Is moissanite a good choice for an engagement ring?

Moissanite is hard and durable enough for daily wear and has more fire than diamond. It is not a diamond, so it looks slightly different in some lighting and has lower resale value.

What does DEF color and VVS+ clarity mean here?

DEF places the stone in the colorless range on the diamond color scale. VVS+ means very, very slightly included or better, so any inclusions are hard to see without magnification.

Which center stone weight should I pick?

The 1.50CT reads as a classic, balanced size on most hands. The 2.50CT and 3.50CT give a larger, more statement look and suit wider bands or bigger hands.

How do I choose between 10K, 14K and 18K gold?

10K is the most durable and least yellow. 14K balances durability and color for everyday wear. 18K is the richest in color and softest, so it scratches more easily.

Will a 2.0 mm band hold up to daily wear?

A 2.0 mm band is on the slim side. It is fine for regular wear but can bend or wear thinner over years, so consider a slightly wider band for very active hands.

Does the heart cut sparkle like a round brilliant?

It has strong brilliance but a different pattern than a round brilliant. The heart shape concentrates light in the lobes and point, so expect a softer, more romantic sparkle.
