look BIGGER, and makes the Diamond look Brighter, Whiter, and Sparkle more! CUT MATTERS! This is why I always advise “Excellent Cut Diamonds!

Answer 40)

Diamonds mined in Russia, tend to be more Brittle than ones mined in Africa?

False – All Diamond DNA is the SAME, no matter where it comes from. They all have the SAME Hardness and Attributes. :)

Answer 41)

The Best Hearts and Arrows Diamonds have D Color?

False – The BEST Color is whatever Color YOU LIKE! Hearts are Arrows are the BEST Cut… But Color is Subjective. I prefer Pure White Diamonds, but many like Near Colorless. It doesn’t change the Hearts and Arrows, just changes the Body Tone of the Stone.

Answer 42)

A Diamond Plot is a Microscopic Photograph of the Flaws in a Diamond?

False – A Plot is a Diagram, a Drawing of the Inclusions in the Stone. Like a Map of the Flaws! :)

Answer 43)

If a Diamond has Fluorescence, it will Glow in the Dark?

True – That’s what Fluorescence is… It will GLOW under a UV Light (like a Black Light)

Answer 44)

A Stone Cut Too Deep, will make the Color Darker?

True – The Deeper the Stone, the Darker the Color will be (Not a Good Thing when it comes to Diamonds). Which is why most other Gemstones, like Sapphire, Ruby and Emerald, ARE Cut Deeper than Diamonds, to Bring Out, or Accentuate the Color! Because that’s what people look for in Colored Gemstones: Color! :)

Answer 45)

A “Fish-Eye” is when the Culet is Too Large, and it looks like an Eye-Ball?

False – A Fish-Eye is when the Diamond is Cut TOO Shallow, and the Girdle is Reflected around the Table, giving it a Fish-Eye Appearance.

Answer 46)

The Average Diamond Color on the Market, is Near Colorless?

True – Near Colorless is G-H-I-J Colors, and they make up most of the Market. It all has to do with Availability… There’s an Abundance of them. Pure-White Diamonds (D-E-F), are more Rare and more Expensive to Locate. :)

Answer 47)

You can’t see Flaws in an SI2 Diamond with the Bare Eye?

False – You can’t see them FROM THE TOP VIEW! If you turn an SI2 Diamond Sideways, YOU WILL SEE FLAWS! That’s why SI2 is a borderline stone… It sits directly in the middle between Diamonds that Do have Visible Flaws, and ones that Don’t!

Answer 48)

If you buy a Diamond with 23 Diamonds, all 23 should be Certified?

False – That would cost you a FORTUNE! It costs anywhere from $50-$300 to Certify Each and Every Stone… Which is why, generally, only the Center Bigger Diamond is Certified!

Answer 49)

If the Diamond is Certified, it doesn’t matter WHO, or WHERE, you buy it from?

False – Certificates can be Altered, Fake, Falsified… I would only buy from Reputable Stores and Dealers like James Allen and Blue Nile. And, I would also ONLY BUY GIA!

Answer 50)

The Best Clarity to have is always FLAWLESS?

False – Flawless Diamonds have ZERO Inclusions in the Stone. NONE! Which means, it will be virtually impossible to identify that Diamond as YOURS under a Microscope. I always recommend Diamonds of VS or SI Clarity… Ones that you can see something under 10x magnification. Because that way you can Identify your Diamond and keep yourself from getting ripped off or Diamond Switched!

BONUS Answer 51)

Replacement Values should always be listed on a Diamond Report?

False – NO Replacement values should EVER be on a Diamond Report (GIA Certified Diamonds don’t have a Value listed). A Report is for Factual Information about the Grading and nothing else. Values should be saved for an “Appraisal” which goes to your Insurance Company! :)

BONUS Answer 52)

The Best “Diamond Guarantee“, is to actually get your Diamond Insured?

True – That’s the ONLY Guarantee! Because so-called “Guarantees” (found in mall stores) come with many Requirements and Rules. Which are too easy to “VOID!” Plus, “Guarantees” Don’t cover is the ring is LOST, STOLEN, or DAMAGED! So get it Fully Insured to Cover Everything on the Ring and Diamond. Just in case! :)
