Often I am asked what is the ‘largest’ and ‘most expensive’ sapphire? The largest sapphire in the world is probably still well protected underground, and maybe it is a billion karats or more, but will it be a ‘fine’ sapphire?  That is very doubtful.  What is rare and costly in a sapphire is a combination of its color, clarity, size, cut and of course...

As a company which specializes in natural untreated sapphires we often receive letters from our customers.  The answers to their questions I feel are beneficial to anyone who is interested in purchasing gemstones. Recently we received this letter: Hello:  I recently purchased a stone through you and I am quite happy with it. I do have...

Flawlessly setting a gorgeous natural untreated sapphire in a simple yet elegant pendant can result in a fantastic gift idea that your significant other will cherish wearing around her neck daily.  To crazy or bulky of a design can take away from the true beauty of the sapphire, and can end up just being another...

I’ve just joined the Natural Sapphire Company to help develop and update our print and web materials.  I’ll be writing mostly about the new graphic designs we’ll be creating here at NSC.  While I’ve worked with a motley crew of companies in all different sectors, I’d never had the chance to work with such an...

In this post I will try to make some sense of the colored stone grading. One of the most important things to...

I love sapphires, there is no doubt.   You can have all the colors of the rainbow,  except of course red, because then it would be a ruby.  One of my favorites though,  is the yellow sapphire.  There are many assortments of the color yellow from lemon peel, pastel yellow, to bright sunflower yellow.  If you...
