A Christmas ornament(ball) inspired by the fabergé egg, made for the Russian Tsars Alexander III and Nicholas II as Easter gifts for their wives and mothers by House of Fabergé(1885-1917).
For many years I have been decorating the Christmas tree in Lego(large family, big tree), but I have always had difficulty creating large and light elements.
Here is a solution that can be built in many LEGO COLORS, lightweight and high volume(using only 194 bricks).

Difficult construction, be patient, requires dexterity of hands.
Once built it is a solid structure.

Give some space between (Dish 6 x 6 Inverted) and (Plate, Modified 2 x 2 with Bar Frame),
during construction, tighten at the end.
