The unusual case of a jewel with a large number of flux-grown synthetic rubies sold as natural rubies.

Quote:

A necklace with rather important sizeable rubies was submitted to GGTL Laboratories Liechtenstein with the request to identify treatments and country of origin. The piece was mounted with ≈ 50 stones of high quality and very attractive and saturated red colour; the stones were somewhat included and showed mainly fingerprints and clouds amongst other small and atypical inclusions (Fig 1).
