How to Choose the Perfect Solitaire Ring?
The beauty of a solitaire lies in the details. When the focus is on a single stone, every choice – from the diamond’s origin to the prong setting- matters.
1. The Diamond Choice: Lab-Grown vs. Natural
- Lab-Grown Solitaires: The smart choice for those who want a larger, higher-clarity center stone for their budget. You can often secure a 1.5ct or 2ct lab diamond for the price of a much smaller mined stone.
- Natural Solitaires: Perfect for those who value the geological rarity and traditional “heirloom” status of a diamond from the earth.
- The Rossia Guarantee: Every solitaire stone is IGI or SGL Certified, ensuring your diamond’s 4Cs (Cut, Color, Clarity, Carat) are independently verified.
2. The Metal Choice: 14KT vs. 18KT Gold
- 14KT Gold: Highly recommended for daily-wear lab-grown solitaire diamond rings. Its added alloy strength makes the prongs more resistant to bending and the band more scratch-resistant.
- 18KT Gold: The choice for pure luxury. It offers a richer yellow-gold tone and a heavier feel on the hand, ideal for those with sensitive skin or a preference for high-purity gold.
3. Selecting the Diamond Shape
In a solitaire, the shape defines the ring’s personality:
- Round Brilliant: For the classic buyer who wants the maximum light return and sparkle.
- Oval & Pear: These elongated shapes create a slimming effect on the finger and often appear larger than a round stone of the same weight.
- Emerald & Radiant: For those who prefer a sophisticated, architectural look with unique light reflections.

At Rossia Jewels, you can explore solitaire rings in various cuts and styles
The shape of your diamond is the first thing people notice. While “Cut” refers to the stone’s ability to reflect light, “Shape” defines its personality. At Rossia Jewels, our manufacturing expertise allows us to set any of these iconic shapes in 14KT or 18KT gold, using either Lab-Grown or Natural diamonds.
1. Round Brilliant Cut: The Timeless Icon
The Round Brilliant Cut is the gold standard of sparkle. Engineered with 57 or 58 facets, it is designed to maximize light return and fire.

Founders’ Note: The Power of One
“There is a unique honesty in a solitaire ring. It doesn’t hide behind accents or halos; it lets the diamond speak for itself. When I founded Rossia Jewels, I wanted to ensure that every solitaire ring we manufactured – whether in 14KT or 18KT gold – was a masterpiece of balance and strength.
As a manufacturer, I see the care that goes into ‘seating’ a diamond perfectly. We don’t just sell you a ring; we provide a symbol of your most significant promise, crafted with uncompromising quality and direct-from-factory transparency. Thank you for letting us be part of your story.”
Frequently Asked Questions about Lab Grown Solitaire Diamond Rings
- Is a 4-prong or 6-prong setting better for a solitaire?
A 4-prong setting allows more light to enter the diamond, increasing sparkle, while a 6-prong setting offers more security and can make a round diamond look more circular. As manufacturers, we can customize this as per your preferences.
- Can I wear my 18KT solitaire ring every day?
Yes, but with care. 18KT gold is softer than 14KT gold. If you have a very active job or lifestyle, we recommend our 14KT gold settings for better scratch resistance and prong durability.
- Does a solitaire make the diamond look bigger?
A solitaire focuses all attention on the center stone, but choosing an elongated shape like an Oval or Marquise can make the diamond appear significantly larger than a standard round cut.
- Are Rossia solitaires certified?
Yes. Every solitaire center stone at Rossia Jewels is accompanied by an IGI or SGL certification, ensuring you have an independent report on the quality of your diamond.
- What is the most popular solitaire diamond shape for 2026?
While the Round Brilliant remains a timeless icon, Oval and Elongated Cushion cuts are the top trends for 2026. These shapes are highly sought after because their elongated silhouette flatters the finger and often appears larger than a round diamond of the same carat weight. At Rossia Jewels, we offer these trending shapes in both Lab-Grown and Natural diamonds, handcrafted to your exact specifications.
- How can I make my solitaire diamond look bigger?
To maximize the visual size of your solitaire without increasing your budget:
- Choose Elongated Shapes: Ovals, Pears, and Marquise cuts have a larger “face-up” surface area.
- Opt for a Slim Band: A thinner 14KT gold band creates a contrast that makes the center stone appear more prominent.
- Consider a Hidden Halo: This 2026 trend adds a secret circle of diamonds under the main stone, providing extra sparkle without distracting from the solitaire’s minimalist look.
- Which solitaire rings should I buy – Lab-Grown vs Natural Diamond?
- Lab-Grown Solitaires: The smart choice for those who want a larger, higher-clarity center stone for their budget. You can often secure a 1.5ct or 2ct lab diamond for the price of a much smaller natural diamond.
- Natural Solitaires: Perfect for those who value the geological rarity and traditional “heirloom” status of a diamond from the earth.
- At Rossia Jewels, we start by educating about differences and guide them to make informed decisions. All our designs come with a choice – Lab-Grown Diamond OR Natural Diamond.
