Hi Jake,

Thank you for contacting Mearto with your appraisal inquiry - this is a lovely marble mantel / fireplace surround! (on an aside, the term 'fireplace' refers to the box-like area where the fire is, so if you're looking to sell this, having the right terminology is important)

White marble mantels and fireplace surrounds have long symbolized elegance, permanence, and refined craftsmanship. Popular from the late 18th century through the early 20th century, they were inspired by Classical Greek and Roman architecture and became hallmarks of Georgian, Federal, Victorian, and Beaux-Arts interiors. Their luminous stone showcases intricate carving while complementing virtually any décor, from traditional to contemporary. Beyond their beauty, marble mantels are prized for their durability, architectural presence, and ability to serve as a dramatic focal point that enhances both historic homes and modern living spaces.

I agree that this is likely from the late 1800s - the style of this fireplace aligns with the Rococo Revival period that was popular during the late 19th Century (think the HBO series 'The Gilded Age,' though mantels in those Newport mansions are much larger and grander in scale).

The market for marble mantels and fireplace surrounds is varied but I've found a few ones similar in size and style that have sold at auction recently that suggest this would probably sell between $3,000 and $5,000, possibly more if offered for auction at an auction house with a good reputation for architectural elements such as this.

If you're looking to sell this privately, I strongly suggest asking $7,000 or more so as to avoid the risk of underselling it.

Based on the photos and information provided, and subject to examination, this is:
