Hi Elizabeth, pleased to hear from you! Regrettably, wood furniture which is made at different times is always going to have a slightly different finish. You can use a wax polish if you feel this help and, over time, the finish will enhance and the colour change may be not so noticeable.
When using a wax polish always make sure the surface is dust free since even very tiny specks of dust can act as abrasive and cause very fine scratches. And also always use a soft clean, lint-free natural cotton cloth.
Best wishes and thanks again for getting in touch.
