Ring Size Guide
How to Measure the Inside Diameter
If you have a ring that already fits you well:
- Place the ring flat on a ruler.
- Measure the distance straight across the inside of the ring (from one inner edge to the opposite inner edge).
- This measurement (in millimeters) is the inside diameter of your ring.
- Match this number with the chart to find your ring size.

Timeless elegance meets modern romance in our 18k Solid Gold Sapphire and Diamond Engagement Ring Set. This breathtaking duo is thoughtfully crafted for those who desire a classic yet unique symbol of love. At the heart of the engagement ring sits a richly hued natural sapphire — a gemstone long cherished for its symbolism of truth, loyalty, and everlasting devotion. Its deep blue color stands out with regal sophistication, made even more captivating by a halo or flanking side stones of sparkling natural diamonds.
Paired perfectly with a matching diamond-studded wedding band, this set radiates harmony and brilliance from every angle. The wedding band is gently contoured to sit flush against the engagement ring, creating a seamless and graceful silhouette when worn together. Both rings are handcrafted in 18k solid Gold — available in yellow, white, or rose — and polished to a mirror finish to highlight the beauty of the stones and the metal’s natural shine.
Ideal for proposals, weddings, or vow renewals, this ring set is more than a piece of jewelry — it’s a lifelong promise captured in gold and stone. Whether you’re drawn to the meaningful symbolism of sapphire or the enduring brilliance of diamonds, this set offers both in perfect balance. Each piece is ethically sourced, certified, and made to order with precision and care. Elegantly packaged and ready for a moment to remember, this ring set is a modern heirloom — designed to be cherished, celebrated, and passed on.
