Overlooked Gemstones

With the economy still in recovery mode, people are looking for big, glamorous jewelry that has an individual flair to it.  To keep things budget friendly, I’m posting some center gemstone ideas for commonly overlooked gemstones.  I love that all these stones come in large sizes with little price tags compared to the “big three” (ruby sapphire and emerald).

First up is tourmilated quartz.  It’s regular quartz crystal that has tourmaline needles inside it.  Some pieces have a lot and some only have a few slivers.  The best part is that no two are alike.  I think this makes for very unique jewelry even in the most simple settings.




Below that one is rutilated quartz.  Instead of the black to dark green needles, it has gold needles in it.  Quite a conversation starter…







Moonstone exhibits adularesence–a phenomena where the bluish glow floats over the stone when it’s moved.




Blue chalcedony has a very “wedgewood” blue that looks fabulous in traditional and contemporary settings.




Iolite is a fantastic budget replacement for those who love tanzanite.




Bloodstone is overlooked in this day and age.  Perfect for men’s rings it is a very dark green with red spatters.

Custom design is more than creating fantastic settings.  It can be fun to explore new gemstones and create new conversation pieces.

  2. It’s perfect that there are so many photos of these diamonds here, which offers more direct understanding for customers.The design is traditional but the colors are bright and smart.

  3. This book is definitely a great resource to have when you’re buying a diamond. I picked this up near the end of my search, so I had come to know most of the basic diamond information like acceptable table ranges, clarity and color ranges. The photos were extremely helpful because no other source I have come across provides you with full color close ups and defections of inclusions. What’s a knot, feather, facet? What do they look like? Are they bad? *Princess Cut*I was looking for a princess cut diamond (the square one) and unfortunately this book mostly focuses on rounds. That’s important insofar as the acceptable table and depth proportions are slightly different for princess cuts (FYI-get below 80%, around 70% is even better). Don’t disregard the dimensions! At first I only judged size by carat weight, but a lot of that weight can sit below the diamond-hence you want a lower depth percentage. For example, a 2.0 carat princess cut that’s 7.11 x 7.14 will look bigger than a 2.30 carat that’s 6.69 x 7.30. With princess cuts, you also want to be as square as possible-anything with a length to width ratio bigger than 1.04 starts looking rectangular.Another thing to keep in mind is the difference in Gemological Certificates. I found out early that an EGL G SI1 is just not the same as a GIA G SI1. Make sure you’re comparing apples to apples here. There should never be a $1000 difference in price for the same cut, color and clarity. I found GIA much more consistent and rigid than EGL and eventually just ruled out the EGL certified diamonds. Try it yourself: ask to see the same size, color and clarity in GIA and EGL, 9 times out of 10 the GIA is more colorless and has fewer inclusions. …

      Definitely! Everyone has their own opinions on diamond grading laboratories. Being a graduate gemologist, it is easy to lose “the big picture.” GIA grades for cut, color, and clarity are ranges. This means there are better SI1’s out there than others. I like to think of it as comparing tall brunettes. Differences between them is a combination of personal preference, budget, etc.

  6. It seems diamond in pink is becoming popular nowadays.Young ladies are so eager to have one or more on hands.

    • rosediamonds said,

      Yes, the trend really became more apparent after Jennifer Lopez (the singer) received one. FYI: most pink diamonds are mined in Australia. Treated pink diamonds are also available in the marketplace. Natural ones tend to be less saturated in color and more expensive!

  8. The name of moonstone is lovely. Even though the blue color is a bit strange for the moon, the diamond is as pure as the moon which is perfect.

    • rosediamonds said,

      Moonstone exhibits a phenomena called adularescence. The milky sheen of the stone moves with the direction of the reflected light giving it a ethereal glow. There are differing grades of moonstone, the best being more of a bluish with a silvery cloud of adularescence–the most inexpensive will be white to colorless.
