Rough Diamond Jewelry

products

Diamonds are famous for the brilliant sparkle that is uncovered when they are well cut. Of course color, clarity and carat are also quite important when determining the value of these precious gems. But if you have looked at diamond settings in the last few years you may be noticing something unexpected, rough diamonds set into jewelry. These diamonds aren’t cut or polished, they are used in their natural state which has quite a different look than we are accustom to seeing.

The Attraction

Since ancient times rough or uncut diamonds have been prized for their beauty and not just by the masses but by kings and queens as well. Jewelry designers of today are appreciating them for their elemental, raw look and setting new trends with this earthy look that isn’t so new.

Some jewelers are creating designs with just the rough diamonds set into precious metals while others are mixing the rough versions with cut and polished diamonds to create a look of rustic elegance. Some designs have a feel of mixing the past with the present, as you can almost feel the ancient roots of the uncut diamonds mixed with the newer diamonds cut with great precision using modern tools.

How Are They Valued?

When it comes to grading and valuing cut diamonds the famous 4 Cs are used: carat, color, clarity and cut. In this case there is a well-defined scale and a GIA certification to verify the value of your jewelry. But when it comes to rough diamonds these same rules don’t really apply.

When it comes to carat weight rough diamonds are always a higher weight than those that are cut because in the process of cutting often times 50% of the original weight is lost to get the best gem or gems.

Cut stones are more valuable when they are as close to colorless as possible, unless of course you are talking about an intense natural color diamond. With the rough or uncut version you won’t find a colorless stone because the outer layer has a frosty look to it. They often come in shades of white, brown, yellow, pink or blue.

The clarity of a stone cannot really be determined until the diamond is cut and polished. Since diamonds in the rough aren’t cut and polished the clarity cannot be determined in the same way it can for a traditional diamond. Of course the same goes for cut.

While some jewelers are trained in judging the quality of a rough diamond there is no standard grading scale or GIA certification for these natural beauties. For most people who buy these beauty is in the eye of the beholder because they are generally valued below that of a cut diamond. Much of their appeal is from the craftsmanship of the jewelry and their unique, raw beauty.

How to calculate a volume of two products, if, if benefits are equal to be obtained from the two?

How to calculate a certain volume of two products (with different selling prices, fixed costs and variable costs), if the gains to be won as both the products? Example – Product X is sold $ 100 each, and sells for $ 120 each. Product X fixed cost $ 20,000 per year and the variable cost of $ 12 per unit, while the product and fixed cost of $ 8000 and the variable cost of $ 40 per unit. What kind of production (volume) are the benefits of both products the same?

X = 1500 units and profits of U.S. $ 88 = gain of $ 80 x 227.27 units required to break even@227.27 units, revenue and $ 10,182 from profit for x> y, $ 8, X "capture" and 1273 units. (228 = unit of equilibrium point for x) + (1273 x = units to "catch" y) = 1500 You can do the double check in itself:)
