Lucara Diamond is a prominent mining company that specializes in the exploration and production of high-quality diamonds. Primarily located in Botswana, Lucara operates the Karowe mine, which is renowned for yielding some of the world's largest and most valuable diamonds. The company's main objective is to efficiently extract diamond resources while upholding environmental and community standards. For Muslim investors, though, the most pressing question is simpler: is Lucara Diamond a Halal investment?
Is Lucara Diamond Shariah compliant?
No. In the October 2026 screening Lucara Diamond (LUC) does not pass AAOIFI screening: it fails the interest-bearing investments and interest-bearing debt screens. Extracting and selling oil, gas or materials is a permissible business, so companies like Lucara Diamond rarely stumble on the activity screen. The pressure point is capital structure: energy is a capital hungry industry that borrows heavily, and AAOIFI Shariah Standard No. 21 caps interest bearing debt at 30% of market capitalisation, a line that moves as commodity cycles move the share price.
Does Lucara Diamond pass the business activity test?
The activity screen is only part of the picture this month: Lucara Diamond currently fails the interest-bearing investments and interest-bearing debt screens, so the overall verdict is not compliant regardless of the business itself. The activity itself, extracting and selling resources, raises no Shariah objection; the scrutiny belongs to the financing.
Is Lucara Diamond's income Halal?
Yes, within AAOIFI's tolerance. Lucara Diamond's income from non-permissible sources stays below 5% of revenue in the October 2026 screening.
Does Lucara Diamond meet AAOIFI's debt and investment ratio requirements?
No. Both ratios currently breach the 30% caps, measured against a market capitalisation of CA$246M (market data as of 1 October 2026): interest bearing investments and interest bearing debt each exceed the limit AAOIFI permits for a Halal investment. The ratios move with the share price as well as the balance sheet, and our Shariah Supervisory Board has LUC re-screened every month.
Why do other halal screeners show a different verdict for Lucara Diamond?
Screeners can disagree without either being wrong. AAOIFI Shariah Standard No. 21, which Tabadulat applies, measures interest bearing debt and investments against market capitalisation with a 30% ceiling. MSCI and FTSE measure them against total assets with a 33% ceiling, and S&P and Dow Jones Islamic use a multi year average of market capitalisation. Data dates differ too, because each provider reads filings and prices on its own schedule. The same company can therefore pass one standard and fail another in the same month. Tabadulat publishes one answer, the AAOIFI result as of October 2026, and re-screens it every month.
