I bought two tcw flat back, internally threaded studs and they are perfect. They screw in nicely, and are really pretty. They are very communicative about the process, and when to expect to receive shipment. I would definite purchase from them again.

Cushion Cut Lab Grown Diamond – Cushion cut diamond is also known as pillow cut diamond, popular for its rounded corners with a squarish shape.

Marquise Cut Lab Grown Diamond – Marquise diamond is known for its pointed corners with rounded edges.

Silver

Silver – A bright, lightweight metal with a classic shine, best suited for occasional wear.

925 Silver – Contains 92.5% pure silver blended with strengthening metals to improve durability. It offers a bright, classic silver look and is suitable for regular wear, though it may require occasional polishing to maintain its shine.
Go for a 925 silver ring if you want affordable precious metal but it might not be the best for everyday wear.

935 Silver – Made with a higher silver content than 925, resulting in a whiter, brighter finish and slightly better resistance to dulling. It feels more refined and polished while still remaining lightweight and wearable.

Gold

10K Gold – Contains more alloy metals, making it highly durable but less rich in color.

14K Gold – A perfect balance of purity, strength, and color, making it the most popular choice.
Go for 14k gold ring if you want long-lasting gold that is comfortable for everyday wear.

18K Gold – Higher gold content with a deeper, warmer color but slightly softer as less alloy is used, making it more skin-friendly and often hypoallergenic.

White Gold – Sleek and modern, often plated with rhodium for extra brightness.
Go for white gold ring if you want your diamond to stand out with maximum sparkle and contrast.

Rose Gold – Contains a higher copper content, making it stronger than yellow or white gold. The pink tone reduces visible color contrast with inclusions or lower diamond color grades.
Go for rose gold ring if you want stronger metal that visually softens diamond imperfections.

Platinum

950 Platinum – Made with 95% pure platinum, naturally white, dense, and extremely durable and fully hypoallergenic with no plating required.

Ring Size Options

Our custom solitaire rings are available in sizes 4 through 9, covering the most common finger sizes. This range ensures easy selection for everyday wear while maintaining proper balance and proportion of the ring on the finger. If you are between sizes or unsure, choosing the nearest size allows for minor future adjustments if needed, depending on the metal and design.

How to Measure Your Ring Size at Home

• Using a ring you already own: Place the ring on a ruler and measure the inner diameter (straight across the center). Match the measurement to a standard ring size chart for the most accurate result.

• Using a paper or string: Wrap a thin strip of paper or string snugly around the base of your finger. Mark where it overlaps, then measure the length in millimeters. Compare it with a ring size chart.

• Best time to measure:
Measure at room temperature. Fingers can swell in heat and shrink in cold, which may affect accuracy.

• Fit tip:
The ring should slide on easily but feel slightly snug when coming off over the knuckle.
