This Specific Piece
The crescent moon copper design with an oxidized finish creates a visual contrast between the warm black of the metal and the mineral color of each stone. The sapphire brings the deep blue of corundum; the almandine garnet the red intensity of silicate; the labradorite the blue-green labradorescence of feldspar; the chrysoprase the soft green of nickel chalcedony; the ruby the vivid red of chromium corundum; the amethyst the purple of manganese quartz.
Each crystal is unique in shape and color distribution — the image of each variant is representative of the selected mineral.
How to Choose Your Variant
Select your preferred stone and the available size for that stone. ES sizes correspond to the inner diameter in millimeters — consult our size chart to find your measurement. There is only one unit available per size and stone type.
Minerals in the Luna Collection
The collection brings together six minerals from different gemological families: corundum (sapphire and ruby, 9 Mohs), almandine garnet (iron and aluminum silicate, 7–7.5 Mohs), labradorite (plagioclase feldspar, 6–6.5 Mohs), chrysoprase (nickel chalcedony, 6.5–7 Mohs), and amethyst (manganese quartz, 7 Mohs). Each species has its own geology, color, and history in lapidary tradition.
The symbolic properties attributed to minerals belong to cultural and historical traditions. They are shared for educational purposes, not as medical advice.
Frequently Asked Questions
Is there more than one unit per variant?
Each size and stone type generally has only one unit. Once sold out, it is not replaced with an identical crystal — each piece is unique in pattern.
How do I choose the size?
Each variant has its size indicated. ES sizes are equivalent to the inner diameter in mm. See size chart.
Can oxidized copper stain the skin?
Copper can leave a slight green mark on the skin — a natural reaction of the metal. It can be removed with soap and water. The black oxidized finish may wear off slightly with prolonged use.
Are the minerals genuine?
Yes. All crystals are natural minerals with no detectable treatment based on visual observation. The piece does not include formal gemological certification.
How do I care for it?
Avoid exposure to water and chemicals. See jewelry care guide.
