Buying Moissanite Jewellery from the US: UK Ring Sizes, Delivery and Materials

Buying jewellery from an overseas specialist gives you access to designs that may be difficult to find locally, but the product details need to be clear before you order. This guide explains how AdornMazing's US ring sizes compare with UK sizes, what our jewellery is made from, how our gold-plated finishes should be cared for, and what UK customers should know about delivery and returns.

Why consider moissanite?

Moissanite is a lab-created silicon-carbide gemstone valued for its brightness, fire and durability. It is not a diamond and should not be described as one. Its optical character is distinctive: many shoppers choose it because it produces vivid sparkle while allowing them to consider a larger stone or a more detailed setting at a different price point from a mined diamond.

AdornMazing uses moissanite in solitaire, halo, pavé and statement designs. Product pages specify the stone shape, carat weight and setting so you can compare pieces on their own merits rather than relying on a generic "diamond alternative" label.

Understanding S925 sterling silver and gold plating

S925 sterling silver contains 92.5% silver and is used as the structural metal in the products featured below. Some pieces have a polished silver finish; others use high-quality 18K white- or rose-gold plating over the S925 silver.

A plated piece is not solid gold, but that does not make it a low-quality material. It combines a genuine sterling-silver base with a carefully applied gold-colour finish. On the dual-tone crown ring, for example, the warm rose-gold-plated prongs contrast with the bright white-gold-plated band.

To preserve a plated finish, avoid prolonged soaking and contact with chlorine, chemically treated water, salt water, household cleaners, perfume and lotions. Brief contact with clean water should not cause a high-quality finish to fade immediately, but dry the jewellery thoroughly with a soft cloth and store pieces separately.

Converting US ring sizes to UK sizes

AdornMazing ring variants currently use US sizes. The conversions below are an approximate guide:

US size	Approximate UK size
4.5	I
5	J 1/2
5.5	K 1/2
6	L 1/2
6.5	M 1/2
7	N 1/2
7.5	O 1/2
8	P 1/2
8.5	Q 1/2
9	R 1/2
9.5	S 1/2
10.5	U 1/2
11.5	W 1/2
12.5	Y 1/2

Sizing can vary slightly by chart, band width and how a ring is intended to fit. Measure at the end of the day, when fingers are neither unusually cold nor swollen. A wide statement ring can feel tighter than a slim solitaire, so consider professional sizing before ordering an important or high-value ring. See the full international ring size guide for diameter and circumference measurements.

Five styles to compare

1. A modern two-tone engagement ring

The 1CT dual-tone crown moissanite ring uses a round moissanite, crown-style rose-gold-plated prongs, a white-gold-plated S925 silver band, pavé accents and wave detailing. It is offered in US sizes 5-9, approximately UK J 1/2-R 1/2.

2. A classic oval solitaire

The 1CT oval moissanite solitaire places a D-grade oval-cut moissanite on a slim 1.8-2.0mm S925 silver band. Its US 4.5-9 range gives UK shoppers a wider selection from approximately I-R 1/2.

3. A double-halo pendant under $150

The 0.5CT double-halo moissanite pendant features a round moissanite, twisted pavé double halo and high-quality 18K white-gold plating over S925 sterling silver. Its current US price is $108; the amount shown at checkout may be presented in another currency depending on the active Shopify Market.

4. Birthstone-colour oval hoops

The oval-cut gemstone hoop earrings are offered with lab-grown ruby, sapphire or emerald centre stones. The S925 silver has a bright white-gold finish, and current US prices range from $88 to $108 depending on the selected gemstone.

5. A wide men's statement ring

The men's 1.04CT pavé moissanite ring uses 173 round moissanites across a wide S925 silver band. It measures approximately 15.2mm at its widest point and is offered in US sizes 7.5-12.5, approximately UK O 1/2-Y 1/2. Because it is substantially wider than a solitaire, sizing deserves extra care.

UK delivery and returns

AdornMazing's current shipping policy includes the United Kingdom as an international destination and provides free standard shipping. Standard orders usually require 1-2 business days for processing; made-to-order pieces may require up to 15 business days before dispatch.

The policy does not currently publish a guaranteed UK transit-time range. Carrier and customs delays can occur, so contact AdornMazing before ordering for a fixed-date proposal, wedding, birthday or anniversary.

The current policy states that customs duties, taxes or local fees may be charged to the recipient. This treatment may be updated as AdornMazing develops its UK service, so review the information shown at checkout and the current policy before purchasing.

Unworn and undamaged standard items can generally be returned within 30 days of delivery under the return policy. Custom-made, engraved, modified, final-sale and special-order items are excluded. Contact contact@adornmazing.com for return authorisation before sending an item back.

Choosing with confidence

Start with the product facts that affect daily use: stone type, metal construction, finish, dimensions, size range and care. Then consider the visual role of the piece. A slim solitaire focuses attention on one stone, a halo adds a brighter outline, and a pavé statement ring is designed to be noticed.

For help comparing sizes or materials, contact AdornMazing before ordering. Clear answers are particularly important when a piece is intended for a proposal, milestone or time-sensitive gift.
