value of a diamondjewelry appraiser worth his weight in diamonds
Just a few important determinations are taken into account when determining the value of this precious stone. The overriding keystone applied to the evaluation of a gem appears to remain its rarity. All gemologists concur that no two diamonds will be the same. When determining the value of a diamond, this rarity is measured by utilizing the characteristic four Cs, known as Color, clarity, cut and carat weight. But when measuring the color of a diamond, the Gemological Institute of America takes into account its D, going right through a Z. the D defines a colorless diamond while a rock color-coded with a Z is usually light yellow or brown in color. Now, any jewelry appraiser worth his weight in diamonds will tell you that it remains extremely rare to find a truly colorless diamond. But the majority of diamonds evaluated are at least nearly colorless. They all retain tints of brown, gray or yellow. All color grades are determined by measuring diamonds against a master piece if you will. A GIA clarity scale contains eleven grades. These grades range from flawless to the number thirteen. Due to the fact that diamonds form under extreme heat and pressure, it remains rare to locate a diamond that lacks all the internal characteristics known as inclusions and external blemishes. As far as a diamond goes, beauty can never be in the eye of the beholder. Hold one up and you will see. A diamond is always beautiful. The beauty has something to do with the precious stones complex relationship with light. Look at it this way. Light strikes its surface. Light penetrates the surface of the diamond. And it gets reflected out to the beholder in a completely new and different shape and color. Three characteristic attributes are sought out by evaluators in this process of light transference. These are; brightness, fire and scintillation. Brightness combines all white light that reflects from the surface and interior of the stone. Fire is the process of light being scattered into its color spectrum, like the colors of the rainbow. Those flashes of light you sometimes see when a finger ornamented with a diamond gestures in your direction? That's scintillation. Polished diamonds' proportions affect its light performance. This could have a negative effect on the value of the stone. Uncut diamonds perhaps offer the best prospects for collectors where value is concerned. One of the world's legendary diamond prospectors, still a going concern today, once coined the phrase that diamonds are forever. It does appear to be the case because the value of diamonds as a commodity remains quite high. Apart from being cherished as a portion of jewelry decoration, with diamonds being waxed as a girl's best friend, diamonds remain in high demand on the industrial shop floor. A diamond's value is specifically measured in carats with one carat being worth two hundred milligrams of a gram in weight, of the diamond. You see.
