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.
