Process of Casting silver Jewellery
A two-step process, investment casting, produces small, complex shapes. Most castings, especially large ones, are made in sand molds. Permanent metal molds are used to make many small, simple parts; shell molding gives greater accuracy for a large volume of semi precision parts.
Molten silver is poured into the cavity and allowed to solidify. Sand, mixed with a binder to hold it together, is pressed around a wooden pattern that leaves a cavity in the sand. Wax or plastic replicas of the parts are molded in accurate metal molds. Top of the line casting equipments are utilized to produce the silver jewellery. When the whole mold is heated, the replica melts, leaving behind a cavity into which silver is poured.
Diamond's clarity is graded
Diamonds with Slightly Included and better grading are progressively more expensive. These include; internal graining, cleavage, bearding, cavities, crystals or minerals, knots, feathers and clouds. After that, we go to the various grades of included diamonds. There are two types of flaws: an inclusion and a blemish. A blemish is something that mars the surface and distracts from diamond clarity.
This includes chips, pits, nicks, scratches, naturals, grain boundaries, and polish lines. The Internally Flawless diamond cannot have any inclusion, but may have surface blemishes. The diamond is then graded on the basis of five considerations: color, nature, position, size, and number. The clarity of the diamond is one of the primary determinants of price when it comes to rings, earrings, and other jewelry. This article will focus on how a diamond's clarity is graded.
