plumdiamonds.com does not allow embedding, so this is Google's rendering of the page.
Speed
Render-blocking requests
1.1 s9 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.1 s.
Main-thread work: 5.1 s
A phone's processor spends 5.1 s on main-thread work while loading, 2.5 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.
4,049 HTML elements
The page has 4,049 HTML elements. Above 1,500, rendering and every interaction get slower on phones.
8 third-party services on the page
8 third-party services load with your homepage (Shopify, gotolstoy.com and myshopify.com and others), adding 1.5 MB and 1.1 s of main-thread time.
Mobile performance score: 60
60/100Your mobile performance score is 60. Pages that score under 90 lose visitors before the first paint.
Reduce unused JavaScript
600 ms · 391 KiBAbout 391 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 600 ms faster on a phone.
Use efficient cache lifetimes
150 ms · 306 KiB21 files are served with short cache lifetimes, so returning visitors download them again (306 KiB).
Shopify adds 331 ms
331 msShopify costs a phone 331 ms of main-thread work and 724 KiB of downloads while your page loads. Loading it after the page is usable, or only on the pages that need it, takes that off the critical path.
Reduce unused CSS
300 ms · 42 KiBAbout 42 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 300 ms faster on a phone.
Improve image delivery
219 KiB15 images could be 219 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.
10 long tasks on the main thread
10 long tasks block the main thread while loading, the longest for 180 ms. During a long task the page ignores taps.
Font display
100 msWeb fonts hide text while they load. Setting font-display: swap shows text immediately (about 100 ms).
Minify JavaScript
32 KiB32 KiB could be saved by minifying JavaScript.
Duplicated JavaScript
8 KiB8 KiB JavaScript is shipped twice across bundles.
Legacy JavaScript
7 KiBPolyfills for old browsers add 7 KiB JavaScript that modern phones do not need.
Chained critical requests
Critical files load one after another instead of in parallel (3 chains). Preconnecting to key origins and preloading the hero image shortens the chain.
Forced reflow
Scripts make the browser recalculate the layout repeatedly while the page loads, which wastes processor time on phones.
Minify CSS
2 KiB2 KiB could be saved by minifying CSS.

Images and page weight
Page weight: 7.2 MB in 289 requests
7.2 MBYour homepage downloads 7.2 MB in 289 requests on a phone: fonts 4.1 MB (17), scripts 1.3 MB (79) and other files 952 KiB (110). Under 2 MB keeps phones on slow connections fast.
An image on the first screen is lazy-loaded
wedding_bands_mobile.jpg is on the first screen but marked loading="lazy", so the browser waits before fetching it and the page looks finished later. Load it eagerly (and give it fetchpriority="high" if it is the main image).
About 2.0 g of CO₂ per visit
2.03 gBy the Sustainable Web Design model, a visit to your homepage emits about 2.03 g of CO₂e: 243.9 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.
2 checks passed
Images use modern formats
Every sizeable image is WebP, AVIF or SVG.
Images are sized for phones
No image is downloaded at more than three times the size it is drawn on a phone.
Accessibility
5 text elements with low contrast
5 text elements don't have enough contrast against the background to read easily, especially outdoors on a phone.
Interactive controls must not be nested (3 elements)
Interactive controls must not be nested: 3 elements on the page fail this check, rated serious by axe-core.
44 images without alt text
44 images have no alt text, which hurts accessibility and image search.
89 links without text
89 visible links have no text or label, so screen readers cannot say where they go.
All page content should be contained by landmarks (6 elements)
All page content should be contained by landmarks: 6 elements on the page fail this check, rated moderate by axe-core.
Headings skip levels
Headings skip levels (h2 → h6, h3 → h5 and h2 → h5), which makes the page harder to scan with a screen reader.

56 automated accessibility rules passed
axe-core 4.13.0, the open-source engine behind most accessibility testing tools, ran 60 WCAG 2.2 A/AA and best-practice rules on the phone render: 56 passed and 4 failed. 4 mores need a person to judge. Automated rules catch about a third of accessibility problems; the rest need manual testing.

Content and conversion
Local business without LocalBusiness data
Your homepage shows a street address but no LocalBusiness JSON-LD, so Google and AI assistants have to guess your address, hours and phone from the page text.
No phone number on the homepage

Thin social proof
Social proof on the homepage: a star rating. Pairing it with named testimonials or customer logos makes it far more convincing.
No direct contact details
No phone number or email link on the homepage, so ready-to-buy visitors have one fewer way to reach you.
No opening hours
The homepage shows no opening hours. If customers visit or call, show when.
No map or directions link
There is no link to Google or Apple Maps. A directions link is one tap for a phone visitor.
About 1,087 words of copy
The homepage carries about 1,087 words of visible text.
