When it comes to the secret inlay method which can show the beauty of precious stones without exposing the metal inlay, the first association is the French jewelry brand Van Cleef &; Arpels), since 1933 was patented, this technology is most commonly used in the works of ruby, sapphire and emerald. Gems, such as gorgeous fabrics, are perfectly attached to the surface of jewelry, and the secret lies in the metal mesh below. Keeping pace with the times, the brand has launched a mysterious Vitrail suit that can show transparency in recent years. The secret mosaic method of colored glass and the secret mosaic method of Navette mysterious suit, which create three-dimensional effect, continue to perform mysterious tricks.

The traditional secret inlay technology originated from the secret inlay technology of 1933, which embeds gems in a metal grid less than two tenths of a millimeter thick, so the gems are suspended on the metal and covered on the jewelry surface without external support. According to Van Cleef & Arpels' calculation, it takes at least 300 hours to make a brooch, so the annual output is very scarce. The most representative work is the fairy-shaped Fu D? Ole fairy brooch, Louvre brooch shows vivid petal lines.

The wings of the first work, Libellule dragonfly brooch, show the effect of increasing reflection and relief.

▲ Pomme de pin pinecone brooch inlaid with horse-eye emeralds and diamonds is the first work of Navette Mystery Set secret inlay technology.

After 65,438+00 years' research and production, Van Cleef & Arpels launched the Pomme de pin pine pin brooch in 2065,438+08, using brand-new horse-eye gems. The first challenge is for gemologists to select ***92 crystal emeralds, and the second challenge is to polish them into a micro-arched posture to show the pinecone curve, but emeralds are fragile, which greatly increases the difficulty of inlay. At the same time, we should also consider avoiding the influence of metal claws on diamond clarity. The workshop took 4,500 hours to form a three-dimensional layer like a pine cone with overlapping emeralds and diamonds, which is lifelike.
