A full eternity ring has stones around the entire band; a half eternity ring has stones across its upper portion with a plain section underneath. The difference is stone coverage, not ring size or gemstone identity. A tennis-ring label can describe a repeated stone-set look without proving that the ring is a flexible miniature chain.
Look beyond the top view
Tiffany's eternity-ring explanation distinguishes a full circle from a top-only row of diamonds. That is a useful way to read the layout. It does not make every eternity-style ring diamond jewelry, and Tiffany's product-specific comfort or resizing statements are not promises about another maker's ring.
Compare the top, side and underside of the exact design. A front photograph can show a repeated line of stones while hiding where that line stops. If the lower section is not shown or described, ask for confirmation rather than deciding that the ring is full eternity from its brightest angle.
A historical example: one band within a ring stack
Vanity Fair's June 2019 report identified an additional eternity ring beside Meghan Markle's engagement and wedding rings. The practical lesson is to distinguish each ring's layout before choosing a stack; the article is not evidence for any Miles specification.
Editorial note: Meghan Markle is not affiliated with and does not endorse Miles Jewellery. This is independent jewelry education. Miles links are general design references, not her jewelry or a claimed replica.
What does a tennis-ring name tell you?
The Miles 3mm moissanite tennis ring is described as an eternity style with a continuous row of round moissanite. Its current material field identifies a 925 Sterling Silver base and a rhodium-plated finish; its size selector offers 5, 6, 7, 8 and 9.
Those facts identify this product's stated width, stone, base material, finish and size choices. They do not establish flexible links, a clasp or a resizing service. In particular, the word chain in a retail title is not an instruction to open, stretch or bend a ring.
Stone coverage and fit are separate checks
First decide which visible arrangement you want. Then measure for the intended finger and choose an actual available ring size. A 3mm width describes the band, not the circumference of your finger. Do not use the stone row as a substitute for a size measurement or assume a different maker's resizing advice applies.
Imagine an anniversary choice
If you are choosing an anniversary ring for someone who already wears an engagement ring, start by asking whether they want another continuous line or a separate focal shape. Compare the band from above and underneath, then check its profile beside the ring they already own. Confirm the intended finger size before choosing the available option. The useful gift decision is the arrangement and fit they want to wear, rather than assuming an eternity label guarantees compatibility with every ring stack.
Questions to settle before ordering
- Does the exact listing confirm a full or partial stone row?
- Can you see the underside and side profile?
- Are width and ring size clearly separated?
- Which stone, base material and finish belong to this product?
- If resizing matters, has the seller confirmed it for this exact design?

Does eternity mean diamond?
No. It describes a stone-row arrangement or style name. The Miles example identifies moissanite, which is neither natural nor lab-grown diamond. Check the exact stone rather than inferring it from a traditional jewelry label.
Is a half eternity ring an incomplete full ring?
No. It is a different layout with a plain section below the top stone row. Choose the arrangement deliberately; neither label alone proves better workmanship, comfort or value.
