How do you choose jade, and what are the best methods for buying it? What should you pay attention to when purchasing jade in daily life? Here are some key factors that will help you understand and appreciate jade better.
1. Color
Color is one of the most important aspects when evaluating jade. The ideal color should be "positive," "intense," "bright," and "uniform." Even colorless jade has variations in tone, depth, and clarity. When choosing colorless jade, try to go for brighter pieces if other conditions are similar. For floating flowers or oily jadeite, you can also use similar principles to assess their quality.
2. Water (Transparency)
"Water" refers to the transparency of the jade. The higher the transparency, the better. Common terms like "glass type," "ice type," and "scorpion type" are used to describe different levels of water. There are two common ways to rate water:
- Transparent, semi-transparent, translucent, slightly transparent, and opaque — which correspond roughly to glass, ice, alfalfa, bean, and stone.
- Three-point water, two-point water, and one-point water — similar to glass, ice, and ice-like clarity.
3. Structure (Species)
This refers to the texture of the jadeite, specifically the size and arrangement of its crystals. It’s different from terms like “glass,†“golden seed,†or “oil green,†which refer to specific visual effects rather than the actual structure.
4. Blemishes (Flaws)
Jade often contains imperfections such as cotton, dirt spots, or cracks. These can affect the value:
- Cotton: Fine specks or larger clusters of white particles.
- Dirt: Yellow, brown, or black spots or patches.
- Cracks: Straight, deep, and sometimes visible on the surface.
The impact of these flaws depends on their type, size, number, and location. Small, subtle imperfections have minimal effect, while major cracks can significantly reduce the value.
5. Weight (Size)
Weight is an important factor in determining the price of jade. For example:
- A high-quality ice-type pendant measuring 43/28/7 mm weighs around 20 grams and could cost about $10,000.
- If the same quality jade is smaller, say 35/20/6 mm, it might weigh 10 grams and cost around $3,000–$4,000.
- A 5-gram piece may only cost around $1,000, and even smaller pieces can range from $300 to $1,000.
- Larger pieces, such as 40 grams, can exceed $30,000 depending on quality.
6. Craftsmanship
Craftsmanship includes proportion, polishing, and design. A well-made jade piece should have accurate shapes, smooth lines, and a polished finish. Good design makes full use of the material’s characteristics, creating something both beautiful and unique. Poor craftsmanship may result in uneven shapes, rough edges, or unbalanced proportions.
For everyday jade purchases, the first five factors (color, water, structure, blemishes, and weight) are usually sufficient. However, for high-end or collectible jade, craftsmanship becomes just as important as the material itself.
When buying jade or jade jewelry, always purchase from a reputable store or mall. Make sure to ask for a certified appraisal from a recognized quality inspection authority, such as the National Jewelry Quality Supervision and Inspection Center or local jewelry testing institutions. This ensures authenticity and helps protect your investment.
