Blue Nile’s Astor Ideal Cut Diamonds Review

Since its launch back in 2017, Blue Nile’s Astor diamond collection has been the apple of many buyers’ eyes. But what is it that draws people towards this collection, and what are the things you should know before committing to your Astor by Blue NileTM purchase? 

In this blog, you’ll find answers to these and other questions, including: 

What is Astor by Blue NileTM

It has long been understood that cut quality is the most important of the 4Cs, as the cut is what determines the brightness and sparkle of the chosen stone.

With the average buyer now having a greater understanding of cut quality, more information at their fingertips than ever before, and greater insight into diamond anatomy thanks to ever-developing technology, it’s unsurprising that super-ideal cut and in-house specialist diamonds are becoming increasingly desirable with buyers all over the world. 

Astor by Blue NileTM is an exclusive diamond collection that’s been expertly curated to showcase the very best cut diamonds in Blue Nile’s extensive inventory. Selected as such due to their brilliance, fire, and scintillation, Astor cut diamonds are amongst the best at reflecting light, therefore providing maximum sparkle in round, princess, or cushion cut configurations. 

 

What’s the Difference between Astor and Other Ideal Cut Diamonds? 

Diamonds selected for Blue Nile’s Astor collection need to meet a number of strict selection criteria in order to qualify, so you can be assured that when shopping in the Astor range, every diamond will meet or exceed the standards you’d expect for a high-quality, premium cut collection. 

When compared with Blue Nile’s standard range, there are a number of ways Astor ideal diamonds stand out: 

  • Brilliance 

Owing to their specific dimensions that allow for maximum light reflection and performance, Astor ideal diamonds offer a stronger and more visible level of brilliance when compared with very good or ideal cut diamonds from Blue Nile or other providers. 

  • Proportions 

A diamond can still be graded with an ideal or excellent cut whilst having proportions that are slightly suboptimal. With Astor, this isn’t the case. Expertly curated, the Astor range features only those with ideal proportions — with diamonds that are too shallow, deep, wide, narrow, or asymmetrical not making the cut. 

  • Symmetry 

Optimal light reflection, sparkle, and brilliance is achieved through a combination of several quality factors — one of which is symmetry. A diamond can only be selected for the Astor collection if it has perfectly aligned and symmetrical facets. 

Understanding these selection criteria provides great peace of mind when shopping from Blue Nile’s Astor collection, as you can rest assured that any diamond you select from the range will have been expertly assessed, saving you time in the research process.

Is Astor Ideal Worth It? 

A key selling point of the Astor collection is that, when shopping within this range, most of the hard work in terms of assessing and comparing the 4Cs has already been done for you, as only the best diamonds in Blue Nile’s impressive in-house inventory make the cut.  Another big selling point is that each Astor ideal diamond is double graded, firstly by the GemEx system to assess light performance, and secondly by the Gemological Institute of America (GIA) — the diamond industry’s most well-respected grading entity.

Astor by Blue NileTM — Not Like Other Branded Diamonds

Astor is simply Blue Nile’s expert selection of the highest quality diamonds in their huge inventory — like a stamp of approval that allows you total confidence in knowing that you’re getting the best.  Searching for your diamond in the Astor collection makes it faster and easier to find a very well-cut diamond that suits your budget, without having to spend hours researching and reading various GIA reports to narrow down your search.  It’s a smart way of shopping for your next investment, allowing you to skip the process of having to screen diamonds for their quality by yourself.  

Final Thoughts 

There are a number of prominent providers that offer an exclusive collection of specially selected diamonds with extremely high cut quality, and all of them attract a premium price due to the level of investigation and expert scrutiny each stone has undergone to remove any doubts about its quality or value.  Astor by Blue NileTM is no different, and you’ll likely pay a premium for an Astor cut diamond versus an ideal or excellent cut diamond from the wider Blue Nile inventory. However, if you’re searching for the best of the best in Blue Nile’s extensive range, the premium that comes with purchasing an Astor diamond is often worth it.
