1. Select A Style
Discover an array of engagement ring styles designed to reflect who you are and what you love. At Penfine, every ring begins with a story — from Nature-Inspired silhouettes to timeless Solitaires, romantic Clusters, symbolic Celtic Knots, dreamy Moon motifs, and bold Gothic designs. Each piece is thoughtfully crafted to capture emotion, meaning, and your unique connection.
If you’re planning a surprise proposal, choosing the right style becomes even more meaningful. Pay attention to your partner’s everyday fashion, accessories, and lifestyle — these subtle details often reveal whether she prefers something classic, modern, minimal, ornate, or nature-inspired. You can also check her Pinterest boards or saved posts; many people quietly bookmark their dream rings without realizing it.
Along with personalizing any of our existing designs, Penfine also welcomes fully custom creations. Whether it’s a small detail or a completely one-of-a-kind concept, we’re here to bring your vision to life.
2. Select Stones (Type)
At Penfine, Moissanite remains one of our most loved gemstones — cherished for its brilliant fire and mesmerizing iridescence. If you’re looking for color, sapphire is a beautiful choice, available in nearly every shade imaginable: classic blues, ocean teals, soft yellows, romantic purples and pinks, and even elegant white. For nature lovers, the deep green glow of emerald offers a rich, organic charm.
If you’re exploring something more distinctive, we also work with a variety of unique stones such as moss agate, alexandrite-style variegated stones, opal, sunstone, and moonstone — perfect for those who want a ring that truly stands apart.
For designs that aren’t solitaires, remember to consider the accent stones as well. The right combination of center and side stones can completely elevate the overall look.
These are just some of our most popular options, but we work with many more gemstone types. If you have a specific stone in mind that isn’t listed here, simply reach out — we’d love to help bring your vision to life.
2. Select Stones (Shapes)
Most importantly, there’s no single “right” gemstone shape — each cut has its own charm and character. Take your time exploring the different silhouettes and notice which one speaks to you. Choose the shape that feels most meaningful, and let it become the heart of your ring.

4. Select Settings & Ring Size
Stones falling out of the rings is something we never want to happen, and choosing the right settings for different center stone shapes can greatly reduce the occurrence of such incidents. The round prong setting is our most popular choice because it provides stability without obscuring too much of the stone. As for the petite claw prong, it is a combination of round prongs and claw prongs and can be considered an upgrade. It protects the center stone of the cabochon (especially opals) better than round prongs while not covering as much as claw prongs. If you would like to choose princess cut, shield cut, marquise cut, etc. as the center stone, the cornered prong maintains the sharp look while protecting the corners of the stone.
In addition to the shape of the prongs, increasing the number of prongs and changing the position can make a difference. We have listed a few common options in the picture for your reference.

7. Plan Your Perfect Proposal
Your custom engagement ring is ready — now it's time to create a moment she'll never forget! Here are some tips to make your proposal extra special:
- Choose a meaningful location: Where you first met, had your first date, or a place she's always wanted to visit.
- Incorporate personal touches: Write a handwritten letter, play her favorite song, or include loved ones (if she'd appreciate it).
- Capture the moment: Hire a photographer to secretly document the proposal, or ask a friend to take photos.
- Relax & be authentic: Speak from the heart — no need for a perfect script. Just tell her why you love her and want to spend forever together.
After she says "yes," don't forget to celebrate! Whether it's a quiet dinner for two or a gathering with friends and family, cherish the moment.
