Treated vs Non Treated: A Guide For The Gemstone Buyer
READ TIME: 3-4 MINS
WHAT DOES IT MEAN WHEN A GEMSTONE IS REFERRED TO AS "TREATED" OR "NON-TREATED"?
There are a few different treatments that may be applied depending on the type of gemstone i.e Sapphire or Emerald, but one of the most common processes is referred to as heat treatment. This involves subjecting the stone to high temperatures in a controlled environment, mimicking and intensifying the natural reaction that would occur in the earth from thousands of years ago.
It works to achieve a more intense colour of a gemstone without adding any outside chemicals or additional elements. The process of heat treating a gem can enhance the colour or clarity, reduce inclusions or imperfections, and overall improve the appearance of the stone. The temperature and duration of the heat treatment will depend on the type of gemstone and the desired outcome of the gem owner.
WHAT ABOUT NON-TREATED STONES?
Non-treated stones are just that- their natural colour has not been enhanced through treatments in any way. Non-treated stones at top qualities are considered to be extremely rare and are often purchased as a sought-after collectible piece. Although they may carry visible inclusions, these can add to their beauty and uniqueness depending on the desired characteristics from the buyer.
TREATING PRECIOUS GEMSTONES IS AN ART FORM
When treated properly, heated gemstones can radiate an intense and highly saturated colour- it’s a process of enhancement and a true art form in itself. Ensuring the integrity of the stone is kept intact, calculating and regulating the temperatures and environments to which the process is performed is challenging and requires a unique set of skills. Cavalier has maintained relationships with exceptionally talented trades in this field all around the world, and we’re proud of it.
CAN YOU TELL THE DIFFERENCE BETWEEN A TREATED AND NON-TREATED GEMSTONE?
A vast majority of quality gemstones on the market that are vibrant in colour have experienced treatments- it’s a way for buyers to attain incredible pieces in the qualities they are looking for. With that said, the distinction of the process is unmarked and is difficult to detect without the stones traceability documents. Untreated gemstones like Sapphire, Emerald and Ruby, at top shelf colours, qualities and cuts will command an above premium price. So, if the price for a gem is significantly different (at first glance) from a similar counterpart, there may be a reason for it.
