Solitaires, pavé bands, and bespoke settings in solid 14K gold, each stone IGI certified to the same standard as a mined diamond. Custom sizing is available on every design.
This collection is the doorway into the Ring Builder, not a finished catalogue - rings are made to order, so the decision here is less about browsing a fixed set of designs and more about choosing the three things that actually define the piece: diamond shape, setting profile, and gold colour. Solitaire settings put all the attention on the stone and suit those who want a timeless look; halo and pavé settings add visual size without adding carat weight, which matters if budget is the constraint rather than presence. White gold is the most requested colour for engagement rings, though rose and yellow both wear well with warmer skin tones. Every ring is built around an IGI-certified diamond in solid 14K gold, sized and finished to order rather than pulled from stock.
A lab-grown diamond ring uses a diamond created in a controlled environment rather than mined from the earth. It's identical in composition and appearance to a mined diamond, certified by IGI, and often prices lower than mined diamonds with similar listed specs.
14K gold is the most practical choice - durable enough for daily wear, available in white, yellow, and rose, and less prone to scratching than 18K. It's the standard we use across all Carat Theory rings.
Wrap a thin strip of paper around your finger at the base, mark where it overlaps, and measure the length in millimetres. Divide by 3.14 to get your diameter, then match to a standard ring size chart. Evening is the best time to measure - fingers are slightly larger.
Yes. Because lab-grown diamonds are structurally identical to mined diamonds, the ring can be resized by any jeweller who works with fine gold settings.
A solitaire features a single centre diamond - classic and timeless. A pavé ring has small diamonds set closely along the band, adding sparkle alongside the centre stone. Both styles are available in lab-grown diamonds.
Once a week for everyday rings is ideal. A warm soapy soak and a soft brush keeps the stone brilliant and the setting free of skin oils that dull the diamond's sparkle over time.
