Good info, especially about all the fake turquoise running around under the names" magnesite and Howlite". Many don't know this.
Could you also do some research on the Gems of Revelation 21 in the Bible and the Exodus gems of the breastplate of the Ephod, in the Bible too.
And your veiw on what those stones actually are in today's terms. To many views, we need to get to the bottom of it. I just found out on YOUR site, that a carbuncle is for sure a " red Garnet" thanks, 'cause there were various ideas about THAT TOO.
My biggest question is.... is a Jacinth and a Hycinth the same stone and are they today's ZIRCON or today's garnet or another stone?
