History of May’s Birthstone

Emerald has a long story in jewellery, treasured in ancient cultures, prized again in Georgian and Victorian Britain, and renewed in the early twentieth century with elegant platinum settings. Colombian material became especially famous, though fine stones also come from Zambia and other sources. In vintage and antique pieces you will see everything from delicate Victorian clusters to confident mid-century rings.

Symbolism and Colour

Symbolism. Renewal, love and growth are classic associations. The colour feels fresh and hopeful, which is why many people choose emerald for birthdays and milestones.

Colour. Expect a spectrum from bright spring green to deeper garden tones. Some stones lean bluish green, others golden green. Even colour with pleasing brightness is the goal; gentle internal features are common and often part of emerald’s charm.

Emerald at a Glance

What it is: emerald is the green variety of beryl.

Hardness: typically around 7.5 to 8 on the Mohs scale.

Common practice: clarity enhancement (usually oil, sometimes resin) is long-standing and should be disclosed. Care notes may differ based on the filler.

Everyday wear: rings are fine with sensible care; pendants and earrings are lower maintenance. Check settings periodically to keep stones secure. For sizing help, use the Ring Size Calculator.

Varieties and What to Expect

Colombian. Often a rich, slightly bluish green with lively brightness in fine stones.

Zambian and other sources. Can show a cooler blue-green or a slightly darker tone. Quality varies by stone; cut and clarity matter as much as origin.

Clarity. Fine internal features, often called jardin, are common. They give each stone a natural look and are considered part of emerald’s character.

Design Through the Eras

Victorian. Warm gold, seed pearls and floral motifs with delicate emerald accents.

Edwardian. Fine platinum filigree with old-cut diamond highlights and elegant ovals.

Art Deco. Geometric shapes and stepped settings. Emerald cuts and crisp bezels feel at home.

Mid century. Confident profiles with generous stones in yellow gold or mixed metals.

Natural vs Synthetic Emeralds

Most period jewellery was made with natural stones, but it is not safe to assume every emerald you see today is natural by default. Assembled Soudé doublets appeared from the late nineteenth to early twentieth century, and lab-grown emeralds entered the market in the mid-twentieth century. Antique mounts can also hold later replacement stones. Clear descriptions and, when appropriate, independent reports help you compare like for like.

• Natural emerald with filler. Emeralds often have fine fissures. Oiling is long-standing. Some stones may be resin-filled. Sellers should disclose this, as care can differ.
• Assembled Soudé doublets. Thin green layers bonded to a colourless backing or cap. Attractive and historic, but not equivalent to a single natural crystal.
• Lab-grown emeralds. Flux or hydrothermal growth since the mid-1900s. Quality varies. Proper disclosure is essential.

Practical tip. For significant purchases, ask for a gem report or buy from a specialist who discloses clearly and consistently.

Care in Brief

Use lukewarm water, mild soap and a soft brush. Pat dry with a lint free cloth. Avoid ultrasonic or steam for filled stones or when you are unsure. Keep emeralds away from harsh chemicals and extreme heat. Store pieces separately to reduce contact marks.
