The Aeterna Archive
Aeterna means eternal. The archive gathers the designs fine jewellery keeps returning to: a halo of small diamonds around the centre stone, a band edged in milgrain, the tiny raised beads of gold, floral and geometric halos drawn from older rings, and necklaces that grow towards the throat. Choose one as an engagement ring with a sense of history, or as an anniversary piece with presence enough for black tie.
Look at the rings in profile before you choose. Many keep their finest detail beneath the centre stone, in a second halo or a gallery of small diamonds that only the wearer sees. A halo also makes the centre stone look larger than its carat weight.
Grown, not mined. A lab-grown diamond is physically, chemically and optically the same as a mined diamond. It is graded on the same scale for cut, colour, clarity and carat, and every Diamos diamond carries an independent IGI report.
Cut comes first. Cut decides how much light a diamond returns to your eye. A well-cut stone of a smaller carat will often look brighter, and larger, than a poorly cut stone that weighs more.
Shape changes the look on the hand. Oval, pear and marquise cuts spread across more of the finger than a round of the same weight. Emerald and Asscher cuts trade sparkle for long, calm flashes of light and reward higher clarity.
Choose your gold with your skin tone in mind. White gold sharpens a colourless stone, yellow gold adds warmth, and rose gold softens the whole piece. We set in 9K, 14K and 18K BIS hallmarked gold.
