What's the difference between a diamond wholesaler and a diamond retailer? 

In general, a diamond retailer sells individual products to the public, whereas a diamond wholesaler sells large quantities to retailers.  Motek Diamond is a special breed; as a diamond wholesaler, we sell diamonds in bulk to retail stores across the nation but we also sell individually to the public in the Dallas - Fort Worth metroplex. This allows us to pass the savings on to you, without any middlemen in the process. Also, retailers are open on weekends whereas wholesalers are closed on weekends, in order to allow our retail customers to work to their best capacity without any interruptions. Motek Diamonds by IDC is a true diamond wholesaler; we manufacture and cut our diamonds in our factory in Israel (Izakov Diamonds Israel). Read more about us here.


What’s the difference between Ideal Cut And Excellent Cut grades?

Different grading labs have different grading systems. The Gemological Institute of America (GIA) grades their cuts from Poor - Excellent. Alternatively, E.G.L (European Gemological Laboratory) grades their diamond cuts from Poor - Ideal Plus. 

Ideal cut also refers to the make of the diamond (the way it was cut). Read more about diamond cut here.


Does the cut of the diamond have any effect on the price?

The cut of the diamond is a major factor in determining the diamond's value. If a diamond is cut poorly, the diamond will appear dull and the price would significantly drop compared to a diamond with a Very Good or Excellent cut.



Carat is a unit of measurement by which a diamond is weighed. Karat is the measurement that shows the purity of the gold.

Can I see the difference from one color or clarity grade to the next?

It is very difficult for the average person to determine the difference between one color or clarity grade from another, especially without the proper equipment. Even a skilled gemologists would find it hard to determine a one color or clarity difference in a diamond without the proper equipment and lighting. More so, if a diamond is set in a ring or any other jewelry, it makes it especially difficult. In order to check a diamond's clarity, one would have to use a loupe, or in some instances, a microscope, in order to determine the correct clarity. In general, clarities that fall in between F-VS2 (and even SI) may be impossible to detect with the naked-eye. In order to determine a diamond's color, proper lighting is crucial. Also, diamond dealers and jewelers use a "master set" which contains sample diamonds with all the colors, which are used in order to determine a diamond's color.


What is fluorescence, and how does it affect a diamond?

Diamond fluorescence, in its most simple form, is the effect that ultraviolet (UV) light has on a diamond. Fluorescence is the visible light that a diamond emits when it is exposed to the UV rays. Of the diamonds submitted to GIA over the past decade, approximately 25% to 35% exhibit some degree of fluorescence. However, only 10% of those show strengths of fluorescence that may affect appearance (i.e., strengths noted on laboratory reports as medium, strong, or very strong). As blue is the complementary color to yellow, the most common tinted color in diamonds, blue fluorescence can make yellowish diamonds look white or colorless. Studies show that for the overwhelming majority of diamonds, the strength of fluorescence has no widely noticeable effect on appearance. A diamond that fluoresces has the same integrity as one with no reaction to UV.


What is a clarity enhanced diamond?

There are two main techniques for improving a diamond's clarity; laser drilling and fracture filling.

Laser drilling is commonly used to remove small dark inclusions. The laser bores a small hole into the diamond's interior and burns away the inclusion, or creates a channel through which a bleaching agent can be introduced to improve the inclusion's appearance.

Fracture filling hides white fractures in a diamond called "feathers." A glass-like substance is injected into the fracture to make it less visible and to improve the stone's apparent clarity. Because the filling may be damaged or removed during routine cleaning and repair, the technique is controversial. Good fracture filling is very subtle, and so examination by a skilled diamond grader is necessary to detect its presence in a stone.


Why are there no A,B,or C color grades?

You might wonder, why do diamond color grades start with "D" color as the most colorless grade, and not start with "A"? Well, many moons ago, approximately 80 years ago, there wasn't a uniform color grading system in place and there were many different terms used (A, AA, 1, 2, etc.). In the 1940's, GIA came along and decided they were going to start the grading system fresh with an unused term, so they decided "D" would be the highest color. To this day, it is widely accepted to use GIA's grading scale, but there are other gemological laboratories (EGL, AGS) which still use their own grading systems.


How do I know I'm getting what I bought?

There are multiple ways Motek Diamonds reassures you will get what you are paying for. First, each diamond we sell comes with a certificate (unless diamond is uncertified) from a reputable lab, which will show all the diamond specifications. Second, each diamond jewelry purchase comes with a written appraisal. The written appraisal is a document which specifies all the specifications of the jewelry, such as karatage, diamond quality and size, along with a monetary value to show you and your insurer what the jewelry is worth. We also have a 30 day diamond exchange policy, so if you are unhappy with your purchase for any reason, we'll replace it with a different diamond of your choice (additional fee may be applied). Motek Diamonds is an established diamond wholesaler for over 40 years, so you can always feel comfortable knowing that you'll have a place to go back for all your diamond needs.


What is the difference between GIA & Other certifications?

Generally speaking, GIA is far more expensive than other certifications since it is considered as the most stern laboratory. Moreover, GIA is a non-profit organization, so it is believed they do not have any hidden agendas or interests when grading diamonds. Although, it must be borne that there are many GIA certified diamonds which are off by more than 2 grades.  Read more about diamond certification here.
