Aura Lab-Grown Diamond Ring - 2.00ct Oval

Q: What are the 4Cs of diamonds?

These are the criteria used for evaluation: cut, color, clarity, and carat . They determine the brilliance, purity, size, and value of the stone — whether natural or lab-grown. At Vangolden, we primarily work with natural diamonds of color I , clarity VS+ , and excellent cut, and with lab-grown diamonds of color D–E–F , clarity VVS1 , and excellent cut, always seeking a balance between beauty, brilliance performance, and value. However, if you desire another quality range — whether to adjust the budget or follow a specific preference — we can also select diamonds with different characteristics, always transparently explaining the differences in color, clarity, and price to ensure an informed choice.

The Aura combines lightness with intensity.

The central gem, a 2-carat (approx. 9x7mm) oval lab-grown diamond, is set with four prongs.

Along the band, smaller lab-grown diamonds are set in an asymmetrical arrangement, with varied sizes that create movement and depth.

All jewelry comes with our certificate of authenticity and warranty, gem certificate (when applicable) and invoice.

IGI certificate available.

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)

Aura Lab-Grown Diamond Ring - 2.00ct Oval

R$ 12.490,00

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)

Quick Comparison

Characteristic	Moissanite	Lab Diamond	Natural Diamond

Origin	Laboratory	Laboratory	Natural
Relative Price	$$ (more accessible)	$$$	$$$$
Certification	GRA above 0.50ct	Certificate upon request above 1 ct	Certificate upon request above 0.30ct

Note: The final appearance depends on factors such as cut, color, and clarity of each piece.

How to choose?

FAQ — Our Diamond

Vangolden diamonds combine natural and lab-grown stones selected for what truly matters: cut, visual clarity, and presence in the design. Check out our complete selection.

About the diamond

What is a natural diamond?

It is a gem formed by the Earth over billions of years, under high pressure and temperature. Each stone carries rarity and a unique history.

What is a lab-grown diamond?

It's a lab-grown diamond created in a controlled environment with advanced technology. It has the same composition and physical and chemical properties as a natural diamond.

Which is more durable: natural diamond or lab-grown diamond?

In terms of durability, they are equivalent.

Both have a hardness of 10 on the Mohs scale, the maximum possible, and behave the same way in daily use, meaning that virtually no other material can scratch them, except another diamond.

However, it is important to understand that the Mohs scale measures scratch resistance, not "indestructibility" or impact resistance (toughness). In other words: natural and lab-grown diamonds are not unbreakable – a strong blow, pressure on edges, or a sudden shock can chip or break the gem.

Therefore, what truly guarantees the stone's security is much more about the well-executed cut, how it is set in the jewelry, and daily care, rather than its natural or lab-grown origin.

What are the 4Cs of diamonds?

These are the criteria used for evaluation: cut, color, clarity, and carat. They determine the brilliance, purity, size, and value of the stone — whether natural or lab-grown.

At Vangolden, we primarily work with natural diamonds of color I, clarity VS+, and excellent cut, and with lab-grown diamonds of color D–E–F, clarity VVS1, and excellent cut, always seeking a balance between beauty, brilliance performance, and value.

However, if you desire another quality range — whether to adjust the budget or follow a specific preference — we can also select diamonds with different characteristics, always transparently explaining the differences in color, clarity, and price to ensure an informed choice.

Want to learn more about diamond grading? Read more here.

Do lab-grown and natural diamonds come with certificates?

Yes. Here at Vangolden, we offer recognized gemological certificates for lab-grown diamonds from 1 ct and for natural diamonds from 0.30 ct upon request.

Below these sizes, we work with a strict quality curation, following criteria for cut, color, clarity, and carat, always with transparency about the characteristics of the gem.

How to choose between natural and lab-grown diamonds?

If you value tradition, geological rarity, and the history of owning a gem formed by the Earth itself above all else, and don't mind investing more for it, a natural diamond is the most suitable choice.

If you want a real diamond, with the same beauty and durability, but prefer a more rational use of your budget—whether it's to get a larger stone, one with better color and clarity, or to balance it with other plans for the couple—a lab-grown diamond makes a lot of sense.

Ultimately, the ideal decision is one that balances three points: how you feel when you look at the jewelry, what comfortably fits your budget, and what makes the most sense for the story you want to tell with this ring.
