Buy it.  It is one of the most beautiful lamps I have ever seen.   The glass base is substantial and heavy so it does not tend to tip.   The glass colour is a true amethyst purple (so not a burgundy at all) - but while it is a saturated colour it is not flashy at all.  The colour fades just at the top to clear.  The shade looks like a combination of raw silk and linen - the colour of the shade is a griege - like a grey taupe with a white lining.   It gives the appearance of a really well made, expensive lamp.   We bought 2 for the 2 end tables in our bedroom on the sides of the bed.  The shade allows ample light.
