How Much Does Your Favorite Gemstone Cost?

How Much Do Precious Gemstones Cost?


Thousands of jewelry pieces are purchased every single year throughout the globe. Jewelry as an accessory has been worn for over 3,000 years and there’s no sign the trend is going out of fashion any time soon.


However, what has been coming more in fashion recently is gemstone jewelry. Diamonds and Gold are great, but some people prefer an elaborate, beautifully cut tourmaline gemstone rather than tons of sparkles.


So how much do these gemstones cost? It’s difficult to pinpoint exactly, but below is a graph detailing the average price per carat of the most popular gemstones being used in jewelry design today.


As you can see, certain gemstones have a huge variation in price. Why is this? How can turquoise vary from $10 to $1,000 per carat?


The answer is there are many factors that determine the price of a gemstone.


If a stone comes from a rare location such as Tanzanite (which exclusively comes from Tanzania), it is going to be expensive regardless of how large the gemstone is.


Another factor is the structure of the stone, which analyzes how many cracks or veins a gemstone has, how hard the gemstone is, and whether or not it has been enhanced. Generally the more enhanced a stone is, the more devalued it becomes. This is why there is a huge demand for natural rubies, for example.


For Turquoise specifically, is has the more variety when found in nature, as no two turquoise stones are similar. Raw turquoise, meaning turquoise stones that were directly taken from the ground, are incredibly rare and thus bring a heavy price tag.


The color of the gemstone can also greatly effect the price. Tourmaline is an example of a gemstone that comes in many different colors, some more rare and valuable than others. For example, neon-blue tourmaline is the most rare and expensive, while pink tourmaline is the most common and thus, the cheapest.


Other factors that include price include direct sourcing, the mine of origin, and the shape of the stone itself.


Now that we know what goes into calculating the costs, how durable is each stone?


This is another very important factor to consider when buying gemstone jewelry, as the less durable a gemstone, like opal, the more you will need to take care of it to preserve the jewelry’s beauty.


Hardness is measured on the Moh’s scale, a scale of 1-10 that measures the resistance of gemstones and minerals against scratches. The higher the number, the stronger the material.


As with price per carat, the hardness rating of various gemstones can vary widely, as illustrated in the graph below.



Based on the data, if you consider yourself clumsy and always breaking things, perhaps it’s best to go with a sapphire bangle or a ruby leather bracelet that is less likely to break if you drop it.
