Learn about Diamonds that make the planet smile


We created the Diamond Decoder to indicate which diamonds we use at greenKarat and which ones we'd avoid. Learn about lab created, Canadian or conflict free diamonds and natural, recycled or simulant gems. Our goal is to provide you with the info you need to make an informed choice. Use this handy tool to differentiate between stones and learn which you will find in our jewelry.


The diamond decoder uses a thumbs up, thumbs down rating system to indicate environmental friendliness.
