Diamond open access
Diamond open access is sometimes used to describe gold open access where publication is made freely available on the publisher platform and there is no fee to the author or their research organisation. It is typically used by publishers who are keen to emphasise that they do not charge authors to publish open access (also known as platinum open access).
