Diamond Bottlenecks 'Signature Series Ultimate' Lead Crystal Slide
'The Ultimate'. A pretty bold name right?! Well it deserves it, these hand-blown lead crystal glass slides are truly stunning, I personally own many of Ian's handmade slides and have used them for well over 10 years now. Totally seamless with perfectly smooth sidewalls, available in a variety of wall thicknesses (4mm up to 7mm) colour options and specifications, these lovely slides great if you struggle to find just the right fit.
These in particular are Signature colours for Ian's collection of great artists he works with. These are essentially the Ultimate model, but in Signature, artist request colours.

About Lead Crystal
Here's a bit of extra info about Lead Crystal slides, which I'm sure will help cement your decision of ordering one:
Hand-Blown Lead Crystal slides are considered by many to offer the sweetest, most 'hi-fi' tonal response of any currently available glass guitar slide for all electric, acoustic & resonator instruments.
Although crystal is the softest glass produced in the glass industry, the pure resonance, weight & density of true lead crystal allows the player a quality & clarity of tone not found with soda-lime (commercial bottling glass) or 'Pyrex' (boro-silicate) slides.....if you tap boro-silicate or soda-lime glass tumblers with a nail, then do the same with a lead crystal glass tumbler of similar size - you'll find the 'ring' & smooth sustain of lead crystal will be sweeter & last far longer.
Durability is applied to lead crystal by 'annealing' the blown glass tube in the 'Lehr' and allowed to slowly cool over several days, providing the required necessary hardness against knocks & string wear.
