Ring Settings

Use this checklist before you order a stock SKU or switch to Design Lab.

1. Match gemstone shape — the setting’s shape opening must match your stone (round, oval, pear, etc.).
2. Confirm millimeters — settings are sized by mm (e.g. 7x5, 8x6, 10x8). Carat alone is not enough; measure length, width, and depth.
3. Choose setting style — prong, bezel, halo, solitaire, and multi-stone each look and hold differently.
4. Check metal and finish — confirm metal, finish, and hallmark on the SKU.
5. Check which stones are included — accents may or may not ship with the mount; rely on the product description.
6. If no SKU fits, use Design Lab: https://www.syzjewelry.com/pages/designlab-custom-jewelry

A semi-mount is a ring mounting designed for a center gemstone you add separately. Some designs already include smaller accent stones; others leave the center seat blank.

Why choose a semi-mount?

• Customization: pick your own center stone—heirloom, lab-grown diamond, moissanite, sapphire, and more.
• Control: buy the mount and stone separately so you can match quality, budget, and style.
• Catalog range: Syzjewelry offers sterling silver and karat-gold mountings across shapes and styles.

Getting started

1. Measure your stone in millimeters (length × width; note depth).
2. Choose a setting that matches shape and style (solitaire, halo, vintage, men’s, etc.).
3. Have a qualified jeweler confirm fit and set the center stone.

Knowing the main setting styles helps you pick the right look and how the center stone is held.

Prong Setting

Metal claws hold the stone. Often 4 or 6 prongs. Lets in more light so the stone can look brighter. Good everyday option when a jeweler confirms the mount.

Bezel Setting

A metal rim surrounds the stone. Among the more protective styles for active wear. Often looks modern or minimalist. Bezel openings are usually less forgiving on size than open prong seats—match millimeters carefully.

Halo Setting

A ring of smaller accent stones frames the center. Can make the center look larger and adds sparkle. Confirm which accents are included on the listing.

Channel Setting

Stones sit in a metal channel, often used for wedding bands or side accents. Smooth along the finger when well made.

Pavé Setting

Many small stones set close together for a continuous sparkle. Check the product page for which pavé stones ship with the mount.

Your center stone’s shape must match the setting’s shape opening. Carat weight alone does not tell you if a stone will fit.

Match shape first

Round, oval, cushion, pear, emerald, princess, marquise, and other cuts each need a matching seat. A round stone does not fit an oval opening, even when carat weight is similar.

Then match millimeters

Use length × width in mm from the listing (for example 7×5, 8×6, 9×7). Measure your stone the same way, and note depth—deep or shallow cuts can change how the mount holds the girdle.

When nothing lines up

If no stock SKU matches shape and mm, use Design Lab or contact Syzjewelry for a custom path rather than forcing a near-size stone into the wrong seat.
