How reviews and confirmations work

We ask contributors to share a photo they took and their own experience. Reviews go through automated checks. Flagged reviews can be assessed manually. Approval is not a guarantee that a photo is unedited or free of AI generation.

  • Email address confirmed means the link sent to that address was used. It does not prove a purchase or the identity of a person.
  • Company management confirmed relates to access to this company page. A paid plan does not verify individual reviews.
  • A review invitation does not independently prove a purchase. An order reference supplied by a company is not independent purchase verification either.
  • Publishing a photo with a review does not automatically permit reuse in marketing. A subscription does not grant that permission either.

Modern Gem Co positions itself in the accessible premium segment of the jewellery market, with a focus on lab-grown stones as an alternative to mined diamonds. The collections are structured around named lines, such as Remi and Etana, suggesting a design-led approach rather than a purely functional one. Prices range from around £139 for rings to over £500 for necklaces, placing the brand in the mid-to-upper price range for lab-grown jewellery. The shop appears to target consumers who want the look and feel of classic fine jewellery without the ethical or financial cost associated with traditionally mined stones.
