Arms granted 17th September 1937. Crest and supporters granted ?.

The Tudor rose has been an emblem of the County for many years, having appeared on an unofficial device which preceded the the grant of arms. The stags' heads are from the Cavendish arms of the Duke of Devonshire.
The dragon crest, with metal collar and pick, symbolises the county's foundation by Danes, men of dragon ships, and the county's mining and engineering enterprise. Dragons traditionally amass underground and guard great mineral wealth.
The stag and ram have special significance for Derbyshire. Deer are closely associated with the county, founded by Danish invaders of the ninth century, who named their first fort, Derby, for the wild deer that were so abundant in the area. Sheep were introduced in the New Stone Age. They were the foundation of local farming, and later provided raw materials of early cloth and leather industry on which the county's towns were based. The ram is also the county's regimental mascot.

Granted 18th October 1989.

The Borough of Amber Valley was formed by the amalgamation of the Alfreton Urban District, the Belper Urban District, the Heanor Urban District, the Ripley Urban District and the Belper Rural District.

The gold wave on the green background represents the River Amber in its valley within a white border, like the arms of the Ripley UDC, charged with five of the six horseshoes from the arms of the de Ferrers family, founders of Darley Abbey which bore the Ferrers arms and owned much of the present borough area. The two black diamonds and flaming cresset or fire-basket, like those in the arms of Alfreton UDC, indicate the coal and iron mining industries so important in the development of the area.
The tower battlements, like that in the crest of Belper RDC, refers to Codnor and other local castles and strongholds. The oak tree recalls Duffield Forest, with gold acorns an allusion also to the Oakes family prominent in Alfreton's industrial history. The tree is topped by an ancient crown of fleurs-de-lys similar to that of Henry III who often hunted in the 'Frith' Forest and had numerous possessions therein. The two gold abbatial crosiers are for Darley and Beauchief Abbeys. The mantling also refers to Heanor's textile Industry.
The unicorn is derived from the unicorn's head in the crest of Ripley. This in turn is from the crest of the Wright family, used by the Butterley Company of which John Wright was a co-founder in 1790. It wears the red collar from the neck of the popinjays or parrots of the Curzons of Kedleston; hanging from this is a red 'cross flory' from the arms of the Outrams of Butterley, co-founders of the Butterley engineering firm. The leopard is one of the supporters of the arms of the Strutts. Jedediah Strutt was the founder of the textile industry of Belper, from which Edward, his grandson, took his title as the tirst Baron Belper. The leopard also wears the Curzon collar, from which depends a gold fleur-de-lys from the arms of John of Gaunt, used by the former Belper UDC. He had a residence and hunting-lodge at Belper. The fleur-de-lys is also an emblem of St.Mary, patron saint of Crich. The whole stands on a grassy base divided by blue and white waves representing the River Derwent and other rivers in the district.
The motto is one used by the former Heanor UDC.

SUPPORTERS: On the dexter side a Cock and on the sinister side a Pynot or Magpie proper each ducally crowned Or.

Motto 'ASPIRE'.
Granted 10th November 1955.

The arms are derived from the design of the Borough's Common Seal, which bears a pomegranate tree decoratively treated. This emblem was in use by Chesterfield in the reign of Elizabeth I, and may have been derived from the pomegranate of Granada which Henry VIII had adopted as a badge on his marriage with Katherine of Aragon. It has however been claimed that the pomegranate was in use by Chesterfield long before Tudor times. For some unknown reason in the 17th century the pomegranate was discarded in favour of arms - Gules on a gold fess a lozenge azure - but the pomegranate was restored to the Seal in 1893.
The mural crown is a common symbol of civic government and the ram links the arms with the County.
The supporters each with a ducal crown commemorate the Revolution plot of 1688 at the Cock and Pynot Inn (now the Revolution House) at Old Whittington and the association of the Earl of Devonshire and other with that plot. The supporters are depicted on a base representing the rocks and moorland around the Town. The motto is both encouraging and refers to the famous "crooked spire" of the Parish Church.

Granted 12th May 1939.

The stag at rest amid palings, known locally as 'the buck in the park', has been a badge of the City from time immemorial, and may have been derived from the white hart badge of Richard II. The ram and stag are traditionally associated with the County and the broom plant is a badge of the Plantagenet kings from whom Derby received its early charters.

The Borough of Erewash was formed by the amalgamation of the Borough of Ilkeston, the Long Eaton Urban District and part of the South East Derbyshire Rural District.

The three wavy blue bands symbolise the three rivers - Trent, Derwent and Erewash. The chevron was common to the arms of Long Eaton UDC and South East Derbyshire RDC and the fleur-de-lys, emblem of St. Mary, recalls St.Mary's Abbey. The signs of Mars, prominent in the arms of the Borough of Ilkeston, represent the iron and steel industry at Stanton Ironworks and the heavy engineering aspects of the Borough. The hanks of yarn symbolise the past and present textile manufacturing trades and the wheatsheaf represents the different parishes in the Borough. The dovetailed edge of the chief symbolises the woodworking and furniture making industries.
The mural crown is a frequent symbol of civic government and the black annulets or rings, from the South East Derbyshire arms, symbolise steel-making and engineering. The torches, like that in the crest of Long Eaton, represents industry and the stag commmon to the arms of both Nottingham and Derby indicates the general geographical location of Erewash. The stag's lace collar, again common to the arms of Ilkeston and Long Eaton, represents the lace-making industry.

