Crafted By Infinity Diamonds Review

What Makes a Crafted by Infinity Diamond?

Founded by Paul Slegers in 2001, Crafted by Infinity is a diamond cutting boutique based in Antwerp, Belgium. The vision of the company is simple: to maximize performance in every rough diamond they polish.

Being a small outfit, Crafted by Infinity produces a very low volume of 1000 diamonds every year compared to other cutting houses. This has to do with being extremely selective of their rough diamonds, the proprietary planning involved and the skilled labor required in their manufacturing process.

On their official website, the company claims to craft diamonds with 3D precision which yields visual results that “exceed every known performance metric”. In fact, they go as far as to say that their diamonds have achieved “levels yet unmeasured and ungraded by diamond laboratories”.

Speaking from experience in the industry, whenever a business makes such bold marketing claims, the skeptic in me will instantly be asking:”Really?”. This is because most other vendors I had reviewed often fall short on their claims upon scrutiny of their products.

Are Infinity diamonds really as good as they claim to be? Is it really true that every CBI diamond displays identical cutting standards of the highest level? In today’s review, we will take an indepth look at their diamonds using tangible data and physically examine a loose CBI diamond… is the exclusive online retailer for Crafted by Infinity diamonds.

Review of Crafted By Infinity Diamonds

Whenever I review a line of diamonds from any specific vendor, one of the methods I employ is to randomly select diamonds across different specifications and price points.

The rationale behind doing this is simple.

It enables you to critically examine consistency and reveals how the company operates their business. Speaking from a consumer’s perspective, you would want to see the same level of craftsmanship and quality across the entire inventory (i.e. a $500 CBI diamond should have identical cut quality compared to a $100,000 CBI diamond). 

With that said, let’s take a look at three random loose diamonds chosen for the purpose of writing this review. (In truth, I actually looked through hundreds of their diamond listings).

The magnified face up views above are taken under diffused lighting conditions (with obstruction). These images provide you with an idea of the diamond’s contrast patterning.

ASET – AGS Light Performance Analysis

The Angular Spectrum Evaluation Tool (ASET) is a scientific tool developed by AGS for light performance analysis. Using different color bands colors to represent intensity of light return, contrast and leakage, the ASET allows you to quickly analyze a diamond’s optics.

A quick explanation of the ASET is provided below and you can perform your own analysis using the reference charts here:

Red: intense light return – red is generally what you want to see.
Blue: contrast – important for contrast and scintillation. Blue areas should be as symmetrical as possible.
Green: less intense light return – keep green areas minimal.
White: light leakage – keep white areas minimal.

If you look at the ASET images of the CBI diamonds, they all display optimal areas of reds, greens, blues and whites. Upon scrutiny, I can tell you that these 3 diamonds are very consistent in terms of light performance.

Idealscope – Light Return Analysis

Compared to the ASET, the Idealscope is a much simpler tool and serve a similar function of indicating a diamond’s light return properties. Here are what the various colors mean:

• Red: indicates light return.
• Black: contrast – important for pattern & scintillation. Black areas should be symmetrical.
• White: light leakage – keep white areas minimal.

Again, all 3 diamonds display fantastic levels of light return based on their idealscope images. Feel free to utilize the reference charts here to perform your own comparisons.

Hearts And Arrows – Cut Precision And Optical Symmetry

The hearts and arrows images reveal the degree of craftsmanship and precision that the polished diamond has. In a diamond that is cut to extreme precision, you will see the formation of crisp hearts and arrows patterning.

As seen above, all 3 Crafted by Infinity diamonds display well-defined patterning which is only possible when every individual facet is carefully planned and positioned.

For the discerning shopper who is looking for the best of the best, you will be pleased to know that Crafted by Infinity ticks all my checkboxes when buying super ideal cut diamonds. Check then out for yourself here!
