Rare Vintage One of a Kind Pair of Crystal Candle stick holders For Sale

This is a beautiful pair of unsigned crystal candle sticks. The light reflection off of these made them difficult to take pictures of. Many pictures appear blurry due to the light refraction.
The height of each is 9.75 inch, base width is 3.71 inches and the widest area on the top is 3 inches. The pair weigh 4 1/2 lbs.I purchased these many years ago at an estate sale of a women who traveled all over the world collecting high end crystal. These were the tallest, heaviest and most beautiful of all the hundreds of candles sticks for sale and were priced the lowest at $350.00.
The crystal appraiser for the estate was present at the sale. He told me that it was not known until after the of the death of the crystal owner that these were unsigned. The crystal appraiser was not able to identify the maker of them. They were kept in a display cabinet where the women had all her Swarovski items and her daughter told me she usually did not mix brands in her cabinets so the family always presumed they were made by Swarovski.
The crystal appraiser pointed out a few areas on both candle sticks he believed were inclusions that were exposed during the cutting and polishing process of making the candle sticks. He also pointed out that the diamond polishing had not been finished on the tops of both bases. One base is less finished than the other. He concluded that these candle sticks were probably a commission job that was stopped due to the exposure of the inclusions. He said that when production is stopped on a job due to inferior results the item is usually smashed and not allowed to be sold. He was surprised an unfinished product was sold. The appraiser also said these could have been made at any crystal factory because there is no signature on them. He thought they did look like Swarovski in design. He offered to make a written appraisal for me for $100.00. I wish I had done that now.
I have never seen another candle stick like these so they may be one of a kind.
I have priced these at less than half of what I paid for them and tried to show all the defects in the pictures. I am moving to a small retirement apartment and will not have room for my display cabinet. These are being sold "as is". I am not able to take returns. Please send me a message if you have other questions or if you may know the origins of this pair of candle sticks.
