What is a variegated stone?
Chrysanthemum stone is a rare ivory gem with the trade name Calcentin or Korit, and its composition comes from the fossil remains of chrysanthemum stone. The Mohs hardness of variegated stones is only 4.8, and the surface color layer is soft and brittle. The closer to the ground, the darker the color of variegated stones, mostly dark red or brown. Because it was oxidized by air. Mottled stones cannot be directly exposed to the air, and the unearthed raw materials will gradually dim within one year without any treatment. Only film mulching can protect variegated stones from oxidative damage.
At present, there are two ways to deal with the mottled color on the market: one is that the original stone drips into crystal glue. Unearthed stones will grind off the colorless parts and directly drip glue. This processing method keeps the unearthed state, and most of them have different shapes. And there are many bumps. The loss of raw materials is small. The disadvantage of this treatment method is that the surface is not scratch-resistant because it is a rubber surface. The other method is to cover the crystal surface, and there is a layer of crystal or sharp crystal on the spot color surface, but this processing method requires the spot color to be flat, the process is complicated and the loss is large. So only small crystal patches can be seen on the market. The first thing to confirm when choosing spot color is whether the surface is covered with plastic film. Because of the high cost of plastic film, many unscrupulous merchants directly sell spot colors without plastic film under the banner of pure nature, and ultimately the buyers suffer.

Pure natural, coated and laminated stones are different, and the prices are arranged from high to low. Fragile texture needs the protection of crystal film to avoid being hurt. Small colored stones, usually with regular shapes, are wrapped in plastic film and used for inlaying. There are few natural stains that can be seen in the market, which are generally irregular blocks and expensive.
