Hearts & Arrows Diamonds

A Hearts & Arrows diamond is a visual phenomenon that appears in the finest Ideal Cut round brilliant diamonds when viewed in a gemscope. Diamonds cut with precisely aligned and carefuly shaped facets combined with optimum proportions produce an incredibly brilliant sight, called Hearts & Arrows.

A Hearts & Arrows Ideal Cut Diamond is the ultimate and most brilliant in the world. When a Hearts & Arrows Ideal Cut Diamond is placed in a gemscope, anyone can clearly see the effect of the Arrows in the top view of the diamond, and Hearts from the bottom view.

Beware of diamonds exhibiting a partial Hearts & Arrows pattern that is not crisp and sharp. These are not genuine Hearts & Arrows. Hearts & Arrows are usually found only in diamonds that meet American Gem Society Laboratories’ AGS “0” Ideal Cut requirements. The scope is merciless when it comes to any deviation from perfection. Any detour from the correct path of light will result in the deformation or absence of either hearts or arrows. This device, as unassuming as it may appear, can clearly show even the untrained eye how well or how poorly a diamond is cut.

What is an Ideal Cut Diamond?

The standard grading system which laboratories employ is heavily relied upon by the jewelry industry to provide the most authoritative and accurate information regarding the quality of a diamond. Issued by an independent gem lab, these reports provide a thorough evaluation of each stone and identify the diamond’s imperfections. The information listed is so specific that it an be used to identify a particular stone at a later date.

The American Gem Society (AGS) is the leading gemological laboratory that assigns a cut grade to the round diamonds it examines. They use three factors to determine this grade:

  • Polish – The final finish must be perfectly void of any streaks or marks left over by the manufacturing process.
  • Symmetry – Every facet needs to be of equal size and perfectly opposite its counterpart on the crown and pavilion.
  • Proportions – Ideal proportions are those strict angles and proportions that will maximize refraction and reflection. When proportions are ideal, the diamond will appear whiter because more light is reflected out of the crown. Even diamonds with more color will face up whiter.

The AGS assigns a zero (0) grade to the diamonds that have met “ideal” criteria for all three factors.

A Rating of AGS “O”

A diamond that receives the AGS-O Ideal Cut rating for all three categories (polish, symmetry, and proportions) is commonly referred to by those in the know as an AGS-O Ideal Cut Diamond or a “Triple Ideal Cut Diamond.” Triple Ideal Cut Diamonds are those stones that have achieved the highest standards currently acknowledged by independent gem labs.

Why aren’t all diamonds polished to Hearts & Arrows Ideal perfection?

The answer is time and money. It takes an experienced cutter years before he is able to achieve this level of perfection. In many cases, cutters do not want to cut these elite stones. Being paid by the piece, cutters would rather mass produce inferior cuts for which there is more demand.

Once a master cutter has started polishing a Hearts & Arrows Ideal Cut Diamond, it will take about 2 to 3 times longer to finish than it would an average diamond. He will use his 10X loupe many hundreds of times, and will check his work by computer a dozen times. He will also polish away much more of the original rough diamond than he would if he were cutting a standard stone.

On the average, cutting a Hearts & Arrows Ideal Cut Diamond will require a 15% greater waste of the original material. So, over the course of a year, one can easily imagine the hundreds of hours and extra carats lost to dust that this level of precision requires.

Laser inscription in the girdle allows easy identification of a stone.  The serial number is easily visible through a microscope or even a jeweler’s loupe and increases the owner’s confidence in the diamond.
