A jeweller’s guide to meaning, history and jewellery
What Are the Birthstones for March?
March has two official birthstones: Aquamarine and Bloodstone.
Both have rich histories, distinctive appearances, and very different personalities — one calm and oceanic, the other bold and symbolic.
Whether you’re choosing a gift for a March birthday, celebrating a 19th wedding anniversary, or simply drawn to the meaning behind gemstones, these two stones offer beautiful and meaningful options.
Aquamarine – The Serene Blue Birthstone for March
Aquamarine is best known for its soft, watery blue colour, instantly evoking the sea. Its name comes from the Latin aqua (water) and mare (sea), a fitting description for a gemstone long associated with oceans, sailors and calm passage.
History and symbolism of aquamarine
Throughout history, aquamarine has had a strong connection with the sea. Ancient legends claimed the stone was brought up from the depths of the ocean in the jewel caskets of sirens. Greek sailors wore aquamarine amulets carved with Poseidon, god of the sea, believing it would protect them on long voyages.
Because of this association, aquamarine became known as the sailor’s gemstone, symbolising safe travel, protection and smooth waters. Over time, its meaning expanded to include tranquillity, emotional balance and clear communication — a natural evolution from its watery origins.
Aquamarine jewellery has also long been linked with love, loyalty and harmony, making it a traditional gift for weddings and anniversaries, particularly the 19th wedding anniversary.
Aquamarine colour, formation and rarity
Aquamarine ranges in colour from pale, icy blue to deeper blue and blue-green tones. The deeper shades are rarer and therefore more valuable. The colour comes from traces of iron within the crystal.
It belongs to the beryl family (alongside emerald), and grows as six-sided crystals that can form long, elegant shapes. This is why aquamarine is often seen as larger stones in jewellery.
Aquamarine is primarily mined in Brazil, with additional sources in Madagascar, Nigeria, Zambia, Mozambique and Pakistan.
Aquamarine in jewellery
Aquamarine is particularly striking when set in white gold or platinum, which enhances its cool blue tones, though it also looks beautiful in yellow and rose gold.
At Carathea, aquamarine is most often seen in:
-
Rings
-
Pendants and necklaces
-
Elegant anniversary and birthday gifts
Its clarity, durability and timeless colour make it a gemstone that is both wearable and enduring.
Bloodstone – The Powerful Alternative March Birthstone
Bloodstone, also known as heliotrope, offers a dramatic contrast to aquamarine. It is a deep green stone flecked with distinctive red spots and veins, caused by iron oxide.
Each bloodstone is unique, and evenly coloured stones are particularly prized.
Bloodstone history and folklore
Bloodstone has a long and fascinating history. In Christian folklore, it was believed to have been formed when drops of Christ’s blood fell onto green jasper at the foot of the cross, earning it the name “The Martyr’s Stone.”
One of the most famous bloodstone carvings dates back to 1525: “The Descent from the Cross” by Matteo del Nassaro, where the natural red markings were deliberately used to depict drops of blood.
Historically, bloodstone was popular for:
-
Religious carvings
-
Seals and signets
-
Cameos and amulets
-
Men’s rings
Across cultures, bloodstone was traditionally associated with courage, strength and perseverance. Ancient Egyptians believed it enhanced physical power and protection, while medieval Europeans regarded it as an “enabler” stone — thought to help bring intentions to fruition.
(Today, these associations are appreciated as historical and symbolic rather than literal properties.)
Bloodstone formation and sources
Bloodstone is a variety of chalcedony, a form of quartz made up of microscopic crystals. It typically forms in masses rather than clear crystals and is often found in riverbeds or embedded within rock.
Major sources include India, Brazil and Australia.
Bloodstone in jewellery
Bloodstone jewellery is far rarer than aquamarine. It is most commonly seen in:
-
Signet rings
-
Beaded necklaces
-
Statement or talisman-style pieces
Its bold appearance and historical symbolism appeal to those who prefer jewellery with a strong story and character.
Choosing March Birthstone Jewellery
Aquamarine remains the most popular choice for March birthdays due to its light colour, versatility and availability. Bloodstone, by contrast, appeals to those looking for something unusual, symbolic or traditionally masculine.
Many modern March birthstone jewellery pieces also incorporate alternative stones, particularly blue topaz, which offers a similar colour to aquamarine at a lower price point.
At Carathea, our March birthstone jewellery focuses primarily on aquamarine, selected for its beauty, wearability and timeless appeal.
