Thank you for contacting Mearto and I apologize for the delay. This is a pair of tusk-shaped bone tile sculptures from China. They appear to be 20th century, based on the style. Usually, the stones in inlay work like this are soapstone and nephrite. There are bone tile sculptures on the market that sell for under $1000, although I was not able to find pieces as big as these. A pair of 40” vases sold for $600, and a set of bone tiled tusks for $2000. I have added links below.

As far as actual elephant tusks, the sales prices would be higher. I think it depends on whether these are authentic tusks or made from a different material like plaster. Looking at your pictures, I can’t know for certain. Can you see whether they are identical in shape? I think if they are not exactly the same in height/slope/etc. we can be more sure that they could be real. Another way is to try to look at the underlying material. Are there any areas where there is room between the tiles? You can ID ivory by looking at it and also with a pin test. I put a link below to a site with a description of how to identify ivory. If these are ivory, be sure to look into rules on legality if you decide to sell. There may be regulations depending on your location.

My estimate above is based on these not being ivory. Past hammer prices of authentic tusks (see links) are very scattered. Based on price per kg of ivory in 2020, the value in weight would be $5,290.
