Triangulum Band

£240

The Triangulum is part of our collection of placeholder rings – temporarily taking the place of an engagement ring, it allows the couple to chose a design or create a bespoke piece together once the proposal has taken place. Our placeholder rings become treasured pieces of jewellery in their own right, wearable on another finger after a more formal engagement ring is made, as a keepsake of each couple’s love story.

The Triangulum Band features a small white round diamond inset into a trompe-l’oeil triangular setting on a flat band.

Additional Information

Stones & Price Information

In an effort to keep our placeholder rings as accessible as possible, they are exempt from the complimentary resize we usually offer as standard with our rings.

If you'd like to move ahead with a Rachel Boston engagement ring after purchasing one of our placeholders, we will resize the latter once at no additional cost. Resizing otherwise costs £90, to cover our craftspeople's time. We appreciate your understanding!

Product Details

Available in 9ct White, 9ct Yellow and 9ct Rose Gold.

Made from start to finish in the UK using 100% recycled precious metals.

9ct gold jewellery is made from a durable alloyed blend of gold and other metals, offering a timeless and elegant finish. While 9ct gold is more resistant to tarnishing than gold-plated alternatives, it may still develop a natural patina over time.

Tarnishing can be influenced by factors such as exposure to moisture, chemicals, and even individual pH levels, which may cause some pieces to tarnish more quickly. To maintain its shine, we recommend removing your jewellery before bathing, showering, swimming, exercising, or applying perfume, hairspray, or lotion.

Tarnish is easy to remove using a soft jewellery polishing cloth or a gentle gold dip solution. We also offer a polishing service in our showroom to help restore your jewellery's shine. Additionally, we can create custom pieces in 18ct gold upon request. Please email hello@rachelboston.co.uk for a quote in 18ct.
