Wood sphere display stands for crystal balls and eggs, measuring the top portion as indicated in the photos. Colors vary from greyish brown to darker reddish brown. Actual measurements can vary by .1" +/- since they're hand made. My personal preference on sizing is...

[1.2"] Spheres 1.1" to 3"
[1.5"] Spheres 1.7" to 3.5"
[1.9"] Spheres 2.3" to 3.8"
[2.2"] Spheres 2.8" to 4.5"
[2.9"] Spheres 3.5" to 6"
[3.1"] Spheres 3.8" to 8" 
[3.6"] Spheres 4.6" to 9"
[4"] Spheres 5.2" to 12"+

HOW TO MEASURE YOUR SPHERE: Sandwich it on a level countertop or bookshelf, using the wall or fridge and another square or rectangular item like a box of tissues. Measure the distance between the two with a ruler, or compare to something you know the length of.
