Little Miss Sunshine 0.25 ct Moissanite Engagement Ring in 18K Gold

Q: How do I find my ring size? And what if I get it wrong?

We offer the first ring size adjustment free of charge within 12 months of receiving your order. To ensure a more accurate measurement, we recommend having your finger sized at a jewelry store with a ring sizer. Additionally, we send a complimentary ring sizer with your order to facilitate this process. If you prefer, you can also consult our Size Guide .

Q: What's the difference between natural diamond, lab-grown diamond, and moissanite?

Natural Diamond : formed by nature over billions of years, extracted from mines. Each stone is unique, carrying rarity and history. Lab-Grown Diamond : produced with advanced technology, but with the same composition and properties as a natural diamond. Visually and chemically identical to natural diamonds, differing only in origin. Moissanite : a gemstone created in a laboratory from silicon carbide. It is not a diamond, but it has a very intense brilliance and even more colorful "fire," high hardness (9.25 on the Mohs scale), and a more accessible cost, making it a modern and durable alternative for engagement rings.

Size Guide

Measure an existing ring

To find your size, measure the internal diameter (in millimeters) of a ring that already fits you well. Place the ring on a ruler/caliper and measure the inside from edge to edge. Compare with the table:

BR Size	Internal Diameter (mm)
10	15.0
11	15.1
12	15.2
13	16.0
14	16.1
15	17.0
16	17.1
17	17.2
18	17.5
19	18.0
20	18.5
21	18.8
22	19.0
23	19.2
24	19.9
25	20.0
26	20.5
27	20.8
28	21.1
29	21.2
30	21.8
31	22.1
32	22.5
33	22.8

Tip: Measure at the end of the day and avoid measuring with cold fingers. If you're between two sizes, the larger one is usually more comfortable. If in doubt, contact us.

Measure your finger (paper strip or string)

If you don't have a ring as a reference, use a paper strip (or string) to measure the circumference of your finger and convert it to your ring size.

Cut a thin strip of paper (±5 mm wide) or use a thin string.
Wrap it around the finger where the ring will be worn. (Don't overtighten; simulate real comfort.)
Mark the meeting point with a pen.
Lay the strip flat and measure the distance between the marks in centimeters (cm).
Use your measurement in centimeters to find the corresponding size in the table below.

Reference table – finger circumference (cm) × BR size:

BR Size	Finger Circumference (cm)
10	4.8
11	4.9
12	5.0
13	5.1
14	5.2
15	5.3

Types of Gemstones

We work with three options for the center stone: Moissanite, Lab-Grown Diamond, and Natural Diamond. All are durable for daily wear. The ideal choice depends on desired brilliance, origin, and budget.

Moissanite

Intense brilliance and "fire" (greater dispersion than diamond).
High durability: hardness ~9.25 on the Mohs scale.
Excellent cost-benefit: striking appearance at an accessible price.
Available in various sizes and cuts.

Lab-Grown Diamond

It's a real diamond! (same physical and chemical composition)
Visually identical to natural, with a better size/price ratio.
Produced in a controlled environment; Gemological certificate for gems over 1 ct (upon request).

Natural Diamond

Rarity and tradition: formed in nature over millions of years.
Maximum hardness (10 Mohs) and classic diamond brilliance.
Available with gemological certification for gems over 0.30ct (upon request)

Rarity and traditional value → Natural Diamond.

Still in doubt? Talk to our team — we'll help you compare sizes, colors, and cuts within your budget.

Durability

Moissanite occupies a unique position: it does not replace diamond, but it is the closest alternative in terms of brilliance, strength, and durability.

Luminosity

Moissanite stands out for its intense brilliance and vivid play of colors, a result of a higher refractive index than that of diamond.

Authenticity and Classification

All moissanites above 0.50ct come with a GRA certificate, which ensures the authenticity, specifications, and quality of the gem.

Gems and Raw Materials

Is moissanite a diamond?

No. Although visually similar, moissanite and diamond are different minerals. Moissanite is made of silicon carbide, while diamond is crystallized pure carbon.

What's the difference between natural diamond, lab-grown diamond, and moissanite?

Natural Diamond: formed by nature over billions of years, extracted from mines. Each stone is unique, carrying rarity and history.

Lab-Grown Diamond: produced with advanced technology, but with the same composition and properties as a natural diamond. Visually and chemically identical to natural diamonds, differing only in origin.

Moissanite: a gemstone created in a laboratory from silicon carbide. It is not a diamond, but it has a very intense brilliance and even more colorful "fire," high hardness (9.25 on the Mohs scale), and a more accessible cost, making it a modern and durable alternative for engagement rings.

Does Moissanite lose its sparkle over time?

No. Like diamonds, it maintains its brilliance and transparency throughout its life, provided it receives basic cleaning and care.

What does "18k" mean in jewelry?

“18k” indicates that 75% of the alloy is pure gold and 25% consists of metals that provide strength and color. It is the most commonly used standard in fine jewelry due to its combination of beauty and durability.
