bridal jewellery factory How to choose middle and low grade colored gemstones (moyen)

Posté le par Joyjy

The clarity of red tourmaline is mostly poor, and there are often some cracks and inclusions inside. As a ring face rubellite, its clarity is generally good. When consumers buy rubellite, they must first choose the color of peach, the darker the better, the color is too light or brown is not good, and secondly, consider the less cracked package and the fire. Large rubellites, such as finished products weighing more than 3 carats, are much more expensive than small ones around 1 carat. As a pendant, it is a good choice to use large-grain rubellite with a deep pink color.

Ruby garnet is a low-grade gemstone. Not only is it cheap, but its particle size has little effect on the price. Par exemple, the size of red garnets ranging from 4 mm x 6 MM (weighing about 0.6 carats) à 9 mm x 11 MM (weighing about 5 carats) has little difference in price per carat. Donc, it is very cost-effective to buy large red garnets to make jewelry.

The most important quality of red garnet is color. Its colors range from blood red, orange red, dark red to black red. In most cases, the color of red garnet is black, so it can be said that the lighter the color, le meilleur, and the worst blackening. The color of red garnet has a big disadvantage, c'est, no matter what red it is, it has different shades of brown, making the red impure. Donc, the red garnet with the best color has a worse appearance than the low- and middle-grade ruby.

In addition to color, we must pay attention to the fire situation of red garnet. Since garnets have good clarity, the quality of the fire is mainly determined by the depth of cut and color. When the color is light (not black) and the cut is good, the red garnet can reflect a deep red flash. When the color is too dark, the red garnet looks like a black stone, with no red sparkle, and its quality is very low. When the color of red garnet is too dark, you can choose to cut and polish it thinner, the transparency of the thinner is better, you can see that the gem is brownish red.
