FAQ : frequently asked questions on Diamonds and Jewelry


The CEO of VMK Diamonds, Mishael Vardi, has over 25 years of experience in the colored diamond trade. VMK is more than just a diamond company; we have been bringing wholesale prices on fancy color diamonds to the online community for over a decade. We offer the winning combination of attentive customer service, staff members who are each experts in their fields, and a premium selection of the highest quality colored diamonds available.
Here at VMK Diamonds, we are committed to perfection and it shows in our precision cutting techniques and meticulous selection process. We carry an extensive stock of fancy colored diamonds in all sizes and shapes. We also specialize in pairing colored and white stones in matching pairs, sometimes hard to find because every single diamond is so unique.
VMK Diamonds holds membership with both the NCDIA (National Colored Diamond Association) and the WFDB (World Federation of Diamond Bourses). When you shop with us you can rest assured that you are working with the best in the business.

Yes. VMK’s experienced gemologist is at your service at any time to assist you with any questions or diamond needs.

The offices of VMK Diamonds are located in the Tel Aviv Diamond Bourse in Israel.

VMK Diamonds does not operate a retail store. This allows us to cut costs and focus completely on bringing you the most extraordinary stones at the best value. We work out of our office headquarters in the Diamond Bourse in Tel Aviv, Israel.

We believe that you should actually be able to examine and fall in love with your stone before you buy it, and that is why we offer viewings at many different locations around the globe.


VMK Diamonds only deals in 100% natural diamonds, delivered straight from mother earth to your collection. None of our diamonds have been laser treated, color enhanced, clarity enhanced, or modified in any way.
For additional assurance, every diamond that we sell is GIA certified (Gemological Institute of America) which guarantees that it is natural and untreated.

We do not carry any synthetic jewels at all.

The diamonds used in jewelry as side diamonds and accents are categorized as diamond melee, the term used for brilliant cut diamonds under .18 carats in weight.

Diamond melee is quality graded in three groups: commercial, promotional, and collection. Collection grade diamond melee consists of D-F color and supreme clarity, making it the highest quality available. VMK Diamonds uses only collection grade diamond melee in our jewelry and custom designs.

The vast majority of our stones are GIA certified. The diamonds in our Argyle Pink collection from the Argyle mines are independently certified by them, but GIA certification is available upon request.

Any jewelry we sell is accompanied by a full jewelry appraisal. Although smaller side diamonds and diamond melee (like in a pave set ring) are not usually individually certified, they are laboratory appraised and certified as part of the entire jewel.

Every appraisal includes:

- A fully accurate description of the jewelry.- A photograph of the jewel embedded on the appraisal certificate.- Estimated retail value that can be used for insurance and resale purposes.- The stones’ color, clarity, and carat weight.- The stone’s shape (e.g. pear, asscher, round, emerald, etc).- The metal quality of the setting when applicable (e.g. 14k, 18k, platinum, etc.).- Stamp of the certifying agency (e.g. GIA, GRA, IGI, etc.).

We do everything in our power to ensure that none of our diamonds were obtained by way of human rights violations, child abuse, violence, or unsafe mining conditions. All of our diamonds are purchased from reputable sources and from countries that are known to employ ethical practices in their diamond industry.

As a member of WFDB (Member #IDE4789), and supporter of the Kimberly Process, we are held accountable for every one of our diamond purchases, whether rough or polished. We maintain a zero-tolerance policy toward blood diamonds.

Any diamond that you can view on the VMK Diamonds website is available for purchase. Please note that a diamond’s availability may change very quickly due to the high demand customer volume.

Diamonds are forever and so is our commitment to customer satisfaction. That’s why every VMK diamond or jewel is eligible for a free cleaning every 6 months. You can also return your jewelry to our office for any maintenance needs, like prong tightening, rhodium plating and re-polishing.

Contact our customer service representative to arrange your services.

White gold is given its pure white color by a process that plates it with rhodium. The rhodium plating can wear off over time, displaying the gold’s true buttery white color. We offer lifetime free rhodium plating on all of our jewelry to keep it looking like the day you bought it.


Although all of our diamonds and jewelry comes with a lifetime warranty, we do not provide insurance. We do, however, provide an appraisal that can be used for insurance purposes.
