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.

Customer Reviews

Overall rating: 5.0 / 5 from 615 reviews.

I love the style and how different it looks from my other jewelry.

This was a gift to myself and I am very happy with it. The color is beautiful and it feels special.

Chose the blue sapphire. It's this rich wine hue that shifts in different lighting. Obsessed.

Unique blue with halo is pure forest magic. So unique. My birthstone too.

Went with the blue sapphire. That deep ocean color with the halo is breathtaking.

The deep blue just feels so rich and luxurious. My husband keeps joking that he's off the hook for upgrading my real ring because this one looks so expensive. Joke's on him though because now I want the red one too. Best impulse purchase I've made in a long time.

I was a tiny bit worried about the sterling silver holding up since I'm rough on my hands, but it's still perfect — no scratches on the band and the prongs are snug. Delivery was way quicker than expected, maybe five days tops, and the packaging didn't scream "I bought this online" which I appreciated. My mom keeps hinting she wants one for Mother's Day, so I'll probably be back for another order real soon.

The sterling silver band has a nice solid feel to it, not flimsy at all, and I've been wearing it for about a month straight with zero tarnishing or green-finger situations.

The sparkle is noticeable indoors and outdoors. Truly stunning piece.

The sterling silver feels solid and polished. High-quality craftsmanship.

The ring arrived exactly as shown online. Even more stunning in person!

It feels comfortable enough to wear all day long. The sparkle on this ring set is incredible and it catches the light every time I move my hand. Shipping was faster than expected and the ring arrived safely packaged. It honestly looks like jewelry from a much more expensive boutique.

Beautiful ring that lives up to its sparkle.

The ring is beautiful and almost as pictured. I was a little disappointed that the centre stone was lighter than pictured in daylight. Yes, of an evening the main stone looks darker but the reality is, in normal daylight the centre stone is a lighter colour. Still it does shine lovely, fits well and overall I’m happy enough. For me, it would be perfect if it was the dark blue during the day.

Beautiful just as described . Love it!

It’s versatile enough to wear anywhere.

The compliments make me feel so good about it.

The shine has stayed perfect with no maintenance.

It’s a ring I’ll happily wear every day.

I’m so impressed with this purchase! The customer service was fantastic—they made sure all my questions were answered before I ordered.

The ring arrived promptly and was carefully packaged. It’s such a beautiful design, and the silver shines so brightly. It’s absolutely perfect!

Wow wow wow!!! The ring is phenomenal.

The ring is very pretty it’s is dainty. I ordered two they look great together and one is also perfect. I size up a half size and it still fits perfect .

Wow! This has to be the best ring in my ring collection by far. So gorgeous! I will be buying loads more. The pictures are beautiful, but nothing compared to how it looks like in real life.
