Description
Triangle Soft Corner Marble Coaster Set
The Triangle Soft Corner Marble Coaster Set brings a clearly shaped stone detail to tea tables, work desks and guest rooms. Its defining feature is equilateral triangle shapes with rounded corners. The design gives you a specific starting point for a custom enquiry, with the overall proportions, usable space and finish agreed before production. RS Marble Craft can discuss the proposed form in relation to the space you have available.
Choosing the size and position
Measure the base of the cups or glasses you normally use, rather than their widest upper rim. Each vessel should sit completely inside the flat usable area. On a small tea table, also check how much space remains for snacks and a serving tray. The number of coasters and any storage holder should be included in your enquiry so the quotation covers the complete set.
Suggested size: 11 × 10 × 1 cm per coaster. These are approximate planning dimensions chosen for this design, not measured dimensions of a stocked item. Any usable opening, stone thickness, base and required clearances need to be confirmed on the final specification. Custom sizing can be discussed before manufacture.
Record the overall width, depth and height in your enquiry. If the design has an opening, recess or slot, confirm its usable measurements separately from the outside size. For this design, check the space needed for equilateral triangle shapes with rounded corners. A dimensioned drawing can resolve these relationships before the stone is cut.
Comparing a circular cup base with the triangular centre
Each proposed coaster has an equilateral triangular outline with rounded corners. The full outside width and depth are not a usable circular diameter. Ask for a plan showing the continuous flat area within the edge treatment, including the rounded tips. Compare the vessel base with the central region bounded by all three sides rather than measuring only across the widest part of the triangle.
Try the actual mugs and glasses on a triangular paper template before requesting a custom size. A wide circular contact ring may require a larger outline than a narrow-based cup. Leave some positioning clearance along every side, and ask the maker to review the corner radii if the overall dimensions change. The final drawing should identify the intended seating area and measurements for each coaster.
Review the underside contact and any separate table-protection layer with the furniture finish in mind. Rounded tips are outline details and should not be used to imply tested load capacity or spill protection. Specify the required number of coasters and whether a separate holder is wanted, since neither follows from the three-sided shape. Confirm the selected white marble, surface finish and expected natural variation across the quoted set.
Marble and finish
The proposed material is white marble, subject to confirmation of the selected stone. Natural stone can show pale veins and changes in tone even within one piece. These variations should be considered when matching existing interiors. Discuss the surface finish and request suitable material information before treating the illustration as an exact colour reference.
A closer look at the design
Look at the softly rounded triangular point to see how the design is organised. The relationship between this feature and the main body matters more than adding extra ornament. A change in carving depth can make the detail quieter or more visible. If the piece will sit near other stone objects, share their sizes so the proportions can be considered together.

Practical points before ordering
Stone does not make a coaster spill proof or scratch proof. Wipe tea, coffee and coloured drinks promptly, and check that the underside suits the table finish. Ask about soft backing before ordering. A matching holder is included only when it appears in the confirmed quotation; the illustrated set quantity is indicative.
Care and handling
Dust with a soft clean cloth and remove marks gently using a product suitable for natural marble. Avoid acidic liquids, abrasive pads and strong household cleaners. Wipe spills promptly and dry the surface after light cleaning. Ask the maker about any sealer or special care required for the final finish, especially around carved recesses and joints.
Request a custom quotation
For a useful quotation, send the name Triangle Soft Corner Marble Coaster Set, your preferred measurements, the intended position and the delivery postcode. Mention the quantity and any matching pieces you need. RS Marble Craft can then confirm the proposed specification, price, production time, packing and delivery arrangements. Availability and order details are confirmed by quotation rather than inferred from this design page.
