This wedding ring set is inspired by elegance in motion and timeless devotion. The 4.5-carat marquise-cut engagement ring features a graceful, elongated silhouette that enhances brilliance and flatters the hand, symbolizing vitality, romance, and a love that continues to grow.

The enhancer wedding band is designed to embrace the engagement ring, adding depth, symmetry, and a refined sense of vintage-inspired charm. Together, the two rings create a harmonious and sophisticated composition, celebrating a bond that is beautifully layered, enduring, and radiant through every stage of life.

Materials

Each ring is carefully handcrafted as a refined alternative to mined diamonds. Our simulated diamonds deliver exceptional brilliance and clarity, offering dazzling sparkle while avoiding the environmental and ethical issues of traditional mining. All stones are precision-cut to high standards, ensuring balanced light reflection and captivating shine.
The band is made of premium 925 sterling silver, a durable and fully recyclable precious metal, known for its skin-friendly properties. Finished with 18K gold plating, it provides rich shine, improved resistance to tarnish, and is ideal for sensitive skin.

Size Guide(Important🔥)

Ring Size Guide

Choosing the perfect ring size is essential for comfort and style. Follow our guide below to accurately measure your finger and select your ideal size.

How to Measure Your Ring Size

Method 1: Using an Existing Ring

  1. Find a ring that fits the finger you want to size.
  2. Measure the inner diameter of the ring in millimeters (mm).
  3. Refer to our Ring Sizing Chart to find your corresponding size.

Method 2: Measuring Your Finger

If you don't have an existing ring, follow these steps to measure your finger:

  1. Wrap a thin strip of paper or a piece of string around your finger, just above the knuckle.
  2. Mark the point where the paper or string overlaps.
  3. Measure the length from the starting point to the mark in millimeters — this is your finger's circumference.
  4. Check the international ring sizing chart to find your size.
Measuring Finger Circumference

Tips for Accurate Measurement

  • Measure your finger at the end of the day when it is warm and your fingers are largest.
  • If your knuckle is wider than the base of your finger, measure both and choose a size between the two measurements.
  • For wide bands (more than 6mm), consider choosing one size larger for comfort.
  • Measure multiple times to ensure accuracy.

FREQUENTLY ASKED QUESTIONS

What are your stones made of?

All of our jewelry is crafted using premium Sona Simulated Diamonds— an exceptional alternative to natural gemstones. Sona Simulated Diamonds are engineered for superior durability and enhanced brilliance, making them more scratch-resistant and ideal for everyday wear. Designed to surpass the traditional 4Cs, they offer better optical performance than natural diamonds, delivering stunning fire and sparkle at a fraction of the price. Perfect for those who want uncompromising quality without the high cost.

Will this jewelry turn my skin green?

No, our jewelry is made from 925 sterling silver and plated with 18K gold, so it won’t turn your skin green. Green discoloration is usually caused by jewelry made from copper. We use only genuine 925 sterling silver, and the quality of our materials has been verified by the internationally recognized testing institution SGS.

Will our jewelry drop stones?

No. Each piece of jewelry is meticulously handcrafted by experienced artisans with great attention to detail. Before shipping, every item undergoes three rounds of rigorous quality inspection to ensure perfection. Our packaging is designed with shock-proof and anti-squeeze protection to keep your jewelry safe in transit. However, in rare cases, a stone may come loose if the package experiences a strong impact during delivery or if the jewelry isn't properly cared for during wear.

What if the ring size doesn’t fit?

Don’t worry — we use US standard sizing. If the ring still doesn’t fit, you can exchange or return it within 30 days as long as it hasn’t been worn.

Overall rating: 5.0 / 5 from 59 reviews.

The enhancer wraps around the marquise like they were born together. I've had friends ask if it's custom made.

Got this for our anniversary. The marquise points make my hand look so graceful.

They were BEAUTIFUL! Exactly what was advertised! I Love them so much! I get a lot of complements! 🫶

The V prongs on the marquise tips are so well done. Tiny but protective. I've snagged this ring on sweaters and nothing happened.

I was between marquise and oval. The enhancer on this marquise sealed the deal. So glad I went with this shape.

The 4.5 carat marquise with enhancer is stunning. The band wraps around like it was custom made. Fast shipping.

Took this on a beach vacation. Sand saltwater sunscreen. The enhancer stayed secure and the marquise still sparkles. Whatever plating they use is legit.

The marquise sits low and doesn't snag. The enhancer is comfortable against my other fingers.

Customer service explained how the enhancer works. I was nervous but it's actually super easy to put on.

The enhancer has these tiny stones along the band that catch light when I'm driving. Little rainbows on my car ceiling.

I wear the enhancer on its own sometimes. It's a beautiful sparkly band even without the solitaire.

The enhancer clicks into place so satisfyingly.

Gardening yoga errands. This set handles my messy life. The enhancer stays perfectly in place.

The marquise points draw the eye along my finger. The enhancer adds that extra romantic touch.

Wore the full set to my son's wedding. The marquise and enhancer combo photographed beautifully.

Marquise cut enhancer set. The most versatile and beautiful engagement ring ever created.

My sister in law thought this was a $10,000 ring. I didn't correct her.

I dropped the enhancer on a tile floor the first day. Not a scratch. Been wearing the full set for two months now and it still looks fresh out of the box.

The enhancer clicks into place and stays all day. No adjusting no fidgeting. Perfect design.

The marquise elongates my short fingers. The enhancer makes the whole set look completely custom.

I wear just the solitaire for everyday. Add the enhancer for date nights. Two completely different looks.

Gifted this to myself after a promotion. Every time I wear the full set I feel like a boss.

My husband picked this out himself. He said the enhancer reminded him of a crown. He's usually terrible at gifts but he nailed this one.

The enhancer adds that extra finger coverage I wanted without making the ring feel bulky. Perfect balance.

Worn it daily for six weeks now. Not a single issue.

The 4.5 carat is bold but the marquise shape keeps it elegant. The enhancer makes it look like a museum piece.

Took it on a weekend trip. Wore just the solitaire to the pool and the full set to dinner. So versatile.

People think it's one ring not two. The enhancer fits that seamlessly. No one believes it comes apart.

The enhancer has tiny stones that sparkle all around the marquise center. So much fire.

This set makes me feel like old Hollywood royalty.

I'm a waitress and this ring handles coffee spills and constant hand washing. The enhancer hasn't loosened once.

Sterling silver is bright on both rings. They match perfectly in color. Looks like a custom set.

This ring set makes me want to gesture more when I talk just so people notice the sparkle.

Love that I can pop the enhancer off and just wear the solitaire when I'm feeling more minimal.

I accidentally slept in this ring for three nights straight. Enhancer stayed put. No irritation on my finger at all.

This set proves you can have luxury sparkle without the luxury price tag. Absolutely stunning.

The marquise cut is so vintage Hollywood. The enhancer makes it feel modern and fresh.

The marquise catches light at both tips and the center. Enhancer amplifies every sparkle.

This set converted me to marquise cuts. The elongated shape with enhancer is pure vintage elegance.
