The History of Gem Cuts & Settings in Britain
From royal treasuries to velvet-lined trinket boxes, gemstones have long whispered stories of power, love, and identity. In Britain, their use has evolved over the centuries, shaped by status, fashion, and craftsmanship.

Tudor & Elizabethan Eras (1500s–1600s)
Who owned gems?
Royalty and the very highest nobility. Gemstones were considered status symbols and political tools.
Popular gemstones:
Diamonds (uncut or point-cut), rubies, emeralds, sapphires, pearls, garnets.
Cuts & styles:
Most gems were cabochon-cut (smooth, rounded), as advanced faceting didn’t yet exist. Some were table-cut (flat on top), point-cut (pyramid-like), or rose-cut (flat underneath, domed with triangular facets on top).
Settings:
Heavy gold, closed-back settings, sometimes with coloured foils behind the stones to enhance their colour. Jewels were sewn onto clothing or worn in elaborate hairpieces.
Famous gems:
Queen Elizabeth I was gifted the Black Prince’s Ruby, now part of the Imperial State Crown.

Georgian Era (1714–1830)
Popular gemstones:
Diamonds, topaz, garnet, amethyst, citrine, paste (glass imitation).
Cuts:
Rose cut, old mine cut, table cut — designed for flickering candlelight.
Settings:
Silver settings over gold were common (silver reflects light better). Closed-back settings with foil behind stones still popular. Cluster styles emerged.
Styles:
Portrait miniatures and sentimental jewellery with hairwork; “lover’s eye” lockets. Jewels were symbolic, often spelling out names using acrostic gems (e.g. “REGARD” = Ruby, Emerald, Garnet, Amethyst, Ruby, Diamond).

Victorian Era (1837–1901)
Early Victorian / Romantic period:
Floral and serpent motifs; turquoise, amethyst, and garnet were in fashion. Snake rings (symbolising eternal love) were popularised by Prince Albert’s engagement ring to Queen Victoria.
Mid to late Victorian:
Mourning jewellery became prominent after Albert’s death. Use of jet, onyx, black enamel, and hairwork.
Cuts:
Early use of old mine and rose cuts, evolving toward more symmetrical old European cuts.
Settings:
More refined goldwork; collet settings (metal rim surrounds the stone), prong settings emerge. Brooches, lockets, and rings abundant.

Edwardian Era (1901–1910)
Popular gemstones:
Diamonds, pearls, aquamarines, amethysts.
Cuts & settings:
Delicate milgrain detailing (tiny bead-like edges), filigree metalwork, platinum settings allowed for lighter, lace-like designs.
Style:
Feminine, airy, with a focus on elegance and light. Garland style jewellery — bows, swags, and floral motifs.

Art Deco (1920s–1930s)
Cuts:
Emerald cut, Asscher cut, marquise, and calibre-cut stones (small stones cut to fit exactly together).
Gemstones:
Onyx, carnelian, jade, sapphires, diamonds. Bold colour contrasts (e.g. black and white).
Settings:
Geometric, modern designs using platinum and white gold. Cocktail rings, long necklaces, and stylish brooches flourished.

Mid-Century (1940s–1970s)
Cuts:
Introduction of brilliant-cut diamond (1950s), and increased precision in faceting. Cluster rings and solitaires became popular.
Settings:
Four-prong solitaire mounts; engraved and pierced shoulders; illusion settings (metal designed to make stones appear larger).
Gem trends:
Aquamarine, citrine, and turquoise were favoured in the 1960s–70s.

Present Day
Modern jewellers revive vintage settings like bezel, halo, and gypsy mounts. Rose-cut diamonds, coloured stones, and ethical sourcing are returning to favour. Many pieces nod lovingly to the past — just like those in The House of Gemma.
