Frequently Asked Questions
Can the 6 pieces be viewed individually in the product photos?
Yes. Each numbered variant has individual photography that allows evaluation of the band pattern. The numbering (2, 4, 5, 7, 9, 13) is from the batch and matches the piece shipped.
Does the elongated Botswana oval fit standard bezels?
Standard bezels are typically for 14×10 mm or 18×13 mm proportions — the 25–30 × 11–16 mm ovals are more elongated.
Can several different numbered pieces be purchased?
Yes, by adding each numbered variant separately to the cart. If you are looking for a specific selection by combination of sizes or patterns, please contact us before purchasing.
Is the banding visible under indoor light?
Yes. Unlike adularescence (which requires spot light), Botswana agate banding is visible under any light condition — both natural and artificial.
How to care for it?
Soft damp cloth. Hardness 6.5–7 Mohs — suitable for daily wear. Complete guide in Jewelry Care.
