Good to know

The Promise collection presents single stone rings where a solitary diamond takes centre stage, embodying the union of two complementary beings. Each ring reveals clean lines and balanced proportions that highlight the diamond’s presence and the gold’s subtlety.

Single Stone Rings Promise Collection: What It Includes

See more

This selection features rings set with a single diamond, crafted in or jaune, blanc, or rose, with a choice of 9 or 18 carats gold. The designs vary from fine to more substantial bands, each emphasizing the diamond’s cut and clarity. The Promise collection focuses on simplicity and precision, allowing the light to play freely on the diamond’s facets. The rings are available in different gold colours to suit personal taste and budget, with the 9 carats option offering accessibility and the 18 carats option containing twice as much fine gold.

Choosing a Single Stone Ring in the Promise Collection

Deciding between or jaune, blanc, or rose depends on the desired contrast with the diamond and personal preference. The gold’s colour influences the ring’s overall tone, while the carat weight of the gold affects its density and price. The band’s width and profile also impact comfort and style—fine bands offer delicacy, while wider bands provide a stronger presence. The solitaire design focuses attention on the diamond, so selecting the right cut and size is essential to balance brilliance and wearability.

Edenly offers a 2-year guarantee and a certificate of authenticity with each ring. The Promise collection rings are designed to accompany a wearer throughout life’s exceptional moments.

How should I care for a single stone ring in the Promise collection?

Clean the ring regularly with a soft cloth and avoid abrasive products. Remove it for swimming, sports, or cleaning to protect the gold and diamond. Store it separately to prevent scratches. White gold rings have a rhodium finish that may wear over time; Edenly covers re-rhodiation under its 2-year guarantee.

What is the difference between 9 carats and 18 carats gold in these rings?

The difference lies in the fine gold content: 37.5% for 9 carats and 75% for 18 carats. The 9 carats option makes the ring more accessible, while 18 carats contains twice as much fine gold. The choice depends on budget and preference.

Can the Promise single stone rings be personalized?

Edenly offers an online creation tool to design a ring by choosing the setting, gold colour, and diamond. This allows for a tailored ring that reflects personal taste and the significance of the moment.
