Understanding diamonds
At Sirius Jewellery, we use diamonds as side gems. It’s our belief that even smaller gems need to be of impeccable quality to perfectly match the central gem on a ring. We use natural diamonds with a hardness guarantee of least ten. This means that you can rely on your side gems to retain their brilliance indefinitely.

Diamond Cut
Diamond Clarity
Diamonds with fewer inclusions are more valuable. All diamonds contain inclusions which are formed during the creation process. Diamonds are naturally created by a combination of tremendous pressure and heat deep within the surface of the earth. However, gemstones with fewer inclusions are deemed to be of higher clarity. The clarity scale ranges from FL (flawless) to I, which signals that a diamond contains significant inclusions.
Diamond Carat
Carat refers to the weight of the diamond and not its actual size. 1ct is the equivalent to 0.2 grams. Amora gems are typically around 8 percent lighter than natural diamonds, and we provide actual and diamond weights on our certificates.
