For those of you who desire a pop of colour in your life, a lab grown coloured gemstone engagement ring could be the perfect option. Today I have Lily Arkwright joining me to help provide you with a simple and comprehensive guide to lab grown coloured gemstones and how to navigate your journey to choosing a lab grown engagement ring!
Did you know that almost any gemstone can be grown within a lab? Chatham gemstones are the architects of the gem growing industry who are known for their superior quality gems by replicating the conditions found deep within the earth’s crust. Chatham are the world leaders of high quality coloured gemstones and have over 75 years experience in producing
lab grown coloured gemstones and they have strict standards for proportions, faceting and polishing that ensure that all gemstones have maximum brilliance, high clarity, and vivid colour. Lab grown coloured gemstones are physically, optically and chemically the same as their mined gemstone counterparts. The only difference between natural gemstones and lab grown gems is that the lab gem growing process occurs above ground, rather than below.
What are the benefits of lab grown gemstones?
An attractive aspect of lab grown coloured gemstones means that the ring can be available in a variety of shapes that are almost impossible to find in naturally mined gemstones. Chatham’s and Lily Arkwright’s production process ensures all gemstones are ethically produced and all gemstones are rich in colour and cut, providing that very special vibrance and sparkle. In gemology diamonds, rubies, emeralds and sapphires are all regarded as precious gemstones. This means that unlike semi-precious gems, precious gems are generally much more desirable due to the intricacies and remote origins of these gems.
The beauty of coloured gemstones are their individuality, colourfulness and romantic meanings. We are regularly seeing celebrities and royals dripping in emeralds, rubies and sapphires on the red carpet but unfortunately these natural gems can be very expensive and rare to come by. When growing gemstones in a lab it cuts out the expensive resources involved in mining, making coloured gemstones an affordable alternative.
The sustainability aspect of lab grown gems is another desirable feature, as no mining is involved thus eliminating impacts on the natural environment, making lab grown coloured gemstones are an amazing sustainable and ethical alternative to naturally mined gems. Let’s break down the top lab grown gemstone types and the meanings behind these vibrant stones.
