Is this gemstone valuable? A quick guide.

So what factors should I look at and consider when determining if a Sapphire, Ruby or Emerald for example is valuable or not?

Much like diamonds and the four C's, coloured gemstones are valued on a variety of different factors. Within each type of gemstone there are a vast number of qualities. They can look shockingly different and that is reflected in the vast difference in what you can expect to pay for them.


The most desirable, often due to their beauty and the rarest are the most valuable. Just like that rare sport's car or watch when there is high demand but low availability prices sky rocket.

But how does that actually translate when looking at these stones? Or maybe more relevantly if you want a really high quality, stunning Sapphire, Ruby or Emerald what sort of things should you be looking for? This short list can give you an idea.

  • 1) Colour/hue - generally speaking a pure, intense colour. Not pale or a mixture of colours.
  • 2) Transparency - not cloudy or dull but really crystal clear and sparkly.
  • 3)  Inclusions - as free as possible from any type of mark inside the stone. (Real gemstones do come completely free from inclusions but not always. This is one factor that is key when detecting fakes!)
  • 4) Shape, size and quality of the cut - not as critical as the actual quality of the stone but none the less very important, particularly size!

This is aimed to be a brief over view. Please take great care when buying any gemstones without professional advice. There are many pitfalls and it is easy to be fooled.
