Each necklace in our Birthstone Collection is made with high-quality in mind, with a price point you can't ignore. First, the stones we use are beautifully made into a rectangular shape, which is called emerald cut in the jewel world. This cut includes stepped facets, which allow the beauty of the gem to sparkle from all angles. Each stone is imported from a small business located in the gemstone capital of the world, Jaipur, India. These are made in small batches, so every necklace is very special. As for the chain necklace findings, we use 100% Gold Filled materials. This means they will avoid tarnishing and will last a very long time.
