The Alexander Castle 925 sterling silver heart locket necklace is our top pick because its listing states two photo windows, a 22mm x 20mm locket weighing 3.5g, and an 18” 925 sterling silver chain with a spring ring clasp. For a heart locket with an adjustable chain, the MICSAVI lists a 2.7*2.1cm locket, a suggested photo size of 1.9*1.8cm and a 45+5cm 925 silver chain; for an engravable gold plated locket, the jewellerybox round locket lists 33x21x9 mm on a 16-inch diamond cut curb chain.
This guide compares six locket necklaces from Alexander Castle, MICSAVI, jewellerybox, Yumilok and PHOCKSIN, using what each listing states: material, locket size, chain length, weight and photo windows. Stated weights run from 3.5g on the Alexander Castle to 16.4g on the jewellerybox large floating locket.
Buying guide
What should you look for in Locket Necklaces?
1Material: the Alexander Castle, MICSAVI and Yumilok listings state 925 sterling silver (MICSAVI adds cubic zirconia, with rhodium plating on the silver version). Both jewellerybox lockets are gold plated sterling silver, the round one made from recycled 925 sterling silver. The PHOCKSIN locket and chain are stainless steel.
2Photos: the Alexander Castle, MICSAVI and PHOCKSIN listings state two photo windows, and MICSAVI suggests a 1.9*1.8cm photo size. The Yumilok listing describes a photo box without a number of windows. The jewellerybox round locket is described as engravable and the jewellerybox floating locket as a floating charm locket; neither listing mentions photo windows in the features we read.
3Chain: 18” 925 sterling silver with a spring ring clasp (Alexander Castle), 45+5cm adjustable 925 silver with a spring ring clasp (MICSAVI), 45+5cm (Yumilok), 20inch-22inch adjustable stainless steel cable (PHOCKSIN), and diamond cut curb chains of 16 inches and 24 inches (jewellerybox round and floating).

5Weight: 3.5g (Alexander Castle), 5.8g (jewellerybox round), 7.7g (MICSAVI), 8.71g (Yumilok), 10g (PHOCKSIN) and 16.4g (jewellerybox floating), as each listing states.
Our process
How do we choose our picks?
We don’t lab-test products ourselves. Instead we synthesise current Amazon UK listings and published specs into clear, honest recommendations. We earn a commission if you buy through our links, but that never changes which products we rank.
Current UK availability
We check each pick against live Amazon UK catalogue data rather than last year’s model lists. Stock moves fast, so a listing can sell out after we publish.
Published specs
We compare manufacturer specifications so each pick is right for a real budget and use-case.
UK-specific fit
We factor in UK voltage and plug/fitting standards — details that generic global lists miss.

Editor's Note
None of the six listings states a warranty term. The MICSAVI listing is the one here that suggests a photo size (1.9*1.8cm); PHOCKSIN instead says its designer will edit your photo if you contact them. The two jewellerybox listings describe an engravable locket and a floating charm locket and do not mention photo windows in the features we read.
Our Take
As a default, the Alexander Castle heart locket: 925 sterling silver, two photo windows, 22mm x 20mm and 3.5g on an 18” sterling silver chain, per its listing. For an adjustable chain and a stated photo size, the MICSAVI lists a 45+5cm 925 silver chain and 1.9*1.8cm photos. For an engravable gold plated locket, the jewellerybox round locket lists 33x21x9 mm on a 16-inch diamond cut curb chain.
