(1) purity: clear and transparent, without bubbles, impurities and defects.

(2) Cutting: Different cutting methods have different refraction effects, and the cutting is not good or even dim. The biggest feature of Swarovski crystal is its advanced cutting technology. The more facets a crystal has, the brighter it will be, just like a diamond. In addition, the cutting line is sharp and the cutting surface is smooth without any fine lines. The particle size is absolutely equal, unlike the general crystal cutting line, which has a round feeling and a dull feeling.

(3) Color: A good crystal is pure in color and shows a very obvious rainbow color in light or sunlight.

(4) Translucency: Swarovski crystals have incomparable translucency compared with other ordinary crystals or rock crystals.

(5) The most direct way is to get the swarovski counter for inspection or get the swarovski Shanghai branch.

(6) All Swarovski packages are dark blue, which is the same color as its swan logo. From the outer box to the inner packaging, including brochures, that is, certificates and warranty cards, are all blue.

(7) Open the jewelry box and generally see the certificate first. The size of the certificate varies according to the size of the jewelry. Generally speaking, a square box with a box size of 55mm*55mm is 27 euros. If it is a necklace, it is a long box with a necklace in it. Relatively speaking, his certificate is about the size of a box.

(8) Certificates are generally written in many languages, which are available in most countries. Each language will be signed by Helmut Swarovski, and finally there will be telephone numbers and addresses and e-mail addresses of all offices around the world.

(9) General trinkets are probably afraid of being damaged during transportation. The box will have a sponge pad, and the brooch will have a flannel-wrapped pad. However, the front and back of the necklace are fixed with rubber bands, so there is no gasket, but the box is beautiful.
