336 results about "Gemstone" patented technology

A gemstone (also called a gem, fine gem, jewel, precious stone, or semi-precious stone) is a piece of mineral crystal which, in cut and polished form, is used to make jewelry or other adornments. However, certain rocks (such as lapis lazuli and opal) and occasionally organic materials that are not minerals (such as amber, jet, and pearl) are also used for jewelry and are therefore often considered to be gemstones as well. Most gemstones are hard, but some soft minerals are used in jewelry because of their luster or other physical properties that have aesthetic value. Rarity is another characteristic that lends value to a gemstone.

Defect traceability analysis method for jewelry multi-surface treatment process

The invention belongs to the technical field of image processing, and relates to a defect traceability analysis method of a jewelry multiple surface treatment process, which comprises the following steps: injecting three marking substances corresponding to light with different wavelengths into surface positions with different depths to form a marking layer which can be identified by subsequent detection equipment; generating processing record data of the current process; collecting a pressure change waveform applied to the gemstone in the machining process, and generating a mechanical feature vector in combination with working parameters of equipment; inputting the processing record data and the mechanical feature vector into a preset process knowledge base to identify an abnormal parameter coupling relationship, and generating defect reason positioning information; comparing the deviation values of the actual parameters and the digital twinborn standard parameters layer by layer to generate a visual deviation report; generating a machine executable process optimization instruction; and updating through a transfer learning algorithm to form a self-evolution quality control link. The problem that a complete evidence chain from stress fluctuation to surface flaws cannot be constructed due to separation of a marking method and a detection technology is solved.
