Before asking for an OEM quote, decide which parts of the design are fixed and which are open to discussion. A clear brief gives the designer, sample maker, and buyer the same point of reference. Below is a practical way to move from an idea to an approved sample. Five COINA silver and moissanite ring designs illustrate the choices a brand might make along the way. They are design examples, not specifications for a new order. ## Start with the decisions you already have Send your sketch, reference images, or a description of the ring. If you have a physical sample, include photographs from the top, side, and underside. Useful details are: - Center stone shape and the approximate size you have in mind. - Halo, side stones, or a simpler setting. - Band width, profile, and visible surface details. - Preferred metal and finish, if decided. - Ring sizes, logo placement, packaging needs, estimated quantity, and destination market. It is fine to leave some choices open. Label them clearly so they can be resolved before a sample is made. If a reference image belongs to another brand, use it to explain a feature you like rather than asking for an exact copy. ## Use the CAD drawing to check the structure For a new design, a CAD drawing can show proportions and construction before sampling. Look at the top view, but also check the side of the setting, the band profile, stone positions, and any space around the center stone. A ring that looks balanced from above can feel different when its height or band thickness changes. Mark changes directly on the drawing and keep one approved version. The number of revisions, drawing scope, and any design charge should be agreed in the project quotation. ## Wear and inspect the sample The sample turns the drawing into something you can handle. Check the silhouette in daylight, the feel of the band, the finish at the edges, the security and appearance of the setting, and the position of any brand mark. Compare the sample with the approved drawing and written specifications. For a ring intended for daily wear, try the sample on rather than judging it only from a product image. Note any changes in writing, then approve the final sample that will guide production. Sampling charges, timing, and any later adjustment to those charges depend on the agreed project terms. ## Five ring design directions The following COINA product visuals show five silver and moissanite ring designs. They help compare shapes and settings; they do not confirm stone dimensions, a particular silver grade, plating thickness, or the available size range for a future order. Confirm those details in the specification for your own project. ### Round halo with a stone-set band A round center stone is surrounded by a halo. Smaller stones continue along the band, so the detail extends beyond the center setting. This is useful if you want a fuller face-up look. ![Round halo ring with a stone-set band on a white background](/media/blog/1ecaecad-0167-4498-b707-3822758451ef.webp) ### Square halo on a smooth band A square center and matching halo give this ring a more geometric outline. The smooth band keeps attention on the setting. ![Square halo ring on a smooth band on a white background](/media/blog/c5f21629-1083-4ec5-a894-78ed6093f7e9.webp) ### Pear halo with a stone-set band A pear-shaped center stone and matching halo create a clear direction at the top of the ring. Stones along the band add detail on either side. ![Pear halo ring with a stone-set band on a white background](/media/blog/bbd9d834-a3d0-4d9c-b744-81c06dc31624.webp) ### Pear solitaire on a smooth band The pear-shaped stone stands on its own without a halo. If you prefer a quieter design, the center stone and the band proportions become especially important to review in the sample. ![Pear solitaire ring on a smooth band on a white background](/media/blog/28c80b1e-14f5-44b5-8b30-e64961a84b11.webp) ### Round three-stone ring A round center stone is flanked by two smaller stones. Compare the side-stone scale and the height of the three settings in the CAD drawing and sample. ![Round three-stone ring on a smooth band on a white background](/media/blog/4b67d5a6-a113-45a4-b19f-f77136e731a1.webp) ## What to settle before requesting production Choose the design direction first, then ask for a written specification and quotation covering the metal, stones, finish, ring sizes, branding, packaging, quantity, sample approval, production schedule, payment, and shipping. The feasible options and terms can change with the design and order, so they should be confirmed together rather than assumed from a sample image. If you are still deciding between a halo, solitaire, and three-stone design, send those options with your brief. COINA can review the direction with you before the final specifications are set.
