Well after a protracted development (drawing) time I've got around to finishing the millionth iteration of the Gemstone, this time actually with some thought put into it.
Abstract:
Stemming from the CNGF project the Gemstone class of destroyers as one can probably tell ended up being full on destroyers in both displacement and capability terms leading to another design to replace aging frigates. Like the UK Atlantia decided to leave the partnership that would end up with the Horizon class to develop what they had already developed. The result was a family of destroyers outwardly similar in appearance to the Horizon class albeit being slightly larger in all respects.
Unlike the Horizon class the Gemstones were designed to make use of the COGES style of propulsion rather than CODOG. During development there was talk of retaining the proven American VLS rather than SYLVER, politics however decided that SYLVER would be installed to promote European trade and relations (that said IRL SYLVER is to undergo integration of Mk41 capable munitions).
Future:
There are currently 34 Gemstones in service with the Altantian Navy, their future is pretty much guaranteed for several decades current pipepline upgrades include operational integration of UAV/UCAVs, integration of NSM to replace Sea Eagle, Updating of ASTER, operational clearance of CAMM and possible integration of Mk41 munitions.

I think that I can possibly finally lay the Gemstone to rest at last.
