Hidden Camera Video Reveals Just How High Diamond Markups Can Be
06 april 2017
(yahoo.com) - If you’ve ever suspected that the price markups on jewelry, diamonds in particular, was pretty high, a new undercover project reveals just how extreme it really is. Jacob Worth took a hidden camera inside some of New York City’s most luxurious diamond retailers, including Tiffany, Cartier, Harry Winston, and Van Cleef. According to the footage Worth captured, many jewelers are selling diamonds virtually identical to each other, under markups well beyond the average for retail. With his investigative work, Worth determined which of the luxury brands charges the most for the same stones.
Dreadful Wednesdays
06 april 2017
(polishedprices.com) - At prep school, I recall most of my friends finding Monday the worst day of the week, that was probably not because of double Latin classes in the afternoon but simply the idea of the start of another long week. My view was rather different, thank heavens the weekend was over and another day was ticked off. Weekends in a boarding school that long ago were very long repetitive events. My worst day was Wednesday, half way to another weekend. Well, all has changed for me. Gem announced their results this Wednesday, and what absolutely gloriously awful reading they made.
Is the Kimberley Process B.S.?
05 april 2017
(jckonline.com) - Last week, Martin Rapaport, at the International Diamond Conference—Mines to Market, held in Mumbai, India, called the Kimberley Process a word that we don’t use in a family publication like JCK (but you can guess). Vinod Kuriyan wrote a reaction here, which I recommend. Below, Brad Brooks-Rubin of the Enough Project writes in with another, very different take. Brooks-Rubin has also worked as State Department special advisor on conflict diamonds as well as director of global development and beneficiation at the GIA.
From Tulips to Diamonds – Wealth Preservation Asset Needs
05 april 2017
(ehudlaniado.com) - In the past few weeks, we have been talking a lot about the fundamentals of diamonds as a potential wealth preservation asset, and about what it would take to form such a market. This week, I want to touch on the why, specifically from the perspective of buyers. The diamond market I’m envisioning, a spot market for polished diamonds, does not exist in a vacuum. To be viable it must satisfy a need, otherwise buyers, traders, financial firms, banks, and private individuals won’t buy diamonds as a wealth preservation asset. These needs must be met because we are not simply looking to generate a sale. We want to discover, create, arouse, and satisfy customer needs. There are three main needs that can and should be addressed.
Banks Snubbing Belgian Diamond Trade: AWDC
04 april 2017
(diamonds.net) - Belgian banks are discriminating against the diamond trade by not lending to anyone linked to the industry, the Antwerp World Diamond Centre (AWDC) has claimed. The AWDC has proof that banks are systematically refusing customers with any connection to the trade, for both personal and professional banking affairs, it said last week. Lenders snub diamantaires even before they've had a chance to submit a formal application to become a client, the trade body alleged. The banks’ rationale is that the diamond trade carries a high risk, the AWDC said. But it argued that this was an unfair perception, given how much regulation companies must undergo and the degree to which domestic and international organizations monitor diamond transactions.
