The Oval Diamond Tennis Necklace
Fine Jewelry | Made to order
A full line of oval diamonds around the neck, each set east-west so the stones lie long against the skin. A classic tennis necklace, softened by the oval cut.
The Piece
One hundred and twenty-six oval lab-grown diamonds run the length of the necklace, each in a shared setting and linked into one flexible line. Set on their sides, the ovals cover more of the neck than rounds of the same weight, for a fuller, continuous line of light.

Why This Piece
A round tennis necklace is the default. Setting ovals on their sides covers more of the neck with each stone, so the same line reads longer and softer.
Designed to Be Lived In
Every Alva piece is made by hand in 14k gold and lab-grown diamonds, and made to order after you place it. It is measured by the years of wear ahead of it, not the moment it was bought.
Care
What's good is worn, not kept safe. A softened edge or a faint scratch is not damage; it is evidence of a life lived in it.
| Wearing it | Put it on last, after lotion and perfume have dried. Take it off first, before swimming, heavy exercise, or exposure to household chemicals. |
| Cleaning it | Clean with warm water, mild dish soap, and a soft-bristled brush. Rinse and dry with a soft cloth. Skip ultrasonic cleaners on delicate settings and abrasive polishes altogether. |
| Storing it | Store separately so metal does not scratch metal. |
| Professional care | Have the setting checked once a year. White gold may need replating every few years; yellow and rose gold simply deepen in color instead. |

Cared for simply, a piece settles further into a life, and the mark it takes on becomes part of what it is worth.
