Is moissanite a good diamond alternative?

Moissanite is harder than most gemstones and very bright, with more colorful fire than diamond. It reads as a large, sparkly stone; it is not a diamond and does not hold value like one.

What does the 1.25 carat figure mean?

It refers to the pear center stone, about 6x8mm. The bubble band stones are small round cuts, 2mm and 0.9mm, so the set's total weight is higher than the center alone.

Which metal should I pick?

Sterling silver is the entry option and tarnishes over time. 14k gold is the common middle choice for daily wear; 18k gold and platinum are softer-colored or more durable upgrades.

Can the rings be worn separately?

Yes. The set is a solitaire, a plain band and a half-eternity bubble band, so each can be worn alone or stacked in different orders.

How should I care for the set?

Clean with mild soap and warm water and a soft brush, and check the prongs and pave stones regularly. Remove it for gym, gardening and harsh chemicals.
