- Our custom coatings are like good quality paint: while we do our best to keep the colors consistent, there will be natural variations from batch to batch. However, the results will always be beautiful.
- If this is a concern, your salesperson can work with you to identify the most consistent custom coatings in your color palette, such as Chili Pepper, Brandy, Lemon, and Purple Haze.
- We do our best to keep our Custom Coatings consistent within a batch but based on where the stones are positioned in the coating machine, slight variation is possible. Your salesperson can advise you on what to expect.
- Due to their unusual faceting, rivolis may exhibit the coatings in uniquely beautiful ways within a single batch.
- The cut and size of the stone changes how it refracts the light, making the coatings look slightly different. All our coatings are selected to be lovely on a variety of shapes and cuts, but different stones may exhibit the coatings in uniquely beautiful ways.
- Coatings may look significantly lighter on thicker stones, beads, and pendants.
- Due to their distinctive faceting, coatings on rivolis come out in remarkable ways and will not match other stones.
- Our online color charts show a range of shapes and sizes to help illustrate the variation. Our Sales team is an excellent resource on what to expect with the stones you are interested in coating.
