All the gemstones provided by Kalosgem are natural. Blue sapphire and ruby are family members of corundum. Apart from them, there are other family members called “fancy sapphires”, which includes violet, green, yellow, orange, pink, purple, and intermediate hues. However, fancy sapphires usually have less quantity than blue sapphires, and some are extremely rare.

Most of the fancy sapphires are found in Madagascar, Tanzania, Sri Lanka, Myanmar, and Australia.

Due to multiple colours of sapphires, we designed the “Initial rainbow sapphire collection” to show the amazing colour of sapphire. Our “Initial rainbow sapphire collection” contains unique sapphire gemstones with their unique natural colour. The product image on our website shows the basic colour combination, but the colour and sequence of each real product is all unique. So, if you were the girl disliking surprise, be careful to choose this collection.

The “Rainbow Sapphire Collection'' of Kalosgem combines almost all possible colours, which is dedicated for romantic girls who love colourful jewellery. Compared to the common diamond, the initial rainbow sapphire necklace highlights the personality of girls, bringing colourful elements to our life. Meanwhile, it is also one of the best gifts for gemstone lovers and collectors, as one necklace covers most of the possible colours of sapphire.
