You can always give first preference to your jeweler i.e., the person from whom you bought it. You can sell your diamond jewelry to him under a diamond price quote system. Fix a price below which you do not wish to sell your jewelry. You should provide as much information about your diamond as you can. Then, he will verify whether the product was actually bought from his shop or not. For that he will ask for the diamond's certificate. A diamond certificate is the diamond grading report. It is the proof of the diamond's authenticity, identity and value. The certificate gives you the information about the exact size, weight, cut and the quality of the diamond. Once the verification of your item is done, he will offer you a blind estimate. You might expect the jeweler to pay the nearest amount of your purchase value, but, it is not possible in every case as the value of your diamond will depend on the current market status and the condition of your jewelry. With the confirmation of the authenticity of the diamond and your acceptance of the blind estimate, the jeweler presents the firm cash offer to you.
The Darya-I-Nur diamond is thought to be the largest, and one of the oldest pink diamond in the world, with an estimated weight of somewhere between 175 and 195 carat. It is light pink in colour and has been mounted in its present brooch setting for more than a 130 years, making it difficult to determine its precise weight. This diamond is housed within the Iranian Crown Jewels, and is eminent among a collection of rare and beautiful gemstones. The Steinmetz Pink Diamond is another renowned gem, classified as a vivid pink and weighing 59.60 carat. This stone, the largest fancy vivid pink diamond in the world was discovered in South Africa. The Steinmetz diamond took a team of eight specialist jewellers 20 months to create the flawless masterpiece that exists today. This dazzling gem among gems was finally unveiled to the world during a public ceremony held in Monaco in May 2003.
It takes millions and millions of years for diamonds to form in the Earth's mantle. For this to happen, the temperature must be around 2000 degree Fahrenheit and the pressure must be 45 and 60 kilobars. Such favorable conditions exist only in some limited regions of the Earth's mantle. Variations in temperature and pressure may affect the formation of diamonds. A dip in the pressure or a rise in the temperature may result in dissolution of the diamonds or partially formed ones.
