A picture would sure help.
Squatty ? How tall is it? How wide is the base?
Does it have the IG mark?
Ripple vases were reproduced using the original molds in the 60’s

If the flaw is in the making it does not diminish value. (IMHO)

I agree with Wally, if the flaw is original from time of manufacture then it usually does not diminish the value. However you will want to be sure of what TYPE of flaw it is and disclose it in your item description of course.

The link below takes you to the Glass & Pottery Sellers Association Glossary of Flaws and Defects, it is a great resource.

I believe what you are describing might be a type of mold mark known as a “straw mark”, though it’s hard to say for sure without seeing a photo.

you should 1. always take a picture of the flaw to be picture#4 and describe it as you see it and as ([URL removed] in photoview #4).
2. if you are selling antique or vintage glass you should educate yourself on it by visiting B&N or Borders book stores and read the antique books if you can’t afford them or at least google the company and learn about them and how things were manufactured.

3. you may learn that such a crease in blown glass item is from a lax in the rotation of the handler/blowers’ arm during the twirling of the glass.

4. if pressed glass; it is considered a mold crease rather than a crack or defect.
I don’t mean to sound smug but if you want to sell antique glass you should now what your dealing with so that you receive top value and not sell under value—-which devalues the items and robs other glass dealers of their just recompense.

Picture please.

I’ll second the straw mark theory :)

I think if you are perfectly honest with your description, a buyer would be willing to buy it flaw or not. I once sold a pair of used Mickey Mouse shorts with a hole in them for $25.00.

Without seeing it but from description sounds like a straw mark. If so I concur you should mention in description but should not diminish value.

It depends on what the flaw is for sure. If it is a flaw it can effect value slightly…depending on how bad it is, and what it is.

If it is a flawing from manufacturing which does happen with glass it will not effect the value.

It needs to be noted either way, but you really do need to find a way to better determine what the flaw is to better help you, and inform customers with your listing too.

Good Luck :)

Most time factory imperfections that don’t effect the appearance of an item do not relate so long as they don’t effect durability and use.
