The centre is set with a square cut royal blue sapphire measuring approximately 5.63 x 5.63mm. The stone has a rich, saturated blue colour and is held within a platinum setting. The sapphire appears to be lab grown, a technology that entered commercial production during the Art Deco period and would have been a point of interest when the ring was made.\u003c\/p\u003e\n\u003cp\u003eSurrounding the sapphire are twelve small diamonds arranged within a square platinum head. The outer edge of the head is finished with fine milgrain detail. The upper shoulders are also in platinum and carry small illusion style diamond details before transitioning into the plain 18ct yellow gold band. The gallery beneath the head is pierced and open, allowing light into the central stone.\u003c\/p\u003e\n\u003cp\u003eInside the band is the early British 18CT PLAT mark, indicating the combined use of 18ct gold and platinum. The combination of an 18ct yellow gold band with a platinum head is typical of higher quality British rings from the late 1920s and 1930s. Platinum was favoured around diamonds and pale stones because its cool tone blended with the settings and allowed fine, precise work such as milgrain borders and illusion detailing.\u003c\/p\u003e\n\u003cp\u003eSapphire is the birthstone for September.\u003c\/p\u003e\n\u003cp\u003eThe ring is supplied with the period jewellery box shown in the photographs.\u003c\/p\u003e\n\u003chr\u003e\n\u003cp\u003e\u003cstrong\u003eCondition\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eVery good antique condition.
