Wear sapphire with ruby, or amethyst with rock crystal and citrine, together on one finger, and wear lapis lazuli and coral separately. A harder stone scratches a softer one, so sapphire (9 on the Mohs scale) will leave marks on amethyst (7), and amethyst will scratch coral (3–4). W these elastic gemstone rings, the stones are faceted beads approx. 2–3 mm across, and the silver or 24-karat gold-plated silver is used only for the small beads between them. Six rings with these stones cost 59–99 zł, each available in sizes S, M and L.
- Rule: a harder stone scratches a softer one, so wear stones of the same hardness together on one finger.
- Pairs: sapphire with ruby (9), and amethyst with rock crystal and citrine (7). Wear lapis lazuli and coral separately.
- Construction: approx. 2–3 mm beads on elastic. The 925 silver or gold-plated silver is only in the small beads, and those will be scratched first, because silver has a Mohs hardness of approx. 2.5–3.
- Size: S 48–51 mm, M 52–55 mm, L 56–59 mm finger circumference.
Stones all the way around the finger, without a setting
W an elastic ring, the stones go all the way around the finger, including the palm side, and nothing protects them. W a classic ring, the setting sits on a metal band, with only metal on the palm side.
Put two such rings on one finger, and the beads of one will rub against the beads of the other. That’s why the hardness of the stones determines which ones to wear together.
Which stones not to wear together on one finger
Do not wear stones of different hardness on the same finger: sapphire or ruby (9 on the Mohs scale) next to amethyst, rock crystal or citrine (7), or lapis lazuli (5–6) and coral (3–4) next to any other stone. W on the Mohs scale, a stone with a higher number will scratch one with a lower number.
Equally hard stones can also scratch each other, so ruby can leave a mark on sapphire, and sapphire on ruby. W this pair, however, neither stone has an advantage over the other.
Rules for pairing stones based on their energy are a matter of belief. When beads rub against each other on the same finger, hardness matters.
| Ring | Mineral and Mohs scale, what to wear on one finger and what to avoid |
|---|---|
| Sapphire | Corundum, 9; wear with ruby; avoid softer stones next to it (they’re the ones that will get scratched) |
| Ruby | Corundum, 9. With sapphire. Avoid softer stones next to it (they’re the ones that will get scratched) |
| Amethyst | Quartz, 7; wear with rock crystal and citrine; avoid having sapphire and ruby next to it, and prolonged sunlight |
| Rock crystal and citrine |
Quartz, 7; wear with amethyst; avoid having sapphire and ruby next to it, and prolonged sunlight |
| Lapis lazuli | Rock, mainly lazurite, 5–6; wear separately; avoid washing dishes, cream, and perfume |
| Coral | Organic material, 3–4; wear separately; avoid hot water and ultrasonic cleaners |
| Beads | Silver and gold-plated silver, about 2.5–3; present in every ring; avoid rubbing against stones in neighboring rings |
Sapphire with ruby: two corundums, 9 on the Mohs scale
Sapphire and ruby have the same hardness and together are the hardest stones in our elastic rings. The Sapphire Ring for PLN 89 has dark navy, almost black in places, faceted beads about 3 mm across.
Pair it with a ruby ring. W the Ruby Ring for PLN 99, the raspberry-red beads are the same size as those in the sapphire ring, and there’s one larger ruby bead between two small metal beads. Wear the amethyst one finger away from this pair.
Amethyst with rock crystal and citrine: quartz, 7
Amethyst, rock crystal, and citrine are varieties of the same mineral, quartz, so they have the same hardness. The Amethyst Ring for PLN 79 has purple faceted beads about 3 mm across and two small metal beads.
W the Rock Crystal and Citrine Ring for PLN 89, the colorless crystal beads are about 3 mm, and the pale yellow citrine beads are about 2 mm. Amethyst and citrine can fade after prolonged exposure to strong sunlight, so don’t leave them on a windowsill.
Lapis lazuli: 5–6, wear alone and for going out
Lapis lazuli is a rock composed mainly of lazurite, calcite, and pyrite. It ranks 5–6 on the Mohs scale, so any stone from either pair can scratch it.
The cobalt-blue beads, about 3 mm, in the Lapis Lazuli Ring for PLN 79 have golden flecks, and there’s one larger bead between two small metal beads. Wear it on its own on one finger, and put your other rings on other fingers. Lapis lazuli is porous, so this is a ring for going out: take it off when washing dishes, and put it on only after applying cream and perfume.
Coral: 3–4, the most delicate, wear separately
Coral is an organic material: a calcium carbonate skeleton built by tiny marine polyps. Each of the other stones is harder than coral. W In the Coral Ring, priced at PLN 59, the faceted beads are about 2 mm, and the coral is dyed red. There is a small bead of silver or gold-plated silver between the beads.
Don’t wear it with other stones on the same finger, and take it off before doing any manual work. Don’t wash coral in hot water or in an ultrasonic cleaner.
Silver and gold-plated beads scratch first
Silver has a Mohs hardness of about 2.5–3, so it is softer than the stones in five of the rings and nearly as soft as coral. That’s why, when worn on one finger, the metal beads are the first to show marks from rubbing against the stones on neighboring rings.
Gold plating is a layer of 24-karat gold over 925 sterling silver, and gold has the same Mohs hardness as silver. The coating is thin and can wear away over time in areas of constant friction, revealing the silver underneath.
You can wear the silver and gold-plated versions together on one hand. When wearing several rings at once, how well their shapes go together matters more than the metal.
Size S, M, L, and an elastic cord that doesn’t like getting wet
Each of the six rings comes in three finger circumference sizes: S 48–51 mm, M 52–55 mm, and L 56–59 mm. W In Polish sizing, these correspond approximately to S 8–11, M 12–15, and L 16–19, because Polish ring size is roughly the finger circumference minus 40.
If your circumference falls outside these ranges, choose the closest size and enter your exact finger circumference in the order comments. W At our boutique on Grzybowska Street, we’ll measure your finger with sizing rings and help you choose the right size.
A soaked elastic cord loses its elasticity faster. Take off your rings before bathing or washing up.
If you prefer one larger stone to beads on elastic cord, see our article on the stone ring from 150 PLN: it features rings carved entirely from agate, with rock crystal, and with druzy, each in one fixed size.
Rings with other stones, also available in silver or gold-plated silver, are in the elastic ring collection.
Pink or yellow corundum is also sapphire, as that’s what we call corundum in every color except red. Red corundum is ruby, and its color comes from chromium impurities.
