FAQ

1. What does the word “treatment” mean with reference to fancy color diamonds?

It’s best to avoid treated stones (to enhance or change color), and stay with natural colors. That being said, you should be aware of the type of treatment techniques that can be found on the market today.

  1. HPHT – an irradiation technique that combines high pressure and temperature – this technique is used to produce yellow, pink, brown and blue diamonds.
  2. Heat Treatment – used to create black diamonds - usually used for low quality diamonds.
  3. Infusion Technique – a non-permanent color that penetrates into the stone.
2. What is color origin - does it have something to do with rough or polished diamonds?

When it comes to being secure about the color origin of the fancy colors that you buy from me, I would like to reassure you that I only buy natural fancy color rough diamonds; and, because of the expertise that I have developed – and actually my passion for NATURAL fancy colors, I can take responsibility for all aspects of the buying, cutting and polishing process, and, therefore, guarantee that the color of all the diamonds that we deal with is a NATURAL color formed deep within the core of the earth. 

3. When it comes to the certification, why is Natural the most important word on the grading report?

When you are checking the certificate for details about fancy color diamonds, it is very important that the word “NATURAL” appears on the diamond grading report !

You might ask why I think the word ‘natural’ is so important when it comes to describing the color of the diamond.

There are a number of reasons, but nowhere is it more important than on the certificate, the grading report, that comes with the diamond.

  • It’s really for your protection and a matter of confidence with reference to fancy colors.
  • Because the word NATURAL with reference to color is the important factor when determining the value of the color of the diamond.
  • The certificate is the best proof that you will have that the diamond has not undergone any type of treatment to enhance the color.
  • Natural fancy color diamonds are rare in nature and are found in a limited number of mines around the world.
  • Their price is significantly influenced by a number of factors including the density and hue of the color.
4. What is personal branding? Are you a family business?

Why Seren?

There are lot of very prominent companies (not only in the diamond business) that are known worldwide under their family names.

Their names have become brands indeed! These brands also had a beginning and their stories of success have been always encouraging me. I've been cherishing this idea (since I was very young) and of course when it came to business, I had no doubt about it.

Today, in the diamond business, the name Seren is associated with complete trust and reliability. First of all, we are very accurate about the stones that are coming to our stock. All our suppliers know that in case the stone (rough) purchased from them doesn't get "Natural color origin" (for any reason) after it has been polished and graded by the GIA, it will be returned to the supplier.

In this way, we can pass on the same secure feeling to our customers as they know that we are taking full responsibility for the origin of our goods!

When it comes to Seren Diamond – everyone (in the business) knows that we are one of the top sources for the most amazing and rare natural fancy color diamonds on the market today.

When it first came to branding our company, it was very important for us to emphasize the concept that all of our diamonds are natural (because a number of new techniques to enhance colors or make colored diamonds that were being developed - that were becoming increasingly harder to distinguish from the natural stones- unless you had the expertise and experience of dealing with natural fancy colors that we have); therefore, we decided to guarantee the color origin and take responsibility for the diamonds we cut and polish.

Pipeline integrity is a priority for Seren Diamond and that is this idea that stands behind our company’s motto as well – "Natural Color from Depths of Nature"!

5. How are fancy color diamonds graded?

Natural Fancy Colored diamonds are graded based on the following criterion:

Hue:  yellow, orange, brown, blue, green and red. The color hue is the dominant color of the stone.

Intensity: intense, vivid, etc. Usually, the higher the intensity is – the more rare and more expensive diamond is.

The color tone. This applies to how much the stone is dark or light, it can be graded from dark to very dark, from light to very light. When grading natural fancy colour diamonds, the GIA uses nine grade categories:

  1. Faint
  2. Very Light
  3. Light
  4. Fancy Light

When natural fancy colored diamonds are graded, they can be given a grading that consists of a hue and a tint, for e.g. Fancy Intense Bluish Green that means that the color intensity is intense, the main color is green, but it has a touch of blue.

7. What is the WFDB Mark and why was it important for you to put it on your internet site?

I think that it is actually about consumer confidence, even though it is a trademark within the diamond industry and jewelry trade, because it is a symbol that includes text that indicates that it is individual, and it belongs to a registered WFDB bourse member, and it features the member’s registration number.

The WFDB Mark includes a brief slogan, listing the 3 elements that members of the jewelry trade should be reminded of when they see the WFDB Mark: Tradition, Integrity and Accountability.

 The WFDB Mark is a trademarked logo, which approved members of World Federation of Diamond Bourse-affiliated diamond exchanges are able to display to clients and suppliers, to confirm that they abide by the World Federation Code of Principles. A bourse member is able to display the WFDB Mark as long as he or she is in good standing.

The WFDB Mark is brand that will set bourse members apart by indicating that they belong to a WFDB diamond exchange. Like any brand, the WFDB Mark has to promise something that the client is looking for. In this case, we are talking about tradition, integrity and accountability, which together provide clients with confidence in the bourse members’ businesses and in the products they sell.

The World Federation’s Code of Principles, or WFCOP, is a set of better business principles, similar to those being promulgated by the DTC and other organizations. The WFDB has been debating the various ethical issues for many years, and for just as long has been formulating policies to ensure that members of its bourses operate within an ethical framework. Issues addressed include HPHT treatments, conflict diamonds, synthetic diamonds, child labor, health conditions in the workplace, disclosure and non-disclosure, fracture filling, laser drilling, and the removal of laser inscriptions from a girdle. The WFCOP is a stand-alone document that clearly lists the conclusions drawn from the various relevant resolutions passed by the WFDB.

What sets the WFDB’s Code of Principles apart from the others in the industry is the fact that for the use only of members of WFDB diamond exchanges, it is one of only a handful of ethical business systems that can be properly monitored and audited. Indeed, while a number of organizations have introduced sets of Best Business Principles, almost none have managed the more difficult task of creating systems for auditing, monitoring and enforcement. The WFDB has had such a system in operation for years. Every one of its affiliated bourses has a judicial system in place, and decisions taken at one bourse can be enforced in all its sister bourses.
