ALL that glitters is not gold, but there's plenty of precious metal along with stones, crystal and glass at an auction in the Cotswolds next month.

The Sparkle and Fizz sale at Moore Allen & Innocent will give bidders the chance to buy classic and modern jewellery and ornaments alongside classic champagnes and wines.

Among the standout lots in the jewellery section of this pre-Easter sale is a platinum necklace set with an opal the size of a Mini Egg.

Surrounding the stone and on the platinum suspension are beautiful diamonds.

The necklace carries an estimate of £3,500 to £4,500.

A Les Must de Cartier 18ct gold ladies wristwatch is modern by auctioneers' standards – originally sold in 1994 the watch face is surrounded by diamonds.

It commands an estimate of £2,000 to £3,000.

A single cut pear-shaped diamond of more than 0.8 carats adorns a Victorian mourning brooch, which carries an estimate of £1,500 to £2,000.

Surrounding the large diamond is a cluster of smaller diamonds forming an urn, while the hexagonal brooch is bounded by diamonds set into gold.

And an early 20th century spray brooch with diamonds set into platinum carries an estimate of £1,500 to £2,000.

From old to modern, a collection of more than 100 pieces of Swarovski Crystal ornaments will be sold over several lots, with estimates ranging from £50 to £500.

The highlight is a leaping dolphin which comes in its own fight case.

And a small collection of royal commemorative glassware features a large goblet celebrating the silver jubilee of King George V and Queen Mary. Made for Thomas Goode & Co in 1935, the 11-inch tall goblet with commemorative coins inside the stem is numbered two of a limited run of four, and carries an estimate of £200 to £300.

Accompanying the goblet is a Thomas Goode & Co commemorative mug marking the coronation of King George VI and Queen Elizabeth in 1937 (estimate £100 to £150) and a 1911 wine glass in the 18th century style, with commemorative coins inside the stem, marking the coronation of George V (estimate £100 to £150).

And from wine glasses to the wine section, a single bottle of 1919 Château Mouton Rothschild – celebrating its centenary this year – should go down well at £300 to £500.

A single bottle of Warre's Vintage Port from 1934 – considered to be one of the best vintages of the 20th century – carries an estimate of £200 to £300, while a single bottle of 1959 vintage Château Palmer is expected to achieve £100 to £150, and a single bottle of 1973 Dom Pérignon must be worth a pop at £100 to £150.

The auction takes place in Cirencester on Friday, April 5.
