Old-world glamour with a celestial heart. The Lilith Herkimer diamond engagement ring set frames a natural coffin-cut quartz crystal — a genuine Herkimer “diamond” whose salt-and-pepper inclusions glimmer like the night sky — in an Art Deco setting of geometric filigree and bright simulated diamond accents. Handcrafted as a matched pair in solid 925 sterling silver with a rhodium finish, it is a 1920s-inspired proposal ring and band built for a love that transcends time.

Art Deco romance, reimagined
Inspired by the glamour of the 1920s, the setting carries the geometric patterns and delicate filigree of the Art Deco era — all sharp symmetry and opulent detail around the elongated coffin-cut crystal. Paired with its matching band, it is a wearable work of art for lovers of vintage-inspired bridal and bold, architectural silhouettes. It sits proudly among our Herkimer diamond engagement rings and our nature-inspired engagement rings.
The engagement ring
Holds the natural coffin-cut Herkimer crystal in an Art Deco filigree setting — the statement piece and focal point of the set.
The matching band
A complementary bridal band that completes the two-piece set and nests alongside the engagement ring. Also lovely from our Herkimer diamond couples rings.
The natural Herkimer “diamond”
“Herkimer diamond” is a trade name, not a claim: this is a genuine, naturally formed quartz crystal, celebrated for its exceptional glassy clarity and double-terminated shape grown in the earth. Rating about 7.5 on the Mohs scale, it is a hard, wearable stone, and its captivating black-and-white inclusions give it that avant-garde, cosmic salt-and-pepper character. Because those patterns form naturally, every stone is one of a kind — yours will share the same starry personality as our photos, with its own private constellation, reflecting the individuality of love itself. Learn the crystal’s history and value in our complete guide to Herkimer diamonds.
Bright simulated diamond accents
The Art Deco setting is studded with bright simulated diamond accents that trace the geometric filigree and add a crisp flash of white sparkle against the crystal. They are a brilliant, budget-friendly way to layer in the polished brilliance the 1920s were famous for, and they make the clarity of the coffin-cut Herkimer read even brighter. Prefer lab-grown diamond or moissanite accents instead? Message us; most of our designs can be upgraded.
Solid sterling silver with a rhodium finish
Both rings are handcrafted in solid 925 sterling silver and finished with rhodium — the same precious metal used on fine white-gold jewelry. That rhodium finish gives the set a bright, mirror-white luster and adds a protective shield that helps resist tarnish and everyday scratches, keeping the intricate filigree sharp and the silver looking freshly polished.
What the Herkimer crystal symbolizes
Long treasured as a stone of attunement and clarity, the Herkimer crystal is associated with fresh beginnings, deep connection and spiritual insight — a fitting emblem for a union as unique and enduring as the stars. Its raw, celestial beauty resonates with couples who want a ring that is unmistakably their own. If you are weighing this look against a mined stone, our comparison of the Herkimer diamond versus the salt-and-pepper diamond is a helpful read.

Sizing & care
Choose your size at checkout. If you are between sizes or unsure, we are happy to help — and if the fit is not quite right, resizing is available and starts from a modest fee. To keep the crystal and rhodium finish luminous, remove the rings before showering, swimming or applying lotions, and store them in the velvet box when not worn. A soft, dry cloth restores the shine, especially around the filigree. Curious how the stone wears over time? See our guide on whether Herkimer diamond rings are durable.
Frequently asked questions
Does this come as a set?
Yes — it is a two-piece set that includes the Art Deco Herkimer engagement ring plus a matching bridal band designed to nest alongside it. A separate matching ring for him is available on request.
Is a Herkimer diamond a real diamond?
No. “Herkimer diamond” is a trade name for a genuine natural quartz crystal that grows with diamond-like faceted points at both ends. It is a real, naturally formed gemstone — just not a member of the diamond family.
Is the center stone natural?
Yes. Each coffin-cut Herkimer is a genuine natural quartz crystal with its own salt-and-pepper inclusions, never dyed or fabricated. That is why every stone is one of a kind.
What is a coffin cut?
It is an elongated, six-sided shape with a tapered end — a bold, vintage-inspired silhouette that suits the Art Deco setting and shows off the crystal’s length and clarity.
What are the accent stones?
They are bright simulated diamonds (cubic zirconia) set into the geometric filigree. They add a crisp white sparkle and a budget-friendly touch of 1920s brilliance around the center.
How durable is it for everyday wear?
Herkimer quartz sits at about 7.5 on the Mohs scale, harder than many popular gemstones and well suited to daily wear with normal care. Avoid hard knocks and remove the rings for rough activities.
What metal is the set made from?
Solid 925 sterling silver, finished with rhodium for a bright white luster and extra protection against tarnish and scratches.
What does the rhodium finish do?
Rhodium is the same precious metal used to finish fine white gold. It gives the silver a mirror-bright, white-gold-like shine and adds a protective layer that helps the filigree and stones stay looking freshly polished.
Will my stone look exactly like the photos?
It will share the same starry, salt-and-pepper character, but the exact inclusion pattern is one of a kind. No two Herkimer crystals are identical, so your set is truly unique.
Can the rings be engraved?
Yes. You can add a personal engraving of up to 16 characters at checkout — a date, initials or a short message. Engraved pieces are final sale, so please double-check spelling.
What size should I order?
Select your ring size at checkout. If you are unsure or between sizes, contact us for guidance. Resizing is available and starts from a modest fee.
Are the stones ethically sourced?
Yes. All of our stones are ethically sourced and conflict-free, so you can wear your set with complete peace of mind.
Does it arrive gift-ready?
Every order ships in a free luxury velvet gift box and is backed by our lifetime warranty — ready for a proposal or to give as a keepsake.
