Lumen Solitaire

About Lumen Solitaire

Emerald cut solitaire engagement ring setting crafted for those who appreciate clean lines, architectural precision, and understated elegance. Lumen Solitaire is a refined emerald cut solitaire — minimal, deliberate, and designed to let your chosen center stone command every room.

This product is sold as a setting only. After selecting Lumen Solitaire, you choose your preferred center stone type: natural diamond, lab-grown diamond, gemstone, or a coloured lab stone. This gives you complete control over the look, ethics, and budget of your finished ring.

The emerald cut is one of the most architecturally striking choices in fine jewellery. Its long, rectangular step-cut facets create a hall-of-mirrors effect that is entirely unique — unlike brilliant cuts, the emerald cut solitaire engagement ring rewards clarity and precision. Every facet is visible, every detail intentional. Lumen’s clean 4-prong setting holds the stone securely at each corner while keeping the gallery completely open, allowing light to travel freely through the stone.

For those drawn to structure and sophistication, the emerald cut solitaire engagement ring is the definitive choice. Lumen’s plain polished band tapers gently toward the head, creating a balanced, timeless silhouette that works beautifully in all three gold tones.

This emerald cut solitaire engagement ring setting is crafted exclusively in solid 18K gold, available in:

• 18K White Gold — crisp and contemporary, enhancing the icy clarity of the emerald cut
• 18K Yellow Gold — warm and classic, a timeless pairing with step-cut stones
• 18K Rose Gold — soft and romantic, adding warmth to the clean geometric lines

Every Lumen Solitaire ships with free insured delivery across Europe. EU customers pay no customs fees. Your ring arrives in secure, discreet packaging — ready to be presented exactly as you imagined.

Whether you are drawn to a natural diamond, a lab-grown stone, or a coloured gemstone, this emerald cut solitaire engagement ring setting is designed to honour your choice with the craftsmanship it deserves. If you need help choosing your stone, metal, or size, our team is always available.

Frequently Asked Questions

Is Lumen Solitaire a complete ring or a setting only?

Lumen Solitaire is sold as a setting only. The center stone is not included and is selected separately after you choose the setting.

What makes Lumen an emerald cut solitaire engagement ring?

An emerald cut solitaire engagement ring features a single rectangular step-cut stone with no side stones. Lumen’s 4-prong corner setting holds one emerald cut center stone, keeping the design clean, architectural, and timeless.

Why choose an emerald cut for an engagement ring?

The emerald cut is prized for its elegant, elongated silhouette and its distinctive step-cut facets that create a deep, mirror-like brilliance. It is a sophisticated alternative to round brilliant cuts and suits those who appreciate understated, architectural beauty.

What is the difference between a natural and a lab-grown diamond?

A natural diamond is mined from the earth. A lab-grown diamond is chemically, physically, and optically identical — created in a controlled environment. Lab-grown diamonds typically cost 50–70% less than natural diamonds of the same quality.

Can I choose a coloured stone for the Lumen setting?

Yes. Lumen Solitaire is compatible with a natural gemstone (such as sapphire or emerald) or a coloured lab stone in an emerald cut. Book an appointment for guidance.

What metals is Lumen Solitaire available in?

Lumen Solitaire is available in solid 18K White Gold, 18K Yellow Gold, and 18K Rose Gold. All metals are solid 18K — not plated.

What is the difference between 18K white, yellow, and rose gold?

18K White Gold has a bright silvery finish. 18K Yellow Gold is the classic warm gold tone. 18K Rose Gold has a warm pinkish hue. All three are equally durable for daily wear.

Will Lumen Solitaire pair well with a wedding band?

Yes. The clean, straight profile of Lumen Solitaire pairs beautifully with most straight or fitted wedding bands. Browse our Wedding Bands collection to find a matching band.
