From Mr Garrick Ollivander's notes
Wood: "This unusual and highly attractive wand wood was greatly in vogue in the nineteenth century. Demand outstripped supply, and unscrupulous wandmakers dyed substandard woods in an effort to fool purchasers into believing that they had purchased silver lime. The reasons for these wands’ desirability lay not only in their unusually handsome appearance, but also because they had a reputation for performing best for Seers and those skilled in Legilimency, mysterious arts both, which consequently gave the possessor of a silver lime wand considerable status. When demand was at its height, wandmaker Arturo Cephalopos claimed that the association between silver lime and clairvoyance was ‘a falsehood circulated by merchants like Gerbold Ollivander (my own grandfather), who have overstocked their workshops with silver lime and hope to shift their surplus.’ But Cephalopos was a slipshod wandmaker and an ignoramus, and nobody, Seer or not, was surprised when he went out of business."
Core: "As a rule, dragon heartstrings produce wands with the most power, and which are capable of the most flamboyant spells. Dragon wands tend to learn more quickly than other types. While they can change allegiance if won from their original master, they always bond strongly with the current owner. The dragon wand tends to be easiest to turn to the Dark Arts, though it will not incline that way of its own accord. It is also the most prone of the three cores to accidents, being somewhat temperamental."
Lengths: "Many wandmakers simply match the wand length to the size of the witch or wizard who will use it, but this is a crude measure, and fails to take into account many other, important considerations. In my experience, longer wands might suit taller wizards, but they tend to be drawn to bigger personalities, and those of a more spacious and dramatic style of magic. Neater wands favour more elegant and refined spell-casting. However, no single aspect of wand composition should be considered in isolation of all the others, and the type of wood, the core and the flexibility may either counterbalance or enhance the attributes of the wand’s length."
