Cladding, also called edging, wraps the gem with a metal edge, so that the gem can be sealed in a metal bracket or a metal frame below the waist. The fluidity of precious metals can prevent gems from falling off. It can be divided into edged mosaic and non-edged mosaic. The former is surrounded by metal edges, which is technically called a "stone bowl". The latter is that the metal wrapped around the gem has no annular edge, which is used for the inlay process of small-particle gemstones or accessory gemstones.

2. Tip setting

The so-called pointed inlay is to hold the gem tightly with metal claws, so that the cut surface of the gem looks clearer because it is not covered, and also allows light to enter the gem from different angles and reflect it. Pin setting is divided into six pin setting, four pin setting and three pin setting. This process requires the claws to be uniform in size and spacing, and the table top of the gem is not horizontally inclined. Pointed inlay is usually used to inlay spherical, square, trapezoidal and arbitrary shaped gems and jade.

3. Excellent

Nail setting is the process of directly shoveling several small nails on the edge of metal material with tools to fix gems on these small nails. In this way, you won't see any metal claws fixing the gems on the surface, but the closely arranged gems are still firmly embedded in the metal tenon and groove. Because there is no metal surrounding and shielding, gems can reflect light more.

4. Card Mosaic

Clamping is to fix the waist of a stone or the part between the waist and the bottom tip by using the tension of metal materials. This technology is more advanced than tip setting, and it is the representative technology of pre-fashion technology. It can be given life by designers, and it will change endlessly, because there are more exposed stones, which can better show the cutting and fire color of the stone itself.

Step 5 insert

Mosaic is mainly used for organic gems, such as pearls and amber. In the middle of a dish-shaped metal "bowl", a metal needle extends vertically and is inserted into pearls or amber with small holes to fix the gem. Because the gem has no cover, the shape and light of the gem are displayed in an unobstructed view.
