1、 Classification of Crystal Lamps
1. Crystal lamp, crystal sand, crystal candle lamp, crystal ceiling lamp, crystal wall lamp, crystal floor lamp, crystal desk lamp
2. Fixed: pendant lights, ceiling lights, wall lights. Mobile: desk lamps, floor lamps

2、 Distinguishing the quality of crystals
1. Touch, high-end crystals have sharp edges, while mid-range crystals have a smooth hand feel;
2. Anti counterfeiting mark;
3. Number: 224 high-end crystal cutting surfaces, 120 Egyptian and domestic ones;
4. Check if the corners are aligned. The cutting surface of the high-end crystal ball is very aligned, but there is a deviation between Egypt and domestic products that cannot be aligned. Looking at the hole position, it is high-end, exquisite, uniform, smooth, and neat. Other brands have uneven sizes and rough surfaces. Whether the transparency and refractive index are strong;
5. Weigh the weight. The lead content in high-end products exceeds 30%, with a heavy feel in high-end products and a light feel in low-end products.

3、 Knowledge of Crystals
1. The main chemical component of crystal is silicon dioxide
2. The refractive index of crystal depends on the content of lead oxide (≤ 33% for Swarovski balls, ≤ 32% for Egyptian balls, ≤ 22%~31% for domestic first grade balls, ≤ 8%~18% for domestic second grade balls). The more lead oxide it contains, the richer its luster and color, and the heavier its weight.
The higher the purity of the crystal, the less bubbles, water ripples, and impurities it contains, and it is crystal clear and transparent, which can better exert the best optical efficiency, allowing the light passing through to refract magnificent colors and a uniform and concentrated color spectrum (rainbow).
4. High quality crystal products will use lead containing crystals, with lead oxide not less than 30%, which is a pure raw material that can emit sparkling and brilliant colors.
5. The world's first crystal glass chandelier was born in the romantic capital of France
Currently, imported crystals are mainly produced in Austria and Egypt. (Currently, the industry distinguishes based on the standard of lead content)
7. The Swarovski brand from Austria is currently the pinnacle of crystal lamp brands, with another brand from Swarovski being Strauss. SPECTR crystal accessories are high-quality products from Swarovski.
Swarovski has been a globally renowned manufacturer of cut crystals since 1895.
9. Crystal origin: 1) Domestic production: mainly concentrated in Zhejiang, while high boron glass tubes are produced in Yancheng and Wuxi, Jiangsu.
10.2) Imports: Egypt, Austria (Swarovski)
Crystals: Swarovski crystals, Egyptian crystals, domestic crystals
11. Classification of crystal shapes: pear shaped pieces, Loong Boat sticks, phoenix tails, maple leaves, crystal balls, octagonal beads, tortoise pieces, diamond shaped pieces, crystal pendants, square beads, pineapple beads, heart shaped pieces, net shaped pieces, pointed beads, arrow shaped pieces, pointed bars, leg, chicken heart, egg shaped pieces, frog pieces.
12. Commonly used crystal balls are 40 # and 30 # balls, commonly used crystal wind blades are 3 inches, 2.5 inches, 2 inches, and 1.5 inches, commonly used crystal octagonal beads are 14 #, and commonly used crystal pineapple beads are 10 # and 8 #.
