What determine the price of coloured gemstone?
Paraiba tourmaline from Brazil, is just one of the many examples why gemstone is rarer than diamond. The price of a intense vivid neon paraiba, can cost three to four times the price of a 1.0ct quality diamond!
In the world of coloured gemstone, we study different aspect in individual gem. Colour, Origin, Enhancement, Carat, Clarity, Cut, each of these affect the value in the gemstone.
Unique Colour in gemstone
With colour being the most crucial point when we acquire gemstone. From pastel to medium and intense vivid colour shade. Usually the case where value in the gem increases according to the colour intensity.
Many believe that the rich bluish green in emerald, is the most beautiful green you ever seen. The best green sapphire or tsavorite garnet can never be comparable to emerald green. Every gemstone has their own unique colour in them.
Origin and Enhancement
In the grading for major gemstones, such as Ruby, Sapphire and Emerald. Origin and Enhancement are key pointers that affect their value tremendously. Take for example, a royal blue Kashmir sapphire can price many times more than a royal blue sapphire Sri Lanka. Unheated pigeon blood red ruby, can price double the price of a heated pigeon blood red ruby.
Enhancement such as heat treatment is common from precious gemstones to semi precious gemstones. It remove greenish colour in aquamarine to give remarkable blue in colour. Under the right conditions, impurities elements are release, result in attractive blue hue sapphire from unappealing milky and dull corundum gemstone.
Clarity in gemstone
As we all know, gemstones crystal grow from natural minerals. The crystal structure determines its strength(hardness), colour(intensity). Disturbance during growth which lead to inclusion and distorted internal structure. The commonly term, Feather inclusion, Crystal inclusion, Needle inclusion. At times, such inclusions is a way to trace their country of origin and enhancement evidence. Most importantly, inclusions are birthmarks to identify the natural gemstones from ones that grew in laboratory or man made.
At times inclusion provide a unique appearance which add value in the gem. Certain inclusion can cause phenomenal effects. The unique cat’s eyes chrysoberyl, star sapphire and ruby, would not have appear without inclusions in the gemstones.
Different cut shape in gemstone
Gemstones are identify by their rough shape, each gem has a possible characteristic shape. Depending on their grow condition and environment. It helps to differentiate ruby from spinel rough, tourmaline from red garnet rough. This natural rough shape dictates finished shape of particular gemstone.
Colour gemstone offer different unique cut shapes, and certain shape are exclusively cut for particular gems. We see round in diamonds, emerald cut in emerald. The shape of a rough crystal usually determine the shape and size of the finished gem. Especially for rare and expensive gemstones, the cutter would minimise the wastage in the carat size, producing the largest stone possible.
Quality gemstone in GIOIA
In GIOIA Fine Jewellery, it is our top priority to source for the highest quality gemstone instead of second grade quality to make up for the numbers. As discussed earlier, Colour, Origin, Enhancement, Carat, Clarity, Cut, are the key factors when we acquire quality gemstone. Unlike synthetic or man-made stone, they are natural gemstone mine underground. Almost impossible for us to replace another exactly the same.
Vivid colour and non treated gemstone, might not be in a particular shape. Perfect ideal cut shape and carat size, might not come in flawless clarity. In conclusion, there is always a tradeoff or prioritization in the selection on coloured gemstone.
