Crafted in 18K gold, Tempus' intertwined design symbolizes paths that cross and become one. The structure is enriched with a delicate paving of set diamonds (0.16 ct total), creating a continuous sparkle.

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)

Custom Quote

Your ring journey begins with curation: we present genuine options, with certificates and transparent pricing — and you choose the gemstone that tells your story.

What is a natural diamond?

It's 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 is 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.

What are the 4Cs of diamonds?

The criteria used to evaluate diamonds are: cut, color, clarity, and carat. These determine the sparkle, purity, size, and value of the stone—whether natural or lab-grown.

At Vangolden, we work with natural diamonds of I color, VS2 clarity with excellent cut, and lab-grown diamonds of D-F color, VVS1 clarity, and excellent cut. Want to learn more about diamond grading? Read more here.
