June 2019 Newsletter: Romantic Pink Sapphire

 Pink Sapphires are nearly as rare as rubies and are sought after by collectors, especially for special occasion jewelry like engagement and anniversary rings. One reason is that pink sapphire can have a similar look to the very expensive pink diamond, with excellent brilliance and sparkle. But pink sapphire is not only more affordable than pink diamond, it can also be found in larger sizes and with much better color saturation.

Sapphire and Ruby are aluminum oxide by chemical composition, the different colors result from traces of other minerals. Pink sapphire, like ruby, is colored by traces of chromium; and the greater the concentration of chromium, the deeper the pink color.

Pink sapphire ranges in color from a pale pink to coral pink to purplish pink and reddish pink. The presence of titanium adds a bluish hue, yielding a purplish pink. An exceptionally rare pink-orange color is known as Padparadscha. Pinkish-red corundum is usually called Ruby, but the dividing line between Pink Sapphire and Ruby is fuzzy.

Colors of Pink Sapphires

Pink sapphire, like Ruby, tends to have some inclusions. In general, Ruby and Pink Sapphire will tend to have more inclusions than blue or yellow Sapphire. Thus a Pink Sapphire graded as eye clean (no inclusions detectable by the unaided eye) would count as a very clean specimen. Most Pink Sapphire is heated to improve the clarity or reduce the purplish secondary hue.

The classic sources for Pink Sapphire are Sri Lanka (formerly Ceylon) and Burma. More recently, fine stones have come from Africa, especially from Madagascar, where major deposits were found in the late 1990's. Some of the best Madgascar material occurs in rare large sizes (over 2 carats) with excellent color saturation.

Client Story: A 20.12 ct Black Star Sapphire Ring

20.12 ct Black Star Sapphire set in 14k Gold

A client in California sent us the photos above and shared her experience working with us on a recent jewelry project:
My ring arrived today right on time, and it was extremely well-packaged, thank you.
Ron  … I don't have words to describe how stunning this ring is. It is actually beyond what I imagined, to be honest. This is something I'll never forget in my life. You see, I am 34 and I have really never been interested in jewelry whatsoever, until I saw a random Star Sapphire online somewhere and I was mesmerized. And then, within days, I discovered your website. By then I had looked at hundreds of Star Sapphires, but that 20.12 carat Star Sapphire video was obvious love at first sight. I knew I had to have it without question, but I had no idea what to do with it or how to make it into a ring. But you guided me through all of it, and I just couldn't be more impressed and thankful for the overall experience. You literally turned my dream into a reality!
Thank you for taking the time to make videos of your excellent stones, because that really makes a difference.  I may not have noticed that stone had it not been for the video. And please, please give the jeweler my praise and thanks as well.  He/she is incredibly talented... the ring is flawless!
Please let me know if you would like me to leave a review somewhere online, because I am more than happy to endorse your services. And of course you have my permission to publish anything I've said on your site. I will always be keeping an eye on your inventory, and you can be sure that if something else strikes me, I'll be in touch!!!

Could you explain the difference between cabochon and faceted gems? Is it just a difference of cutting style? PT, Canada

It is a difference of cutting style, to be sure, but not only that. In general, high quality transparent gem material will be cut with facets, while translucent or opaque material will be cut in the smooth domed shape known as a cabochon. So "cabochon-grade" material is considered to be lower grade than "facet-grade" material.

However, there are important exceptions to this general rule. Gems that display a star (asterism) or a cat's eye (chatoyancy) are always cut as cabochons. Some of these cabochons are quite valuable, such as especially fine Star Ruby or Star Sapphire or Cat's Eye Chrysoberyl or Alexandrite.



All the best in gems,
