Understanding the GEMS Model: A Compassionate Guide to Dementia’s Changing Abilities

The GEMS model, developed by dementia care expert Teepa Snow, offers a warm and practical way to understand the changes your loved one is experiencing. Instead of rigid stages, it uses gemstones to describe different states of ability and awareness, reminding us that dementia is fluid—someone can move between states or show traits of several at once. This approach helps you see the person behind the diagnosis and gives you concrete strategies to connect and care with less frustration. You are not alone, and there are real, doable steps you can take today.

Key points

  • The GEMS model uses gemstones (Sapphire, Emerald, Amethyst, Topaz) to describe dementia states, focusing on abilities rather than deficits.
  • Dementia is fluid—people can move between states or show traits of several at once. This is normal, not a failure.
  • Use the model to adjust your communication, routine, and safety measures to match your loved one’s current state.
  • Do not compare your loved one to others or try to force them to a higher state. Meet them where they are.
  • Your own grief is real and valid. The GEMS model can help you understand the changes, but you also need support for yourself.
  • Share the GEMS model with healthcare providers and facility staff to ensure consistent, compassionate care.

What Is the GEMS Model and Why It Matters

The GEMS model is a brain-based framework that describes dementia-related changes using the qualities of gemstones: Sapphire (early stage, clear and sharp), Emerald (mid-stage, still has many strengths but needs more support), Amethyst (later stage, more confusion, but can still experience joy), and Topaz (advanced stage, very limited awareness, but still responds to gentle touch and tone). Unlike the seven-stage Global Deterioration Scale (GDS), which can feel clinical and scary, the GEMS model focuses on what the person CAN do and how you can adapt your approach to meet them where they are. Research shows that dementia is not a neat, orderly progression—people can move back and forth between states, and symptoms from different stages can appear at the same time. This fluidity is normal, and the GEMS model gives you a flexible, hopeful lens to navigate it.

How the GEMS Model Describes Dementia-Related Changes

Each GEMS state reflects changes in the brain that affect memory, thinking, emotions, and daily function. For example, in the Sapphire state, the person might have mild memory lapses but can still manage most tasks with occasional reminders. In the Emerald state, they may struggle with planning, lose track of conversations, or need help with complex activities like finances or driving. The Amethyst state often brings increased confusion, wandering, changes in sleep, and difficulty with personal care—like forgetting to bathe or having trouble finding the toilet. The Topaz state is the most advanced, where the person may no longer walk, talk, or feed themselves, but they can still feel comfort from your presence and gentle touch. Understanding these changes helps you anticipate needs and reduce your own stress because you know what to expect and how to respond.

Why the GEMS Model Is Different from Other Stage Models

Many stage models, like the three-stage (mild, moderate, severe) or seven-stage GDS, can make you feel like you are losing your loved one in a linear, predictable way. The GEMS model, however, emphasizes that each person is unique and that their abilities can fluctuate day to day or even hour to hour. For instance, your loved one might be in an Emerald state in the morning—able to dress themselves with a little help—but slip into an Amethyst state by evening when they are tired or overstimulated. This is not a failure; it is the nature of dementia. The GEMS model gives you permission to adjust your expectations and your care in real time, which can lower your frustration and improve your connection. It also highlights that grief in dementia is not a single event but a repeating cycle of loss and adaptation—something many caregivers experience but rarely talk about.

Step-by-step

  1. Observe without judgment to notice which GEMS state your loved one is in today — focus on what they CAN still do, like recognizing a face, following a simple direction, or enjoying a familiar song.

  2. Adjust your communication to match their GEMS state — for Sapphire or Emerald, use short, clear sentences and one instruction at a time; for Amethyst or Topaz, slow down, soften your tone, and lean on gentle touch and facial expression.

  3. Build a daily routine that draws on their current strengths — Emerald may enjoy folding laundry or setting the table; Amethyst benefits from short, soothing activities like listening to music or looking through a photo album.

  4. Watch for signs of fatigue or overstimulation, which can cause a shift to a lower GEMS state — when they grow agitated, pause, reduce noise and clutter, and offer a comforting object like a soft blanket or a familiar scent.

  5. Plan for safety based on their GEMS state — for Amethyst and wandering, try door alarms or a GPS tracker; for Topaz and limited mobility, keep the bed low and floors clear of tripping hazards.

What not to do

  • Don't assume they are in the same GEMS state every day, and don't try to push them to 'move up' to a higher one — meet them where they are today.

