Birthstone Rings: How to Choose the Right Gemstone by Month for a Custom Setting

Buying high-street birthstone jewellery often leads to disappointment when fragile gems crack or silver settings tarnish within six months of purchase. Designing made-to-order birthstone rings in solid 9ct, 14ct, or 18ct gold ensures your custom piece endures daily wear while keeping gemstone origins transparent and ethically sourced.

What Are the Traditional and Modern Birthstones for Each Month?

The twelve monthly birthstones range from garnet in January to tanzanite in December, offering distinct Mohs hardness ratings from 5.5 to 10 and price points starting from £220 in solid 9ct gold settings.

January: Garnet

Deep red pyrope and almandine garnets register 6.5 to 7.5 on the Mohs hardness scale. Garnets resist daily abrasion well in bezel or six-prong gold settings, with 1ct stone prices typically ranging between £220 and £450 including setting.

February: Amethyst

Amethyst is a purple variety of quartz rated 7.0 on the Mohs scale. Its rich violet tones contrast against 18ct yellow gold, with custom rings priced between £220 and £480 depending on carat size and band weight.

March: Aquamarine

Aquamarine belongs to the beryl family and measures 7.5 to 8.0 on the Mohs scale. Pale blue to deep sea-green aquamarines cost between £280 and £650 for stones between 0.75ct and 1.5ct.

April: Diamond (Natural or Lab-Grown)

Diamond ranks as the hardest natural mineral at 10 on the Mohs scale. Lab-grown diamonds match natural diamonds optical and chemical structure at a 60% to 70% lower price point, placing 1ct solitaire designs between £450 and £1,400.

May: Emerald

Emeralds rate 7.5 to 8.0 on the Mohs scale but naturally contain inclusions called jardin. Protective bezel or halo settings guard emeralds against direct impact, with prices ranging from £350 for smaller stones to £1,200+ for higher clarity options.

June: Alexandrite, Moonstone, or Pearl

Lab-grown or natural alexandrite shifts colour from teal green in daylight to ruby red under incandescent light, rating 8.5 on the Mohs scale. Custom alexandrite rings cost between £250 and £850, offering greater scratch resistance than traditional moonstones or pearls.

July: Ruby

Corundum rubies measure 9.0 on the Mohs scale, making them suited for high-wear pieces. Deep crimson natural or lab-grown rubies in solid 14ct or 18ct gold range from £350 to £1,500.

August: Peridot or Spinel

Peridot registers 6.5 to 7.0 on the Mohs scale, displaying an olive-green shade, while red or cobalt spinel measures 8.0 on the Mohs scale. Spinel offers superior scratch resistance for daily rings, priced between £220 and £550.

September: Sapphire

Sapphire ranks 9.0 on the Mohs scale and naturally occurs in blue, pink, yellow, and green hues. Sapphire options range from £320 for light blue lab-grown stones to £1,800+ for rich natural royal blue cuts.

October: Opal or Tourmaline

Tourmaline rates 7.0 to 7.5 on the Mohs scale, making it a reliable daily choice over softer opals (Mohs 5.5 to 6.5). Green or watermelon tourmalines range from £250 to £750 in custom settings.

November: Citrine or Topaz

Golden citrine (Mohs 7.0) and Imperial topaz (Mohs 8.0) provide warm yellow and orange tones. Complete 9ct gold ring designs start at £220 to £480.

December: Tanzanite, Blue Topaz, or Turquoise

Blue topaz rates 8.0 on the Mohs scale, presenting a durable alternative to delicate tanzanite (Mohs 6.5). London blue topaz solitaires range from £240 to £500.

How Do You Select a Durable Gemstone for Daily Wear?

Selecting a durable gemstone requires choosing a mineral with a Mohs hardness rating of 7.0 or higher to resist surface scratches from daily routine activities. Gemstones rated below 7.0, such as opals, pearls, and tanzanites, scratch when exposed to household dust containing airborne quartz particles.

For lower-rated stones, a protective full-bezel setting encloses the outer girdle in solid gold. Higher-rated gems like diamonds, sapphires, and rubies tolerate exposed prong settings, allowing maximum light entry through the side facets.

Which Metal Carat Weight Works Best for Custom Birthstone Rings?

Solid 9ct, 14ct, and 18ct gold alloys provide varying balances of durability, richness of hue, and market cost for custom ring settings. Every piece is stamped with its gold fineness mark (375 for 9ct, 585 for 14ct, or 750 for 18ct) in our workshop.

• 9ct Gold (375): Contains 37.5% pure gold alloyed with copper and silver, providing high scratch resistance for active wear.
• 14ct Gold (585): Contains 58.5% pure gold, delivering a rich yellow hue with physical durability for daily use.
• 18ct Gold (750): Contains 75.0% pure gold, giving an intense warm tone that complements deep gemstones like rubies and emeralds.

All Qutahia gold rings are produced in accordance with REACH nickel-release standards to ensure comfortable, skin-friendly daily wear.

How Are Multi-Stone and Toi et Moi Birthstone Rings Designed?

Multi-stone birthstone rings combine two or more distinct gemstones into a single band using balanced prong or bezel settings to represent partners, children, or family milestones. You can read a birthstone gift commission example to see how multiple family stones assemble into an asymmetrical layout.

A popular option is the Toi et Moi setting, which places two gemstones side by side to represent two individuals. You can explore stone combinations in our Toi et Moi ring UK buying guide. When pairing stones with different Mohs hardness levels, choose rubies, sapphires, or lab diamonds alongside softer stones so the harder mineral does not scratch the softer one during wear.

How Much Does a Made-to-Order Birthstone Ring Cost in the UK?

A bespoke birthstone ring in solid gold ranges from £220 for simple single-stone 9ct designs to over £2,000 for complex 18ct gold settings featuring high-grade natural rubies, sapphires, or certified lab diamonds. Pricing depends directly on metal weight, stone origin (lab-grown versus mined), and setting complexity.

Lead time for crafting is 10-14 days for simpler designs (solitaires or classic pavé bands) and 4-6 weeks for more complex commissions involving custom bezel work or multiple stones, with separate postage transit time added on top.
