The Round Brilliant Cut diamond sparkles the most because its 58 facets are precisely engineered to maximize light reflection, creating unparalleled fire and brilliance, making it the top choice for sparkle, though Fancy Cuts like Princess or Oval offer intense sparkle with unique modern or classic looks.
Round brilliant cut is the most sparkly of all shapes. Cut grades range from Poor to Excellent, with symmetry and polish affecting performance. Fancy shapes like oval, cushion, and princess offer unique sparkle patterns.
The more facets a diamond has, the more reflective surfaces there are to bounce and scatter light. A round brilliant cut diamond with its 57 or 58 facets will appear to have more sparkle than a single-cut diamond with only 17 or 18 facets.

Moissanite is actually more brilliant than a diamond!
Brilliance, which refers to a stone's ability to reflect white light, is a good measure for how much a gemstone will 'sparkle'. Moissanite's brilliance is higher than diamond's due to its higher “refractive index” (Diamond's is 2.42, whereas Moissanite's is 2.65).
Diamonds have a higher refractive index than cubic zirconia, which means they tend to sparkle more intensely. Diamonds also display a sharper brilliance and distinct fire. Cubic zirconia tends to show a more pronounced rainbow-like effect, which can appear more artificial in certain lighting.
The Aquamarine name comes from the Latin word for seawater and is said to calm waves and keep sailors safe at sea. It is sometimes referred to as a poor man's diamond because of the pale color.
Moissanite also has far more sparkle than cubic zirconia, which can become cloudy over time. Moissanite is known for its bright, multicoloured reflections while cubic zirconia can lack the brilliance associated with white gemstones.
The round-shaped diamond (also known as the brilliant diamond) has the best sparkle. It has 58 facets, which means that light can pass through it in an optimum way and reflect off the many sides, creating the perfect sparkle. If you're looking for a gemstone with the most sparkle, choose a round-shaped diamond.
If you are looking for the best replacement for diamond (diamond substitute), then moissanite is the answer to your quest. This gem has more brilliance and fire than lab-created diamonds and natural diamonds. It also has more clarity, beauty, and durability than cubic zirconia.
Cubic zirconia does become cloudy over time due to surface abrasions, usually within a couple months of consistent wear. Moissanite, meanwhile, will not become cloudy over time if you give it the proper care. However, moissanite can become discolored due to high heat exposure.
The "3-month ring rule" is an outdated marketing guideline suggesting spending the equivalent of three months' salary on an engagement ring, a concept created by De Beers to boost diamond sales, evolving from earlier one and two-month suggestions. Today, it's widely seen as a myth, with most couples prioritizing personal financial comfort, open communication, and meaningful choices over this arbitrary rule.
The first thing you look into is the metal band, as it plays a major role in the durability and aesthetic of the engagement ring. High-quality rings are typically made with platinum, 18-karat gold, or high-grade white gold. These metals not only offer a luxurious finish but are also resistant to tarnishing and wear.
Because inclusions are more visible in diamonds with larger, open facets, you should pick VS1 over VS2 when choosing diamonds in shapes other than round (particularly in step-cut diamonds such as emerald-cut or Asscher cut).
FAQs

Taylor Swift's engagement ring features a large, antique Old Mine Brilliant Cut diamond, which is a vintage style with rounded corners, a high crown, and large facets, giving it a soft, candlelit sparkle rather than sharp modern flashes, often described as an elongated cushion shape with a small, open culet. This historical cut, popular in the 18th and 19th centuries, was chosen for its romantic, nostalgic character, perfectly suiting the ring's yellow gold setting with hand-engraved details.
Goshenite is a colorless gem variety of beryl. It is sometimes called the “mother of all gemstones”because it can be transformed into other gems, such as emerald, morganite, or bixbite.

The Cons: It's just not a traditional diamond
If you're set on tradition, or you want a stone that holds resale value, moissanite might not be your first choice. While it's beautiful and durable, it doesn't carry the same prestige as diamonds, and some jewelers or jewelry lovers may not see it as a true equal.
Cubic zirconia offers an affordable and visually appealing option for temporary or occasional use but is less durable. For those seeking a more sustainable, high-quality alternative to diamonds, moissanite is often the better choice.
Cubic Zirconia Cons:
Softer than diamonds at an 8-8.5 on the Mohs Scale of Hardness and therefore more prone to damage. Will become cloudy over time because of how easily it is scratched. Needs to be replaced every two years (on average) due to wear and tear. Not rare and therefore has little to no value.
