types of diamonds


Diamonds…  one of Mother Nature’s dazzling nuggets.  Treasured since ancient times, there is nothing that captures light and brilliance more than a well cut, natural diamond. 

The most beautiful diamonds are thought of as luxury items, well outside of most people’s reach.  But is this really true?  Is this a myth? We suggest you read on to see the answer!

Did you know that there are affordable, natural alternatives to a traditional diamond?  Of course, there are stones such as moissanite and zirconia, but they wear over time and are not “the real thing.”

With advancements in technology, there are certain natural diamonds that can undergo processes to improve color or the appearance of clarity.  So why would you want to learn more about these types?  The answer is simple.  To save money while still knowing that you own a natural, beautiful diamond that can be treasured for a life-time at an affordable price!

There are 3 types of diamonds that have come on to the market and have proven the test of time:  GIA Certified Natural HPHT Diamonds, Laser Drilled Diamonds, and Clarity Enhanced Diamonds.  In this review we will go over the characteristics that make them ideal choices for couples getting engaged and investors alike.  They are in order of price per carat value from high to low.

1) GIA Certified Natural HPHT Diamonds: 

Not to be confused with synthetic, lab-grown diamonds, GIA certified natural HPHT diamonds are show-stoppers that are increasingly sought-after by sophisticated diamond buyers and investors.  It is notable to mention, in 2019 there was a 36% in jump in these HPHT beauties being set in engagement rings

Natural HPHT diamonds are desirable for their remarkable beauty and permanence.  It is rare to see an HPHT stone with less than VVS2 clarity or F color.  The clarity is intrinsic, coming out of the earth with extremely high clarities and superior molecular structure.  So superior, these types of diamonds (Type IIa) are strong enough to withstand a process that mimics being put back in the earth’s immense heat and pressure to change their off color appearance.  There is no chemicals, dyes, or radiation used. Just immense pressure and heat.

The reason GIA certified natural HPHT diamonds are so desirable is because they are stable and the upgrade in color will last a lifetime. 80% of these diamonds will be colorless. Only GIA and other credible labs have the sophisticated instruments to detect if the diamond is a natural type 11a diamond. 

We wanted to get the GIA’s opinion on HPHT diamonds.  They are the foremost and most credible authority in the industry holding up stringent guidelines to educate and protect diamond consumers.  The following outlines an email and their expert response:

Question:  Hello, I’m curious about HPHT diamonds – are these considered natural diamonds or synthetics?

GIA response:  HPHT is a process used to alter the color of natural diamonds. Natural diamonds can be turned into shades of pink and yellow.

 If it is a HPHT synthetic diamond, the diamond will receive a synthetic diamond grading report: http://www.gia.edu/gem-lab-service/synthetic-diamond. For any synthetic diamond submitted to our lab, if it has not been laser inscribed with the phrase Laboratory Grown, we will inscribe it ourselves before returning it to the client.

 When a HPHT processed color natural diamond is issued a GIA diamond grading report, first you will find one of two laser inscriptions on the girdle of the diamond:

1) HPHT Processed or

2) The registered trademark that is exclusive to diamonds that have undergone the HPHT process.

 If the diamond was submitted with the registered trademark already inscribed, we will not add HPHT processed to the girdle.

 For a diamond in the D-to-Z range, under comments it will note the laser inscription and the following: “The diamond has been processed by high pressure high temperature (HPHT) to change its color.

 If the diamond is a colored diamond, in the color section of the report, under Origin, the color will be listed HPHT Annealed. In the Comments section, it will have the statement from above. It is considered stable so that is why we will issue grading reports on these diamonds.

Conclusion: HPHT diamonds will save the buyer a minimum of 35%. Larger the diamond, grater the discount! 

The key take-away points here are a)  GIA certified natural HPHT diamonds receive a natural diamond grading report (versus a synthetic diamond grading report) and b)  Natural HPHT diamonds are considered stable, that is why the GIA issues grading report on these types.

So what does a GIA certified natural HPHT diamond look like? Answer: exactly like all other natural diamonds of the same size, color and clarity!  Before contacting Hadar Diamonds for an in-home preview at no charge or obligation, watch the videos below to witness the beauty:



 2) Laser Drilled Diamonds

What is a laser drilled diamond?  Laser Drilled (LD) stones are those that have had a noticeable dark inclusions removed by a microscopic laser to improve the appearance of clarity.  The thin laser (smaller than the diameter of a hair) strategically targets the black carbon spot often from the bottom of the diamond.  The channel the laser creates is then used to “wash out” the tiny pieces of the inclusion with a solution.  A common question with laser drilled diamonds is “Can the channel the laser created open a space for dirt to get into the diamond?”  The answer is no, the channel is so miniscule that dirt cannot enter the stone. 

Another question is “How much can laser drilling improve the clarity of an included stone?”  Typically, the clarity can be improved by one grade.  So, for example, if you have an SI2 diamond, it can be improved to an SI1, or in rare cases, even a VS2. 

What does this mean for you?  It means that you can pay for a diamond that had lower clarity, while having the permanent appearance of a grade or two more.  All, while still knowing you are wearing a natural diamond that requires no special care.  Laser drilling is a permanent process and the upgraded clarity will remain the same forever.

Conclusion: Laser drilled diamonds will save the buyer a minimum of 40%. The larger the diamond the greater the discount!

3) Clarity Enhanced Diamonds

Clarity enhancement remains to be the most often misunderstood processes of all diamonds - especially with all of the misleading articles on the internet and fierce competition in the diamond market!  The information on clarity enhanced (CE) diamonds can be overwhelming.

While it is true that clarity enhanced stones with deep enhancements are not suitable for purchase in our opinion, clarity enhanced diamonds when processed correctly are an excellent alternative if you are looking for a larger diamond at an affordable price.

Deep enhancements can signify a dangerous stone. This type of stone will show a red line where the filling was applied, or a faint reddish purple rainbow look.These red lines indicate a deep enhancement that can fall out easily. While clarity enhanced diamonds by nature are priced lower than HPHT and laser drill diamonds, it is important to understand what “sounds too good to be true.”  There are two caveats. Enhanced diamonds with a filling should not be exposed to harsh chemicals. When your ring requires sizing, tell the person doing the work to remove the diamond and reset after the ring is sized.

When done well by enhancement experts, clarity enhancement is a reliable and proven method to beautify a diamond that may have had a “whoopsie” when cut. 

Diamond cutters are human and can make very expensive errors while cutting a stone.  The cutting wheel moves very fast and is slippery, and naturally, every once in a while the cutter will slip and create a superficial, tiny scratch on the surface of the diamond.  While it’s no picnic for the cutter to admit it happens and suffer the financial loss of an error like this, it does occur.  However, what you didn’t know, is that it can work to your benefit to afford a bigger diamond for less.

After the scratch, commonly known as a “feather,” is analyzed, the cutter will decide if it is fit for enhancement.  (By the way, not all are).  From here, the diamond is taken to enhancement experts to improve the clarity of the stone by means of filling the feather with a diamond-like substance.  This can essentially restore a diamond back to its original clarity appearance prior to the whoopsie the cutter may have inadvertently made.

Conclusion: Clarity enhanced diamonds with a filling will save the buyer a minimum of 50%. The larger the diamond, the greater the discount!