  • Don't use the GEMS model to label or limit them, and don't compare their journey to someone else's with dementia.

  • Don't quiz, correct, or argue with them — avoid questions like 'Do you remember?' — gently redirect instead.

Practical tools

  • GEMS State Observation Checklist

    A simple daily checklist — can they follow a two-step direction? Do they recognize family? Are they able to use the toilet independently? — written on a whiteboard or in a notebook to track patterns and adjust care.

  • Calm-Down Kit for Amethyst State

    A small basket with a soft stuffed animal, a familiar music playlist, lavender-scented hand lotion, and a photo of a happy memory; offer one item at a time with a slow, gentle voice.

  • Daily Routine Template with Pictures

    A simple schedule using picture cues (toothbrush for morning care, plate for meals, bed for bedtime) posted on the wall, adjusted as their GEMS state changes.

  • Exact Phrases to Say (and Avoid)

    Emerald: 'Let's do this together. First, put on your socks.' Amethyst: 'I see you're upset. Let's sit down and rest for a minute.' Topaz: 'I'm here with you. You are safe.' Avoid questions like 'Do you remember?'

  • Wandering Prevention Tools

    Door alarms, childproof locks, a GPS smartwatch, and a black mat placed in front of the exit — many people with dementia will not step onto a dark surface.

  • Grief Journal for Caregivers

    A small notebook for your feelings, plus one positive moment each day (a smile, a shared laugh) to balance the hard parts.

Why was the GEMS model created and how does it help me focus on abilities?

The GEMS model was created by Teepa Snow to shift your focus from what your loved one has lost to what they can still do, using gemstone names that highlight their remaining abilities and awareness. This helps you see their strengths in each moment, making it easier to find small joys—like a smile from a shared song or a calm moment during a familiar task—instead of getting stuck on deficits.

How can the GEMS model help me focus on abilities and find joy in care?

The GEMS model helps you focus on abilities by naming what your loved one can still do, like recognizing faces or following simple steps, so you can plan activities that tap into those strengths. This shift builds joy into your day—celebrate a moment of connection during a task they can still manage, like folding towels together.

How can I use the GEMS state model to understand the urgency and nature of distress-driven requests like 'I want to go home'?

When your loved one says 'I want to go home' in distress, use the GEMS model to recognize they may be in a Topaz or Amethyst state where fear and confusion drive the need for safety, not a literal place. Instead of arguing, respond with warmth and a concrete action like, 'Let’s sit and have a cup of tea together, I’m right here,' which meets their emotional need for security.

How can I use GEMS to plan care around what the person can still do?

Plan care by matching activities to the GEMS state your loved one is in today—if they are in a Sapphire state, invite them to help set the table; if in Amethyst, simplify it to sorting silverware or folding napkins while you do the rest. This builds their success and reduces frustration for both of you.

How do I use gem states to understand a person's current abilities and needs, and how should I use self-awareness afterward?

Use gem states by observing what your loved one can do right now—like following a one-step instruction in an Emerald state or needing hand-over-hand guidance in Topaz—then ask yourself what you need to feel grounded, like taking three deep breaths before responding. This self-awareness keeps you calm and prevents burnout.

What is the GEMS state model and how does it apply to everyone?

The GEMS state model is a compassionate framework using gemstones (Sapphire, Emerald, Amethyst, Topaz) to describe different levels of ability and awareness, and it applies to everyone—including you—because dementia is fluid and no one stays in one state all the time. Use it to adjust your approach moment by moment without judgment.

How can I use the GEMS model to assess and plan care based on remaining abilities?

Assess remaining abilities by observing what your loved one can do in their current GEMS state—like managing simple routines in Emerald or needing full support in Amethyst—then plan care around those strengths, such as offering a short walk if they can follow directions. This practical matching reduces struggle and lets you provide just the right help.

Discuss with your clinician

Ask your doctor: ‘Based on the GEMS model, which state do you think my loved one is in, and how can we adjust their care plan?’

If your loved one is in an Amethyst or Topaz state, ask: ‘Are there any medications that might help with agitation or sleep, and what are the risks?’

For wandering or safety concerns, ask: ‘What kind of monitoring or home safety equipment do you recommend, and are there any programs that can help with costs?’

If you notice sudden changes in your loved one’s GEMS state (e.g., rapid decline), ask: ‘Could this be caused by an infection, medication side effect, or another medical issue that needs treatment?’

For your own well-being, ask: ‘Do you have any resources for caregiver stress, grief, or mental health support?’
