Learn About Diamond Grading
Most diamonds of gem quality used in jewelry vary in shade from completely colorless down to a visible tint.
The rarest and most expensive are diamonds in the colorless range graded D,E and F on a scale that descends to Z.
Diamonds with more color than Z, or in other shades such as orange, pink, blue, etc. are classified as "Fancy Colored Diamonds".
Since diamonds form under extreme heat and pressure, internal and external characteristics are common. These characteristics help gemologists identify individual stones.
In order to grade the clarity of a diamond, it is necessary to observe the number and nature of external and internal characteristics of the stone, as well as their size and position.
While probability determined the color and clarity of a diamond, man is responsible for the cut quality which brings it to life.
The planning, proportions, cutting precision and details of finish determine how brilliant, dispersive and scintillating the diamond will be. If the cutting factors under man's control are not optimized, the appearance of the diamond can be adversely affected.

What is the difference between platinum, 18K gold and 925 silver?"18K white gold (AU750) 18K white gold is made up of 75% precious metal "gold" plus 25% other white metals, making it a silver-white combination. It is a common material for high-end jewelry. 18K gold is characterized by its strength and durability, and is suitable for long-term wear. We recommend customers to choose 18K gold. Platinum (PT950) PT950 is composed of 95% precious metal "Platinum" plus 5% other hard metals. The natural silver white color is extremely durable and will not oxidize, making it the most ideal high-grade material. Platinum is heavy and hard. It is suitable for long-term wear. If you perfer PT950 for your jewelry, please contact us. Sterling Silver (S925) S925 sterling silver is a more common silver-white precious metal. Because it is not very hard and can oxidize easily, other white metals is plated on the surface of pure silver to make it harder to oxidize. However, frequent cleaning is still needed to maintain its shine.
