Caster's Realm has some comments indicating that enchanting mithril did indeed require Blue Diamonds. The linked page is a screen shot post-patch, but the comments come months before hand and show evidence that Blue Diamonds were required:

FORGET THIS SPELL, By Bowynn (3/7/2001)

With the implementation of blue diamond jewelry this spell is effectively worthless. Not only is Blue Diamond jewelry implemented, but each metal makes a DIFFERENT piec of jewelry meaning a person can basically wear EIGHT pieces of blue diamond jewelry, Head, 2 earrings, 2 bracers, 2 rings, and a necklace.

DISAPPEARING DIAMOND, By Rhiannan crystalweave (1/28/2001)

Someone asked earlier if the diamond is just needed as a component to cast the spell or if it's consumed? It's consumed! I was called upon to cast this spell and the diamond said, 'Buh-bye'. As far as where you buy the spell, it's sold in the Felwithe casters guild by the vendor who sells the tiny daggers if memory serves me correctly. I bought all 4 of the new enchant spells and all were sold by vendors you wouldn't expect.

DISGRUNTLED ENCHANTER, By Bette (1/28/2001)

The fact that these diamonds usually sell for around 250, and 3 bricks are required for an enchanted elvish chain tunic. In addition to the difficulty in requiring a temper. Wouldn't one say 4int 4wis 2sv mag is kinda shabby for the amount of time and PP put into the armour enchanted mithril can make? My guild has been working on suiting our elvish officers in these tunics. Being that we're a low-mid level guild a 4int 4wis tunic is a very nice peice, but at the level that it's accessible its both useless and extremely expensive, which makes selling it a prohibative trade at best.

54TH ENCHANTER, By Yazz of prexus (1/28/2001)

Memmed this, casted it and we now know you need 2 items.
1.)A large brick of Mithril 2.) A blue diamond.

As for where this drops, I have no idea.

Enchanted Admantite same thing:

SPELL COMMENTS
WAY TOO EXPENSIVE REAGENT, By Shaniallon of mithaniel marr (3/12/2001)

I feel this reagent is way too expensive after the new jewlery came..
Blue diamonds are like 2k now, so a tunic of imbued adamantite would be 6k per attempt, is this really the meaning? SMR is like 5k now, and is a better deal for a caster.
