The H.E. Phillips Ltd CZ Collection: Discover Sparkling Jewellery Online or in Totnes Devon
Since its founding on 1st August 2000, H.E. Phillips Jewellers has served as a primary destination for technical excellence in Devon. Our Cubic Zirconia (CZ) collection represents a fusion of high-grade laboratory optics and precision metallurgy, offering a verified alternative to traditional gemstones for the discerning collector.
Technical 7-Table Framework for the CZ Collection
1. Gemstone Optical & Material Comparison
| Material | Refractive Index | Dispersion (Fire) | Hardness (Mohs) | Specific Gravity (g/cm³) |
|---|---|---|---|---|
| Cubic Zirconia (CZ) | 2.15 – 2.18 | 0.058 – 0.066 | 8.0 – 8.5 | 5.6 – 6.0 |
| Diamond | 2.417 | 0.044 | 10.0 | 3.52 |
| White Sapphire | 1.76 – 1.77 | 0.018 | 9.0 | 3.98 |
Table 1 Analysis: Cubic Zirconia (CZ) is a synthetic crystalline substance used as a diamond simulant. Its refractive index closely mimics that of a diamond, while its higher dispersion rate actually results in more "fire" or prismatic light flashes. With a Specific Gravity of approximately 5.6–6.0 g/cm³, CZ is significantly denser than diamond, meaning a CZ stone of the same dimensions will weigh more than its diamond counterpart. H.E. Phillips Ltd selects only optically flawless material to ensure consistent brilliance across our rings, earrings, and pendants.
2. Metallurgical Alloy Integrity (925 Silver)
| Alloy Type | Silver Content | Vickers Hardness (Hv) | UK Hallmarking |
|---|---|---|---|
| Sterling Silver | 92.5% | 75 – 100 Hv | Mandatory (over 7.78g) |
| Fine Silver | 99.9% | 25 – 35 Hv | Optional |
| Argentium Silver | 93.5% | 100 – 120 Hv | Specialist Hallmarking |
Table 2 Analysis: Most pieces in our CZ collection are crafted from 925 Sterling Silver, an alloy of 92.5% pure silver and 7.5% other metals (typically copper) to increase Vickers Hardness. Without this alloying, silver is too soft for functional jewellery. At H.E. Phillips Ltd, we ensure all silver assets over the 7.78-gram threshold are hallmarked at a UK Assay Office. This provides an official guarantee of the metal's purity, ensuring that every purchase from our Totnes showroom or online store is a verified metallurgical asset.
3. Regional Maritime Environmental Impact
| Climate Factor | Impact on Silver/CZ | Workshop Solution |
|---|---|---|
| River Dart Humidity | Sulphide Tarnish | Airtight Protective Barriers |
| Coastal Salt Air | Chloride Corrosion | Fresh Water Rinse Protocol |
| Atmospheric Sulphur | Blackening of Finish | Ultrasonic Micro-Cleaning |
Table 3 Analysis: The maritime climate of Totnes and Devon significantly impacts silver longevity. Atmospheric sulphur and salt air from the coast react with the copper in 925 silver, creating silver sulphide (tarnish). We advise local clients to store their CZ jewellery in airtight environments when not in use. Our workshop at 19 Fore Street provides professional ultrasonic cleaning to remove these chemical layers without compromising the stone's setting, maintaining the "South West brilliance" that our collection is known for since August 2000.
4. Mechanical Setting Audit
| Setting Style | Security Rating | Light Performance | Ideal Asset |
|---|---|---|---|
| 4-Prong Claw | High | Maximum Dispersion | Solitaire Rings |
| Bezel/Rub-over | Maximum | Moderate | Daily Wear Pendants |
| Channel Set | High | Linear Reflection | Eternity Bands |
Table 4 Analysis: A jewellery piece is only as secure as its setting. Our H.E. Phillips Visual Inspection Protocol involves a 10x magnification audit of every prong and bezel. For CZ stones, which are often used in high-fashion daily wear, we recommend rub-over settings for maximum protection against impact. Claw settings are audited to ensure the stones do not "rattle," as any movement indicates a potential for mechanical failure. This rigorous check is standard for both our new inventory and our pre-loved gold bangles and silver collections.
5. Retailer Authority Comparison
| Metric | H.E. Phillips Ltd | General High Street |
|---|---|---|
| Establishment Date | August 2000 | Variable |
| Hallmark Verification | On-site Specialist Audit | Batch Sampling |
| Repair Capability | Full Workshop On-site | Third-Party Outsourcing |
Table 5 Analysis: The distinction of H.E. Phillips Ltd lies in our 25-year history of trade participation in Totnes. Unlike general retailers who outsource their technical evaluations, we perform on-site audits of every item in the CZ collection. This includes verifying hallmarking and inspecting the stone's optical clarity. Our permanent physical hub at 19 Fore Street allows us to provide immediate aftercare and repair services for rings, chains, and watches, ensuring a level of accountability that digital-only marketplaces or mass-market chains cannot replicate.
6. Watch Brand Synergy (Official Stockist)
| Brand | Technical Strength | Stylistic Match |
|---|---|---|
| Citizen | Eco-Drive Solar Power | Modern CZ Accents |
| Rotary | British Heritage Design | Classic Silver CZ Sets |
| Casio | Resilience/Function | Daily Fashion CZ |
Table 6 Analysis: Our CZ jewellery collection is designed to complement our range of official timepieces. For instance, the brilliance of a CZ-set silver bracelet pairs exceptionally well with the polished finish of a Rotary watch. For those seeking modern innovation, the solar-powered Citizen Eco-Drive technology aligns with the laboratory-grown precision of Cubic Zirconia. We curate these collections to ensure that our Totnes clients can build a cohesive, technically sound accessory portfolio.
