Three Diamond Industry Catalysts to Look For in 2020

December 9, 2019By Paul Zimnisky,

Following a strong first-half of 2018, the following 18-months have been disappointing for the diamond industry. The third significant industry lull in the decade-and-a-half since the dismantling of the De Beers monopoly seemingly indicates that the diamond industry is still yet to find sound, sustainable footing in a new era.

A tightening of credit to diamond manufacturers following the mid-2018 surfacing of a widely-publicized, alleged, $2 billion fraud by well-known Indian industry titans Nirav Modi and Mehul Choksi in part led to accelerated industry-wide mid-stream inventory deleveraging throughout 2019. An estimated $10 billion, or approximately 25% of all inventory held by the mid-stream segment of the industry, was forced downstream as many manufacturers were unable to retain previous levels of finance and were pressured to scale down operations and cut-back balance sheets. The flood of excess mid-stream supply more than offset a 5% year-over-year decline in mined diamond volume in 2019.

While the industry has since actively worked through much of the indigestion, demand challenges including a lack of resolution of the 18-month long trade spat between the U.S. and China, directly impacting the industry’s two largest end-consumer markets, has stifled the process. Further, wide-spread protests in Hong Kong, referred to as the Anti-Extradition Law Amendment Bill Movement, have impacted retail sales in the industry-important market and have also interfered with business-to-business industry trade in the second half of 2019. In addition, indications of a broad economic slowdown in Europe and a global trend towards negative interest rates has boosted the U.S. dollar which has pressured global end-consumer diamond demand in recent quarters.

Looking to 2020, if the global economic picture stabilizes, or hopefully even improves --the U.S. would likely need to avert a recession and China would need to maintain at least a mid-single-digit growth rate, the diamond industry could finally be on much more stable footing by mid-year as industry-wide inventories approach much more sustainable levels. At an estimated $30 billion of inventory, mid-stream stocks are currently the lowest since 2011, coincidently the last time diamond manufacturing was notably lucrative.

That said, upstream players, led De Beers and ALROSA (MICEX: ALRS), began building inventory in the second half of 2019 in order to support a balancing of market fundamentals which could limit diamond price upside in 2020.

While macro and micro developments, including some of those mentioned above, will likely continue to impact the market in the coming year, here are three specific catalysts that could have a noticeable impact on the trade as well:

1. The DPA’s “3 Billion Years in the Making” Campaign

In Q4 2019, the Diamond Producers Association (DPA), the diamond industry’s joint category-marketing effort, debuted its latest campaign titled “The Diamond Journey” with the tagline “3 billion years in the making.” 2020 marks the fifth year since the group was established and the third consecutive year that the budget has exceeded an estimated $50 million. The 2020 budget alone is estimated to approach $100 million, which would likely be the highest yet, but is still short of the estimated $200-250 million in inflation-adjusted dollars that De Beers was spending annually during the monopoly-era via the “A Diamond is Forever” campaign.

The result of large category marketing strategies such as this can be slow and gradual in nature but can leave a lasting impact on a consumer’s perception of a product if communicated effectively. It has now been over a decade since the “A Diamond is Forever” campaign was retired and consumers positive perception of diamonds has seemingly faded. However, now a few years into the reintroduction of generic diamond marketing, results should begin to show especially in the three primary markets being targeted: the U.S., China and India.

2. ALROSA’s “Luminous Diamonds” Campaign

In September 2019 ALROSA said it was in talks with several jewelers about joint-marketing the company’s strongest fluorescent diamonds as “Luminous Diamonds.” Fluorescence is most prominent in Russian and Canadian diamonds, which notably tend to be found near the arctic, but fluorescence is also found in stones outside of the far-North and is estimated to be present in as much as a third of all diamonds globally. Diamonds with “strong” fluorescence, the focus of ALROSA’s campaign, represent as much a 5-10% of global supply.

While traditionally fluorescence has been seen as a negative attribute as it can make a diamond appear “milky” or “oily” in direct sun or UV light, the characteristic also makes a diamond mysteriously glow under a black light, ideal for a club or party scene --which fits well with the industry’s intention of directing more marketing towards younger demographics. Further, most natural diamonds fluoresce blue, while most man-made diamonds fluoresce orange, green or blue-green, so fluorescence is potentially another attribute that the natural diamond industry can use to differentiate its product from man-made. ALROSA said it expects the product-line to be available in early-2020 with the U.S. and China being the initial target markets.

3. The Argyle Mine Officially Closing

Easily the industry’s most anticipated supply catalyst, Rio Tinto’s (LSE: RIO) Argyle mine in Australia is finally set to officially close in 2020. In June 2019, management told media outlets that in “late-2020 we’ll be stopping operations and will start the rehabilitation of the site.” The mine, which at one point accounted for almost half of global diamond output in volume, has produced 10-15 million carats in recent years, representing a high-single-digit percentage of the world’s output. An estimated three-quarters of Argyle’s output is brown-in-color, lower-in-quality or smaller-in-size, the categories of diamonds that have been under the most price pressure in recent years.

Argyle supply coming offline will further balance what has been an oversupplied diamond market for most of the last decade. The implication, which will likely be seen as a positive catalyst for the industry, will likely garner a sizable amount of media attention which could boost industry sentiment and reinforce consumer’s perception of natural diamonds --in that they are a fleeting, non-renewable resource, and thus are rare and valuable.