The Borough of High Peak was formed by the amalgamation of the Borough of Buxton, the Borough of Glossop, the New Mills Urban District, the Whaley Bridge Urban District, the Chapel-en-le-Frith Rural District and the Tintwistle Rural District.

The black points, similar to those in the arms of the Chapel-en-le-Frith RDC, represent the high peaks in the north of the district and the green base symbolises the green lowlands. The heraldic fountain refers to the lakes, reservoirs and natural mineral springs.
The chevron continues the peak motif of the arms, but here it is a single peak at the highest point of the achievement of arms, being a specific reference to the name of the Borough. The piece of Blue John is shown as if in a cave and recalls the mineral, which is a special feature of the district and known worldwide.
The stag or buck is found in the heraldry of the entire district. The stags represent the Cavendish stag, the stag of Downs, Lords of the Manor of Whaley Bridge, the buck seen in the crest of the Borough of Buxton and the stags that once roamed over the whole area.

ARMS: Or a Miner's Pick Sable surmounted of a Tudor Rose barbed and seeded proper on a Bordeure engrailed also Sable eight Annulets Gold.

Granted 20th September 1954, to the Chesterfield Rural District Council.

The North East Derbyshire District was formed by the amalgamation of the Clay Cross Urban District, the Dronfield Urban District and a majority of the Chesterfield Rural District.

The Tudor rose is derived from the arms of the County Council and the miner's pick and black border represent the mining industry. The gold rings and engrailed edging of the border are from the arms of the former Earls of Scarsdale and recall the ancient Hundred of Scarsdale.
The gold and green of the wreath represent a rural area and its agriculture. The mural crown is a common civic emblem and the crooked spire of Chesterfield Parish Church, refers the Town that gave its name to the Rural District.

Motto 'INGENIUM INDUSTRIA ALITUR'-Skill is fostered by diligence.
Granted 8th April 1954, to the Ripley Urban District Council.

The green background of the shield refers to the Royal Forest of Duffield which gives the ancient background of the district. The stags' heads, another reference to the Forest, are also from the arms of the Cavendish Dukes of Devonshire who came into possession of Ripley after the Dissolution. The chevron is for Heage or "Highedge" and also for the hilly character of the situation of Ripley. The black thinner chevron represents the coal seam lying beneath, and the Tudor rose, from the County arms, also refers to Coronation year, in which the grant of arms was sought. The fleur de lys is from a seal attributed to Darley Abbey, and is also the emblem of St. Mary patron of Crich, part of which is in the District. As the whole area was formerly in the protection of Darley Abbey, the arms are surrounded by a white border with six black horseshoes from the arms of its founders, the Ferrers family.
The black mural crown denotes a mining town, and the unicorn's head, adapted from the Wright crest which is used by the Butterley Company, rises from the flames suggesting the local heavy industries.
The motto can also be translated as "Character thrives on hard work" or "Ability thrives on industry" and is a quotation from Cicero.

Granted ?.

The South Derbyshire District was formed by the amalgamation of the Swadlincote Urban District, the Repton Rural District and part of the South East Derbyshire Rural District.

The basic pattern of the shield is that of the South East Derbyshire RDC, a green background with two gold sheaves and a gold chevron with three black rings. These represent agriculture and the iron pipe industry, three rings rather than the original four are shown here for aesthetic reasons and to emphasise the combination of three areas. The gold chevron is masoned with black to suggest the yellow brick industry denoted by the single brick in the Swadlincote UDC crest. The third wheatsheaf represents the former Repton RDC, and this gives the three wheatsheaves of Ranulph de Blunderville, Earl of Chester, whose widow Matilda moved his Priory at Calke to Repton in the late 12th century. The ermine and red chief, like the border of the Swadlincote arms, is from the arms of the Gresley family.
The black mound with flames issuing denotes coalmining and the fireclay industry. The tower, suggested by that of the Stanhope Earls of Harrington in the South East Derbyshire crest. Here it is white and shaped so as to suggest the cooling towers of Drakelow Power Station, with white clouds issuing symbolising steam.
The ermine lion is derived from the Gresley' s crest. He wears adistinctive collar showing one row of the ermine and red pieces from the Gresley arms. The wolf is derived from the supporter of the Stanhope Earls of Harrington, he is of gold with black ermine tails, and wears a collar quartered like the Stanhope's shield in ermine and red. Each beast is charged on the shoulder with a Tudor rose from the County arms.
The motto refers to the coal, fireclay and yellow brick industries and agriculture, all symbolised in the arms.