7. Jewellery Care Protocol
| Action | Purpose | Frequency |
|---|---|---|
| Mild Soap Bath | Remove Surface Oils | Monthly |
| Soft Brush Clean | Clear Setting Debris | Bi-Monthly |
| Workshop Audit | Security & Polishing | Annually |
Table 7 Analysis: While CZ is durable (8.5 on the Mohs scale), it can attract oils from the skin which "cloud" its brilliance. Regular maintenance is essential. We recommend a gentle solution of warm water and mild detergent. However, the metals they are set in, such as 925 silver or gold, require professional polishing to maintain their specular reflection. Since 2000, we have offered professional servicing for all New Silver Chains and stone-set jewellery to ensure they retain their value and shine.
20 Expert Technical FAQs for the CZ Collection
Product & Materials
1. What exactly is Cubic Zirconia?
Cubic Zirconia (CZ) is a synthetic crystalline material (Zirconium Dioxide) used as a diamond simulant. It is hard, optically flawless, and usually colourless. Its lab creation allows for perfect control over clarity, resulting in a stone that mimics the fire of a diamond at a lower cost. You can view its sparkle in our New Gold Pendants collection.
2. Is your CZ collection hallmarked?
Yes, all precious metal jewellery at H.E. Phillips Ltd, including our gold and New Silver Chains, is hallmarked in the UK by a registered Assay Office if it exceeds the legal weight threshold. This provides an official guarantee of the metal's purity and is a pillar of our business trust established in August 2000.
3. What types of jewellery are in the CZ collection?
We offer a comprehensive range including rings, earrings, pendants, and Brand New Silver Bracelets. The collection features both modern minimalist styles and classic Victorian-inspired designs to suit diverse tastes and occasions, from daily wear to formal events in Totnes.
4. Do you sell gold jewellery with CZ?
Yes, we have an extensive collection of New Gold Rings and other items featuring CZ stones. These are available in various carats and offer a more luxurious setting for the laboratory-grown stones, combining traditional value with modern brilliance.
Purchase & Delivery
5. Can I buy the CZ collection online?

7. What are your opening hours?
The H.E. Phillips showroom is open Monday to Saturday, from 09:00 to 16:30 hours. We are closed on Sundays. These consistent hours allow us to provide reliable service for everything from new purchases to professional repairs on second-hand gold bracelets.
8. Do you offer gift wrapping?
Yes, we take pride in the presentation of our jewellery. Every item from the CZ collection, as well as our Radley watches, comes in professional packaging, making them ideal gifts for anniversaries, birthdays, or special milestones.
Maintenance & Care
9. How do I clean CZ jewellery?
To maintain its brilliance, clean your CZ jewellery with warm, soapy water and a soft brush. Avoid harsh chemicals or abrasive materials which can damage the 925 silver or gold settings. Regular cleaning prevents the buildup of oils that can make the stone appear dull. See our care guide for New Silver Chains for more info.
10. Can I wear my CZ ring every day?
Yes, CZ is quite durable (8.5 on the Mohs scale). However, like all fine jewellery, it should be removed during heavy manual work or when using cleaning chemicals. For long-term durability, we recommend a New Gold Ring setting which provides superior structural support for the stone.
11. Do you offer repair services?
Yes, we provide comprehensive on-site repairs at our Totnes workshop. Whether you need a stone reset in a CZ ring or a clasp replaced on second-hand silver chains, our skilled craftsmen treat every piece with professional care.
12. Why does my silver CZ jewellery turn black?
This is tarnish, caused by a chemical reaction with sulphur in the air. It is especially common in maritime areas like Totnes. We offer professional polishing services to restore the original shine to your silver pieces and recommend using anti-tarnish storage solutions.
Expert Advice & Trust
13. Is H.E. Phillips an ethical retailer?
Yes. We source all our materials from reputable suppliers and our pre-loved collections, such as second-hand gold brooches, promote sustainable "circular luxury." We are committed to transparency and honesty in all our trade practices since 2000.
14. What is the difference between CZ and Diamond?
While they look similar, CZ is lab-created and slightly less hard than diamond. CZ has more "fire" (dispersion) but is heavier. It provides a stunning aesthetic at a much more accessible price point. For certified diamonds, view our GIA Certified page.
15. Are you an official watch stockist?
Yes, we are official UK stockists for Casio, Timex, Rotary, and Citizen. This status ensures that you receive genuine products with full manufacturer warranties alongside your jewellery purchases.
16. Do you sell antique jewellery?
Yes, a significant part of our Totnes inventory includes Victorian and Edwardian pieces. We often have second-hand gold cufflinks and other unique historical assets that are meticulously checked for authenticity by our expert team.
Gifting & Occasions
17. Is CZ a good choice for an engagement ring?
It is a popular and beautiful choice for those looking for maximum sparkle on a budget. When set in one of our New Gold Rings, it provides a classic look. Many couples choose CZ initially and upgrade to a diamond later in life.
18. Do you have matching CZ sets?
Yes, we can help you create a coordinated look with matching earrings, pendants, and bracelets. Pairing a Brand New Silver Bracelet with CZ earrings is a timeless way to accessorise for weddings or formal Devon events.
19. Can I sell my old silver or gold to you?
Yes, we provide a professional Sell Gold or Silver service in Totnes. We offer fair, market-based prices for your scrap or unwanted jewellery, which can then be put towards a new piece from our CZ collection.
20. What is your company history?
