Demand for both gem and industrial diamonds is very strong. To fulfill this demand these days Synthetic diamonds are being produced in sufficient amount, this synthetically produced diamonds are being supplied for industrial uses, but these synthetic gems remain inferior and expensive, not suitable for the large jewellery market. The large gem market is still dependent on diamonds supplied by mining.

Demands for Diamond – A Simple Study

Demand for diamond is strong globally. The US$0.7 billion per year market for industrial diamond is now almost exclusively supplied by annual synthetic production of about 1000 million carats. Gem-quality synthetics remain inferior and expensive to produce, so the diamond jewellery trade is supplied by mining of natural diamond, derived from kimberlites, lamproites, and gravels.

Diamond Sales and Uses – A Global Scenario

Recently the world diamond selling market has achieved record sales, especially in the US where half of all gem diamonds are sold. Annual production of natural diamond, at a cost of about US$2 billion, has reached a total of over 110 million carats per year, and this production sells for about US$7 billion, resulting benefit of US$2 billion. Botswana, South Africa and Russia dominate the high quality production mostly handled in Antwerp and Tel Aviv, while Australia and Congo are leading suppliers of the low quality stones that are cut in India. The two-thirds or so of this annual supply of rough that is gem quality is reduced to between 20 and 30 million carats of polished goods and sold in jewellery for about US$55 billion. The one-third of all natural diamonds used for industrial purposes fetches only about 1% of mining revenue.

Diamond Needs in Future

The demand for diamonds is going to increase more in future. Both industrial uses as well as use of diamonds as gems in jewellery products will increase. So there is strong need of discovery of new sources of diamond along with new scientific approach of mining diamonds.

Will rhodium plating to a white gold ring add karats to the gold when tested?

I have a white gold ring, purchased as 18K, and even stamped “18K” but when I took it in to be appraised I was told that the gold tested at 12K. I also know that my ring is in dire need of rhodium plating, which I am having done now. After the rhodium plating, will it be 18K, or was I just scammed and it will always be 12K?

Well, gold is mix of metals, & depending on certain amount from each metal, carat/purity is calculated. For white gold, there r Nickel white golds & Palladium white golds.
Plating is just a finishing step, it’s not gold! If u have a 12K piece, it’ll always stay 12K.
