I will present new results on the nature and diversity of the most luminous Lyman-alpha emitters at z~7, including some newly discovered ones. We confirm a high, non-evolving number density of these luminous Lyman-alpha emitters into re-ionisation, which may indicate that they reside in early ionised bubbles. Their rest-frame UV spectra shows diverse Lyman-alpha profiles, absence of high ionisation metal lines (which we can easily explain due to the high Lya escape fraction), and a remarkable variety of rest-frame UV luminosities. I will finish with new exciting results from deep follow-up observations of [CII] and dust continuum, which show that these sources are extremely dust-poor, but that deep enough observations of these sources can finally detect and even resolve [CII] clumps within them.
