Quezal quality control was better than Tiffany's.  It's rare to find a poor quality Quezal vase.  This example is stupendous, with vivid green pulled feather decoration and gold iridescent border on an opal ground.  Additionally, it has double the standard decoration, with an upper and lower decoration.  The entire underside is decorated (for those who like to display their glass upside-down :>)  The interior has stretch glass with strong orange-gold iridescence.  Good size at 4" t. x 8¼" diam.  Beautifully engraved Quezal signature on the underside.  Mint condition.

The most common decoration on Quezal vases and shades is pulled feather. This beautiful coupe has rare and desirable leaf decoration with random threading. Add a rare shape and you've got a winner. 5½" tall x 6" diameter. Early engraved signature on the underside. Mint condition.

What this Quezal vase lacks in size, it makes up for in quality.  The color and decoration are superb.  In addition to the busy green decoration, there is a gold pulled feather overlay decoration on both the foot and below the rim.  The interior has a rich reddish-gold iridescence.  In addition to the beautiful Quezal signature and number is a museum number, indicating it was de-acquisitioned.  4¾" tall x 4" diameter at the widest.  Mint condition.

Beautiful, busy, random vine decoration on this lovely footed vase, 6" tall x 4¾" diameter.  Signed.  Mint condition.

Quezal often did pulled feather decorations, but rarely did fishnet decoration on vases.  In addition, the foot has a gold iridescent zipper decoration.  This floriform compote is one of the nicest I've ever had the pleasure of owning.  Nice size at 4¾" tall x 5¾" diameter, so it appears large.  Beautiful stretch glass gold iridescent interior.  Signed.  Mint condition.

Quezal vases are consistently high in quality and this example is no exception.  The beautiful pulled feather decoration is overlaid with a gold iridescent pulled feather on the foot.  The stretch glass interior has magnificent rainbow iridescence with beautiful swirls.  This is a top-notch vase, signed and numbered.  6¾" tall.  Mint condition.

Careful workmanship is the hallmark of Quezal.  This example is no exception, with the added detail of a gold iridescent border on the pulled feather decoration.  6¼" tall.  Signed.  Mint condition.

Another superb example of Quezal green pulled feather decoration.   Gold iridescent, stretch glass interior.  Signed.  5½" tall.  Mint condition.

Beautiful random gold threaded decoration, marvered flat, on an opal ground.  The rim with gold iridescence on the interior.  Super shape with an applied gold iridescent foot.  6" tall x 5" diameter.  Signed.  Mint condition.

Very fine vase with deep blue King Tut decoration on a butterscotch background.  6½" tall.  Signed.  Mint condition.

Quezal decoration and form is usually more precise than Tiffany. This example of a master salt is just that. It has exquisite applied, fluted feet and incredible color and iridescence. 4" diameter. Signed. Excellent condition except for some minor chipping underneath one leg and even more minor chipping on another.  It's such a wonderful piece that the small condition flaws should be overlooked.

Very nice vase with strong iridescence and red highlights.  8".  Signed.  Excellent condition.  (#31130)

Wonderful decoration on a great shape that I haven't had before.  Nice big size at 12".  Signed.  Mint condition (but with original imperfections to the top rim, as shown in the photos, only mentioned for accuracy).

Identical to the vase above but with an unfortunate crack to the base only.  It is probably original to the making when the foot was joined to the body and cooled.  Regardless, it's a gorgeous vase at a fraction of the price.  12".  Signed.
