Thank you for contacting Mearto with your appraisal inquiry.
It is a beautiful set of candlesticks and vase. Such items are being offered at auction on a regular basis.
It was made by Jens Harald Quistgaard who was a Danish designer, it was made in the 1960s. The material is silvercoloured metal or perhaps silverplated metal - hard to tell from the photos.
It is very decorative and the 1960s style is in fashion at present however the material the items are made of is not expensive which affects the price.
The estimate provided is for a well-advertised specialised online design auction, where I believe the candlesticks and vase has the best chance of realising its fullest potential. However, there is no measurement for the sentimental value you might attach to the designer items. Retail "asking prices" can be higher and vary.
Please let me know if you have any additional questions. I’m happy to help.
