How to choose jadeite egg-shaped noodles

Among jade products, plain products are more common, generally there are two types: ring faces and bracelets. Plain jade products have very high requirements for jade raw materials. Here are some common sense in buying jade egg-shaped products.

contour:

The outlines of jade ring faces include egg-shaped (oval), pear-shaped, marquise-shaped, saddle-shaped, heart-shaped, crescent-shaped, rectangular, etc., with egg-shaped being the most common; the outlines of jade bracelets include round rod and flat round rod, among which round rod bracelets are divided into thick rod and thin rod; the rod diameter of thick rod bracelets is generally greater than 10mm, and the rod diameter of thin rod bracelets is generally 10mm or less.

symmetry:

Jadeite emphasizes full shape and neat workmanship. For jadeite ring faces, whether it is egg-shaped, marquise-shaped or other shapes, it is required to have good symmetry. If the bottom surface is uneven or asymmetrical on the left and right, it will reduce its value.

Aspect Ratio:

The appropriate length-to-width ratio creates the beauty of jade's appearance. For example, the length, width and thickness of a plain egg-shaped ring are 20mm*13mm*15mm respectively. If the ring face is biconvex, it can be said to be of appropriate size proportion, or "of good quality."

Thickness and curvature:

For plain egg-shaped jadeite ring faces, the thickness of the ring face and the curvature of the top surface are more important than its outline, because a ring face with a certain thickness and curvature has a better optical effect than a relatively flat and thin ring face. Sometimes, in order to make jade more transparent, the ring face is processed by digging out the bottom, but at the same time it also affects the value of the jade itself due to the reduction in thickness. Generally speaking, ring faces with two convex sides are better, while those with flat bottoms are inferior. The more the bottom is dug and the thinner the ring surface is, the lower the value.

Although the jade ring is just a simple ring of metal and a simple jade egg-shaped surface, it symbolizes beauty and is the best way to express love. It is also a fashion and a widely used decoration in life.

Jade rings come in a wide variety of colors, including green, purple, red, yellow, etc. There are many styles, some with gorgeous inlays, some with tough styles, some with fresh and simple styles, and some with grand and retro styles. No matter from which point of view, jade rings make people feel unique and noble.

In the past, pure gold (24K gold) was used to set jadeite rings. In recent years, 18K gold has gradually been used. 18K gold is harder than 24K gold and can be made into claw-set styles, which allows the jade ring face to be more exposed, making it more solid and increasing the charm of the jade.

Jade ring faces. Since jade is hard jade, it is always cut into a plain surface (also known as a curved surface). Based on the shape of the ring face, the most common ones are egg-shaped (oval), pear-shaped, marquise-shaped, nostalgic-shaped, saddle-shaped, square, and heart-shaped.

The most common shape is the egg-shaped (oval). The carving of many gemstone ring faces has specific size and thickness requirements, but jade ring faces need to be cut according to color, origin, and raw materials. Generally, the major and minor axes of an ellipse differ by 2 mm. The specifications include 8*10, 7*9, 10*12, 20*16, etc. The larger the size, the more valuable it is in geometric progression. The thickness of a jade ring face is very important and will directly affect its value.

A ring face with good color, good quality, double convexity, large thickness and large curvature can increase the crystal clearness and brightness of jadeite, and the color is more pleasing to the eye, so the value of such a ring face is higher. A ring face with a small thickness will leak light, so its value will naturally be lower.

There is a kind of ring face with a hollow bottom on the market now. Most of them are made because the color of the raw material is too dark and the material is very dry, so the method of hollowing the bottom is used to make light easier to pass through, increasing the sense of transparency and making the color look lighter and brighter. This kind of ring face is called thin parallel import. If it is dug too deep, it will be like a domed eggshell. It is a thin layer and is very easy to break due to impact. Therefore, unscrupulous merchants will fill a thick layer of resin underneath to protect it.

Since most jade ring faces are made using a plain cutting process, they must have color, bright and even color, and preferably a certain depth. As the saying goes, "Small pieces require color, large pieces require water", which refers to the picky attitude towards the color of the ring faces. In addition, there must be no major flaws or cracks inside the ring surface.
