Diamonds can also be cut into a wide array of “fantasy” cuts which include the marquise, baguette, heart, teardrop, oval, and princess (a three-sided or four-sided cut with sharp corners which is especially popular for engagement rings).ĬLARITY: Clarity is determined by the number, size, and distribution of any inclusions (internal impurities) in a diamond: The most popular cut is a round one known as the brilliant cut. These four properties then significantly influence the price of a diamond.ĬUT: The right cut gives a diamond its radiant luster. In the process of evaluating and certifying diamonds, they are assessed based on four fundamental parameters which are called the 4Cs: cut, clarity, color, and carat. You should protect the stones from pressure and temperature shocks. With earrings and jewelry which have multiple sapphires, we always state the total number of carats of all the stones.ĬARE : Soak jewelry with sapphires in warm soapy water and clean it with a soft brush.

WEIGHT : The weight of a sapphire is expressed in carats (ct) to 2 decimal places - 1 ct = 0.20 g. However other shapes are also used, such as the oval cut (especially popular in rings and necklaces) or fantasy shapes such as the marquise, heart or teardrop.

ĬUT : Jewelry with sapphires is most often decorated with stones in a round cut. You will therefore also come across sapphires in a range of colors including pink and yellow. They are very durable and retain their beautiful appearance even with minimal care.ĬOLOR : Sapphires are known for their royal blue color, but apart from red rubies, all other corundums are also classified as sapphires. Sapphires are corundums with a hardness of 9, so only diamonds are harder than them. Sapphires are among the most popular gemstones and together with emeralds and rubies, they make up the big three of precious stones.
