During ALROSA’s (MICEX: ALRS) Capital Markets Day on March 18, the company said the most frequently asked questions it gets during 1-on-1 meetings with investors are those related to the impact that synthetic or lab-created diamonds will have on the business.

Three days later, on a Mountain Province Diamonds (TSX: MPVD) analyst call following the company’s full year 2018 results, a portfolio manager bluntly stated, “while I appreciate the attempts to kind of dance around the issue of lab-grown diamonds … I think we all have to just accept the fact that technological improvements will continue, technological progress moves forward and lab-grown diamonds will continue to be a much larger factor.” He added an anecdote, “for those of us who have millennial children, they couldn’t care less whether it’s lab-grown or natural … if it sparkles, looks good and is a diamond, I think that’s what people are going to focus on.”

For any investor that has had exposure to the diamond space in recent years, diamond mining stocks have felt like a vortex that takes your money and does not give it back.

However, it appears that sentiment has now reached a level implying that the independent diamond mining industry will not survive, which is seemingly a stretch too far.

Yes, lab-created diamonds will inevitably take some market share from natural diamonds, especially at the lower price points, just as moissanite and cubic zirconia did. However the extent of this growing market share is yet to be determined and will most likely depend on the success of marketing by not just the lab-created industry, but also the natural industry, which has a very resilient history.

Historically, natural diamonds have been the envy of the luxury industry: the penetration of diamonds is unmatched, it is the one luxury item that most women (American, at least) will be gifted in their lifetime.
However, maintaining such an overwhelming market position is almost as difficult as building it, especially in the post-De Beers monopoly era with the absence of “A Diamond is Forever” campaign. (De Beers is currently 85%-owned by global diversified mining company Anglo American (LON: AAL) and 15% by the Government of Botswana. Most of the company’s subsidiaries are joint ventures with government partners.)

While the challenge of maintaining market penetration in the industry’s most developed markets is offset by new growth in emerging markets, a couple of which (i.e. India and China) have the potential to eventually overtake the U.S. in size, the diamond industry undeniably faces the aforementioned confrontation. Nonetheless, the natural diamond industry seems far from going away any time soon.

Natural diamond supply is estimated to come off this year and continue to incrementally decline through at least 2021, which should be supportive of diamond prices and thus diamond miners.

Weaker diamond prices over the last five-plus years have led to a natural paring of supply which is approaching more normalized levels after reaching a post-global-financial-crisis high in 2017. Also worthy of note, a significant amount of a multi-year inventory-deleveraging in the Indian midstream sector has already taken place and inventories there are also approaching a more normal level.

In addition, despite various global macro-economic concerns, global demand for natural diamonds appears to be relatively stable at the moment. The largest jeweller in the world, Tiffany & Co. (NYSE: TIF), has guided sales increasing at a “low-single-digit percentage” in the 12 months ending Jan. 31, 2020. Importantly, Tiffany does not offer lab-created diamonds. Further, the largest jeweler in Greater China, Chow Tai Fook (HK: 1929), opened a record number of new stores in the most recent fiscal year ended March 31, 2018, an undeniable show of confidence in the growth potential of that market. Chow Tai Fook does not offer lab-created diamonds either.

While investor sentiment is what drives equity valuations — reflected by the “P” of the Price-to-Earnings (P/E) ratio — the “E” is the portion of the equation ultimately driven by price fundamentals and operations which the industry has control over.

Seemingly stable global demand for natural diamonds and an apparent favourable supply picture should be supportive of diamond prices and the companies producing them, especially those with de-risked mining operations and a manageable debt load.
