Depending on the overall quality of the raw stone, about 60% of its carat weight can be lost while the diamond cutter executes the plan for the cut, designed to maximize the stone's clarity and colour.
As a rough stone, there is no fixed price for a diamond, because its clarity, its colour, and its cut are not determined. Take your rough stone to a diamond cutter who can plan a cut for the stone. Once planned -- the cutter will plan a cut to highlight the rough stone's natural colour and clarity -- so that you can have your cut diamond valued. The diamond cutter may purchase the stone from you outright, or make an agreement with you to be paid from the sale of the finished stone.
Faceted diamonds are cut from raw stones by diamond cutters who are trained to plan and execute a cut. The goal is to preserve as much of the natural characteristics of the stone as possible, such as its clarity or colour, with the highest remaining carat weight. (About 60% of the raw stone is lost in the cutting process.)
Raw diamond stones are cut according to an individual plan made for that particular stone, which maximizes its natural clarity and carat weight. (About 60% of the raw stone is lost in cutting into a fine shape.) Diamonds are cut with diamond-tipped tools, lasers and polished using wheels coated in diamond dust.
The cut of a diamond is what gives the mineral contained within the stone its access to reflective and refractive qualities of light. If a diamond is poorly cut, it will not have the 'fire', or dazzle of a well-cut stone.
Diamonds are the hardest natural material, so only another diamond can cut them. Gem cutters use specialised diamond-tipped tools and lasers to shape and polish rough diamonds into gemstones with precise facets. At We Buy Diamond, expert gemologists work with precision cutting and valuation techniques to ensure every diamond or gemstone retains its maximum beauty and value.
The cost of this expertise depends on the raw stone you present, or the instructions you give to a diamond cutter to re-shape the existing cut of a gemstone.
Diamond. Diamond is, for example, polished with diamond powder.
Because diamond is harder than any other stone. In fact, diamonds are cut by other diamonds.
Yes, of course. When the diamond cutter cuts a diamond and removes part of it, reshapes it and otherwise develops the 'cut', nearly 60% of the total raw-stone, carat weight can be lost.
Diamond cutters can help you evaluate the cost and benefit of cutting a polishing a diamond. If you take a raw stone to a diamond cutter, the cutter may collaborate with you as a business partner, to cut and polish the diamond based on the combination of the raw stone that you contribute and the skill the cutter contributes to the venture. Or simply charge you a fee. If you own a stone that you want to re-cut for some reason, you can ask a qualified diamond cutter whom you trust to give you an estimate of the fee and of the value of the resulting, re-cut diamond.
The answer depends on whether you found a raw stone, or a cut diamond. If you found a raw stone, you must consult with your station manager to determine whether it is legal or not for you to remove an(y) artifact from the Antarctic continent. It may not be legal -- it is illegal for anyone working at a US station to take out any artifact that is not directly related to and fully documented as part of a scientific grant. If you found a cut diamond, clearly someone has lost it. Reasonably, you would turn it in to the station's lost and found department. If, over time, the cut stone is not claimed, the department may well give the cut stone to you.
A diamond is valued by its cut, clarity, carat weight and colour. A local jeweler can look at your stone and give you a precise answer.
