Just some information on how to (not) get ethereal items:
The following cube recipes do NOT retain the ethereal property:
1 Perfect Skull + 1 Rare Item + Stone of Jordan = 1 High Quality New Rare Item of the same type
6 Perfect Skulls + 1 Rare Item = 1 Random Low Quality Rare Item of the same type
4 Health Potions (of any type) + Ruby (any type) + Magical Sword = A Magic Sword of the Leech
3 Perfect Gems (of any type) + 1 Magic Item = 1 New Random Magic Item of the Same Type
3 Standard Gems (normal) and 1 Socketed Weapon (Any Type) = 1 Socketed Magic Weapon (of same type)
3 Chipped Gems + 1 Magic Weapon = Socketed Magic Weapon
3 Flawless Gems + 1 Magic Weapon = Socketed Magic Weapon
The following cube recipes DO retain the ehtereal property:
1 Ral Rune + 1 Amn Rune + 1 Perfect Amethyst + Normal Weapon = Socketed Weapon of same type
1 Ral Rune + 1 Thul Rune + 1 Perfect Sapphire + Normal Helm = Socketed Helm of same type
1 Tal Rune + 1 Amn Rune + 1 Perfect Ruby + Normal Shield = Socketed Shield of same type
1 Ral Rune + 1 Sol Rune + 1 Perfect Emerald + Normal Unique Weapon = Exceptional Version of Weapon
1 Tal Rune + 1 Shael Rune + 1 Perfect Diamond + Normal Unique Armor = Exceptional Version of Armor
1 Lum Rune + 1 Pul Rune + 1 Perfect Emerald + Exceptional Unique Weapon = Elite Version of Weapon
1 Ko Rune + 1 Lem Rune + 1 Perfect Diamond + Exceptional Unique Armor = Elite Version of Armor
1 Ort Rune + 1 Amn Rune + 1 Perfect Sapphire + Normal (Basic) Rare Weapon = Exceptional Rare Weapon
1 Ral Rune + 1 Thul Rune + 1 Perfect Amethyst + Normal (Basic) Rare Armor = Exceptional Rare Armor
1 Fal Rune + 1 Um Rune + 1 Perfect Sapphire + Exceptional Rare Weapon = Elite Rare Weapon
1 Ko Rune + 1 Pul Rune + 1 Perfect Amethyst + Exceptional Rare Armor = Elite Rare Armor
So basically ever recipe that changes the fingerprint removes the ethereal property.
The Charsi imbue, the Anya personalization and the Larzuk socket quest all retain the ethereal property.
