FAQ

What makes a round brilliant cut diamond the most popular choice for an engagement ring?

Round brilliant cut diamonds are highly favored because their 57 or 58 facets are mathematically engineered to maximise light return, giving them more fire and brilliance than any other shape. Based on our decades of experience crafting custom rings in the US, round diamonds are exceptionally versatile and look stunning in various settings, from classic solitaires to intricate halos. Additionally, their symmetrical shape visually masks minor color tints and natural inclusions better than elongated cuts.

How do I choose the best combination of the 4Cs for a round diamond ring within my budget?

To maximize your budget, our gemologists recommend prioritizing Cut above all else, as an "Excellent" cut makes the diamond look brighter and even larger. For a round diamond, you can safely drop to a SI1 or SI2 clarity grade for an "eye-clean" stone (where flaws aren't visible without magnification). For Color, opting for a G, H, or I grade gives you a beautifully white appearance face-up when set in white gold or platinum, saving you up to 30% compared to flawless, colorless diamonds.


What is the difference between natural and lab-grown round diamonds for an engagement ring?

Chemically, physically, and optically, natural and lab-grown round diamonds are identical. Both rank a 10 on the Mohs hardness scale. The primary difference lies in their origin and long-term market value. Natural diamonds form deep within the Earth over billions of years and carry a rarity premium, retaining significant resale value. Lab-grown diamonds are created in a matter of weeks using advanced technology, allowing us to offer them at a much lower price point for the same size and quality.

Do your round diamond engagement rings come with independent grading certificates?

Every loose diamond and centre stone above 0.30 carats in our collection is strictly accompanied by an independent grading report from the GIA (Gemological Institute of America) or AGS (American Gem Society). These documents verify the precise cut, color, clarity, and carat weight of your gem. We firmly advise buyers against accepting in-house or unverified store appraisals as a substitute for an authentic GIA grading report.

What round diamond ring styles are most flattering for mature hands?

For mature hands, our design consultants generally recommend wider bands or multi-stone settings like a classic three-stone round diamond ring or a halo setting. As hands age, knuckles can become more prominent, and skin texture changes; very thin, delicate bands can sometimes accentuate this or spin uncomfortably on the finger. A slightly wider shank or a round brilliant center stone framed by a halo draws light across the hand, creating a balanced, proportionate, and deeply elegant aesthetic that is comfortable for daily, lifelong wear.

How do I choose a secure, comfortable round diamond ring setting if I have a very active lifestyle or sensitive skin?

If you have a highly active lifestyle or work with your hands, we highly recommend a low-profile four-prong setting or a sleek bezel setting, which completely encircles the round diamond in precious metal to protect its edges from impacts. Furthermore, if you have sensitive skin or a known nickel allergy, we firmly advise choosing Platinum. Unlike 14k or 18k white gold—which is alloyed with other metals and requires periodic rhodium replating—our platinum is 95% pure, completely hypoallergenic, and will never irritate your skin, regardless of age or daily activity level.

Why do round brilliant cut diamonds carry a higher price per carat than fancy shapes?

Round brilliant diamonds cost more per carat than "fancy shapes" (like oval, pear, or cushion cuts) for two primary gemological reasons. First, cutting a round diamond requires sacrificing the largest amount of the rough diamond crystal—typically 50% to 60% of the raw stone is discarded to achieve perfect 57 or 58-facet symmetry. Second, the global market demand for round diamonds is exceptionally high, which drives up the cost of raw materials. However, their superior light performance and ability to retain value over time make them a highly stable financial investment.

Which precious metal best complements my skin tone for a round diamond engagement ring?

Choosing the right metal depends entirely on your skin’s undertones. For cool undertones (characterised by bluish veins and a tendency to burn easily), platinum or 14k/18k white gold beautifully amplifies the icy brilliance of a round diamond. For warm undertones (greenish veins and skin that tans easily), traditional yellow gold provides a stunning, high-contrast warmth. If you have neutral undertones, you are in luck—both white and yellow gold look fantastic, though rose gold is an exceptionally popular, romantic choice that complements almost every skin tone uniformly.
